139-806: Advance Wars: Dual Strike , known as Famicom Wars DS in Japan , is a turn-based strategy video game developed by Intelligent Systems and published by Nintendo for the Nintendo DS handheld game console . It is the third installment in the Advance Wars series (the first on the DS) and was released in 2005 for Japan on June 23, in North America on August 22, in Europe on September 30 and in Australia on March 22, 2006. The game

278-581: A loss function . Variants of gradient descent are commonly used to train neural networks. Another type of local search is evolutionary computation , which aims to iteratively improve a set of candidate solutions by "mutating" and "recombining" them, selecting only the fittest to survive each generation. Distributed search processes can coordinate via swarm intelligence algorithms. Two popular swarm algorithms used in search are particle swarm optimization (inspired by bird flocking ) and ant colony optimization (inspired by ant trails ). Formal logic

417-494: A low unemployment rate of around 2.6%. Its poverty rate is the second highest among the G7 countries, and exceeds 15.7% of the population. Japan has the highest ratio of public debt to GDP among advanced economies, with a national debt estimated at 248% relative to GDP as of 2022 . The Japanese yen is the world's third-largest reserve currency after the US dollar and the euro. Japan

556-676: A security alliance . The United States is a major market for Japanese exports and a major source of Japanese imports, and is committed to defending the country, with military bases in Japan. In 2016, Japan announced the Free and Open Indo-Pacific vision, which frames its regional policies. Japan is also a member of the Quadrilateral Security Dialogue ("the Quad"), a multilateral security dialogue reformed in 2017 aiming to limit Chinese influence in

695-472: A "degree of truth" between 0 and 1. It can therefore handle propositions that are vague and partially true. Non-monotonic logics , including logic programming with negation as failure , are designed to handle default reasoning . Other specialized versions of logic have been developed to describe many complex domains. Many problems in AI (including in reasoning, planning, learning, perception, and robotics) require

834-685: A battle in the middle of the Crimson Sea. After destroying the last Black Obelisk, the Allied Nations proceed to the final battle where they fight Von Bolt and a giant oozium known as the Grand Bolt. After destroying the Grand Bolt, Hawke (or Jake, based on the player's decision) destroys Von Bolt's life support chair, supposedly causing both Hawke and Von Bolt to die in the aftermath. With the Black Obelisks gone, Omega Land begins returning to normal. Hawke

973-460: A contradiction from premises that include the negation of the problem to be solved. Inference in both Horn clause logic and first-order logic is undecidable , and therefore intractable . However, backward reasoning with Horn clauses, which underpins computation in the logic programming language Prolog , is Turing complete . Moreover, its efficiency is competitive with computation in other symbolic programming languages. Fuzzy logic assigns

1112-652: A country's commitment to environmental sustainability. Japan is the world's fifth-largest emitter of carbon dioxide . As the host and signatory of the 1997 Kyoto Protocol , Japan is under treaty obligation to reduce its carbon dioxide emissions and to take other steps to curb climate change. In 2020, the government of Japan announced a target of carbon-neutrality by 2050. Environmental issues include urban air pollution ( NOx , suspended particulate matter , and toxics ), waste management , water eutrophication , nature conservation , climate change , chemical management and international co-operation for conservation. Japan

1251-505: A factory is captured. Multiplayer for this mode is supported, unlike Survival. Up to eight players on up to four teams can battle. Computer-controlled units, which take on a gray color, may also be added into a match. A demo of Dual Strike , containing the Combat mode, can be sent wirelessly to other DS units. Dual Strike fields extensive multiplayer modes that come in two forms: Versus mode and Link mode. In Versus mode, only one DS system

1390-539: A kingdom in central Japan in 660 BC, beginning a continuous imperial line . Japan first appears in written history in the Chinese Book of Han , completed in 111 AD. Buddhism was introduced to Japan from Baekje (a Korean kingdom) in 552, but the development of Japanese Buddhism was primarily influenced by China. Despite early resistance, Buddhism was promoted by the ruling class, including figures like Prince Shōtoku , and gained widespread acceptance beginning in

1529-479: A large cooperative sector, with three of the world's ten largest cooperatives, including the largest consumer cooperative and the largest agricultural cooperative as of 2018 . It ranks highly for competitiveness and economic freedom . Japan ranked sixth in the Global Competitiveness Report in 2019. It attracted 31.9 million international tourists in 2019, and was ranked eleventh in

1668-450: A large movement and firing range; and the Oozium, a gelatinous blob which can only move one space per turn, but it can destroy any enemy it comes into contact with instantly. There are two new naval units: the "Black Boat", which can repair and resupply any allied unit next to it, while capable of transporting two infantry/mech units; and the aircraft carrier , which can house two air units and

1807-462: A loss of the "unique and enjoyable" aspects of the game. In Japan, Famitsu gave it a score of two nines and two eights for a total of 34 out of 40. Detroit Free Press gave it a score of all four stars and said: "There are campaigns that will keep you awake at night, second-guessing your tactics, long after you shut the DS off". The New York Times gave it universal acclaim: "With the new features and

1946-479: A major catalyst for further administrative reforms. These reforms culminated with the promulgation of the Taihō Code , which consolidated existing statutes and established the structure of the central and subordinate local governments. These legal reforms created the ritsuryō state, a system of Chinese-style centralized government that remained in place for half a millennium. The Nara period (710–784) marked

2085-611: A new CO power named " Tag Power" or "Dual Strike" can be used. It allows players to use both COs' Super CO powers consecutively in the same turn, and effectively allows the player to have two turns. Finally, COs in Dual Strike gain experience and can be promoted after each victorious battle in the War Room or Campaign. Higher ranked COs have access to different skills to tune and enhance their fighting styles. Abilities vary in type and benefit; some improve attack or defense, others increase

2224-543: A new constitution emphasizing liberal democratic practices. The Allied occupation ended with the Treaty of San Francisco in 1952, and Japan was granted membership in the United Nations in 1956. A period of record growth propelled Japan to become the second-largest economy in the world; this ended in the mid-1990s after the popping of an asset price bubble , beginning the " Lost Decade ". In 2011, Japan suffered one of

2363-462: A new system of taxation. The true aim of the reforms was to bring about greater centralization and to enhance the power of the imperial court, which was also based on the governmental structure of China. Envoys and students were dispatched to China to learn about Chinese writing, politics, art, and religion. The Jinshin War of 672, a bloody conflict between Prince Ōama and his nephew Prince Ōtomo , became

2502-558: A new weather effect called the Sandstorm decreases both visibility and the attack range of all indirect fire units. The 28 missions (including an integrated tutorial and several secret lab missions unlocked by capturing a certain property in another mission) in Campaign mode that make up the game's storyline are objective-based, with most requiring the player to capture an enemy property. Some missions in Dual Strike's campaign make use of

2641-710: A numerical ranking from 0–300, in addition to the letter ranking. These are converted to points and are added to the player's overall points, which can be used to purchase War Room maps, Versus maps, and COs. Bonus points can also be earned by destroying certain items, such as Oozium or Black Obelisks in certain missions. Hard Campaign can be unlocked, which is a more difficult version of the standard campaign. All unlocked COs can be used in Hard Campaign, including those unavailable in Normal Campaign. Three save slots are available for Campaign Mode. Several new modes were added to

2780-429: A path to a target goal, a process called means-ends analysis . Simple exhaustive searches are rarely sufficient for most real-world problems: the search space (the number of places to search) quickly grows to astronomical numbers . The result is a search that is too slow or never completes. " Heuristics " or "rules of thumb" can help prioritize choices that are more likely to reach a goal. Adversarial search

2919-614: A population of nearly 124 million as of 2024, and is the eleventh-most populous country . Its capital and largest city is Tokyo ; the Greater Tokyo Area is the largest metropolitan area in the world, with more than 38 million inhabitants as of 2016. Japan is divided into 47 administrative prefectures and eight traditional regions . About three-quarters of the country's terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains . The country sits on

3058-460: A significant shift to urbanization. The early 20th century saw a period of Taishō democracy (1912–1926) overshadowed by increasing expansionism and militarization . World War I allowed Japan, which joined the side of the victorious Allies , to capture German possessions in the Pacific and China in 1920 . The 1920s saw a political shift towards statism , a period of lawlessness following

3197-481: A system of terraces is used to farm in small areas. This results in one of the world's highest levels of crop yields per unit area, with an agricultural self-sufficiency rate of about 50% as of 2018 . Japan's small agricultural sector is highly subsidized and protected . There has been a growing concern about farming as farmers are aging with a difficult time finding successors. Artificial intelligence Artificial intelligence ( AI ), in its broadest sense,

3336-488: A time with the touchpad. Each has strengths and weaknesses when graded in the four categories of firepower, rate of fire, movement speed, and capture speed, and their respective strengths and weaknesses resemble those of the units in the main game. Players must fight through six levels, each on a different map against a different CO. Units are bought before the first game of each set and must last through all six levels, as extra units cannot be purchased and can only be gained when

3475-721: A tool that can be used for reasoning (using the Bayesian inference algorithm), learning (using the expectation–maximization algorithm ), planning (using decision networks ) and perception (using dynamic Bayesian networks ). Probabilistic algorithms can also be used for filtering, prediction, smoothing, and finding explanations for streams of data, thus helping perception systems analyze processes that occur over time (e.g., hidden Markov models or Kalman filters ). The simplest AI applications can be divided into two types: classifiers (e.g., "if shiny then diamond"), on one hand, and controllers (e.g., "if diamond then pick up"), on

3614-669: A wide range of techniques, including search and mathematical optimization , formal logic , artificial neural networks , and methods based on statistics , operations research , and economics . AI also draws upon psychology , linguistics , philosophy , neuroscience , and other fields. Artificial intelligence was founded as an academic discipline in 1956, and the field went through multiple cycles of optimism, followed by periods of disappointment and loss of funding, known as AI winter . Funding and interest vastly increased after 2012 when deep learning outperformed previous AI techniques. This growth accelerated further after 2017 with

3753-487: A wide variety of techniques to accomplish the goals above. AI can solve many problems by intelligently searching through many possible solutions. There are two very different kinds of search used in AI: state space search and local search . State space search searches through a tree of possible states to try to find a goal state. For example, planning algorithms search through trees of goals and subgoals, attempting to find

3892-1139: Is intelligence exhibited by machines , particularly computer systems . It is a field of research in computer science that develops and studies methods and software that enable machines to perceive their environment and use learning and intelligence to take actions that maximize their chances of achieving defined goals. Such machines may be called AIs. Some high-profile applications of AI include advanced web search engines (e.g., Google Search ); recommendation systems (used by YouTube , Amazon , and Netflix ); interacting via human speech (e.g., Google Assistant , Siri , and Alexa ); autonomous vehicles (e.g., Waymo ); generative and creative tools (e.g., ChatGPT , and AI art ); and superhuman play and analysis in strategy games (e.g., chess and Go ). However, many AI applications are not perceived as AI: "A lot of cutting edge AI has filtered into general applications, often without being called AI because once something becomes useful enough and common enough it's not labeled AI anymore ." The various subfields of AI research are centered around particular goals and

4031-523: Is reclaimed land ( umetatechi ). Lake Biwa is an ancient lake and the country's largest freshwater lake. Japan is substantially prone to earthquakes , tsunami and volcanic eruptions because of its location along the Pacific Ring of Fire. It has the 17th highest natural disaster risk as measured in the 2016 World Risk Index. Japan has 111 active volcanoes. Destructive earthquakes, often resulting in tsunami, occur several times each century;

4170-430: Is 377,975.24 km (145,937.06 sq mi). Japan has the sixth-longest coastline in the world at 29,751 km (18,486 mi). Because of its far-flung outlying islands, Japan's exclusive economic zone is the eighth-largest in the world, covering 4,470,000 km (1,730,000 sq mi). The Japanese archipelago is 67% forests and 14% agricultural . The primarily rugged and mountainous terrain

4309-691: Is a unitary state and constitutional monarchy in which the power of the Emperor is limited to a ceremonial role . Executive power is instead wielded by the Prime Minister of Japan and his Cabinet , whose sovereignty is vested in the Japanese people. Naruhito is the Emperor of Japan, having succeeded his father Akihito upon his accession to the Chrysanthemum Throne in 2019. Japan's legislative organ

4448-641: Is a body of knowledge represented in a form that can be used by a program. An ontology is the set of objects, relations, concepts, and properties used by a particular domain of knowledge. Knowledge bases need to represent things such as objects, properties, categories, and relations between objects; situations, events, states, and time; causes and effects; knowledge about knowledge (what we know about what other people know); default reasoning (things that humans assume are true until they are told differently and will remain true even when other facts are changing); and many other aspects and domains of knowledge. Among

4587-459: Is an input, at least one hidden layer of nodes and an output. Each node applies a function and once the weight crosses its specified threshold, the data is transmitted to the next layer. A network is typically called a deep neural network if it has at least 2 hidden layers. Learning algorithms for neural networks use local search to choose the weights that will get the right output for each input during training. The most common training technique

4726-462: Is an interdisciplinary umbrella that comprises systems that recognize, interpret, process, or simulate human feeling, emotion, and mood . For example, some virtual assistants are programmed to speak conversationally or even to banter humorously; it makes them appear more sensitive to the emotional dynamics of human interaction, or to otherwise facilitate human–computer interaction . However, this tends to give naïve users an unrealistic conception of

4865-444: Is an unsolved problem. Knowledge representation and knowledge engineering allow AI programs to answer questions intelligently and make deductions about real-world facts. Formal knowledge representations are used in content-based indexing and retrieval, scene interpretation, clinical decision support, knowledge discovery (mining "interesting" and actionable inferences from large databases ), and other areas. A knowledge base

5004-422: Is anything that perceives and takes actions in the world. A rational agent has goals or preferences and takes actions to make them happen. In automated planning , the agent has a specific goal. In automated decision-making , the agent has preferences—there are some situations it would prefer to be in, and some situations it is trying to avoid. The decision-making agent assigns a number to each situation (called

5143-422: Is armed with surface-to-air missiles. In addition, the cruiser 's missiles are now able to damage all naval units, making it more versatile. A new air unit, the stealth fighter , has the ability to use stealth and turn invisible to all but adjacent enemy units. Similar to the submarine, the stealth bomber uses more fuel when stealth is activated, but it can only be attacked by certain units. The other new air unit

5282-629: Is betrayed and Von Bolt attempts to swarm Hawke and Lash with Oozium 238. After the Allied Nations’ COs save Hawke and Lash, the COs, along with Hawke and Lash, begin to turn the tide against the Black Hole Army. Both Hawke and Lash provide valuable intelligence of the Black Hole weaponry and its plans for Omega Land. With this information, the Allied Nations slowly corner the Black Hole Army, leading to

5421-413: Is classified based on previous experience. There are many kinds of classifiers in use. The decision tree is the simplest and most widely used symbolic machine learning algorithm. K-nearest neighbor algorithm was the most widely used analogical AI until the mid-1990s, and Kernel methods such as the support vector machine (SVM) displaced k-nearest neighbor in the 1990s. The naive Bayes classifier

5560-507: Is divided into 47 prefectures, each overseen by an elected governor and legislature. In the following table, the prefectures are grouped by region : 7.  Fukushima 14.  Kanagawa 23.  Aichi 30.  Wakayama 35.  Yamaguchi 39.  Kōchi 47.  Okinawa A member state of the United Nations since 1956, Japan is one of the G4 countries seeking reform of

5699-687: Is governed by the Ministry of Defense , and primarily consists of the Japan Ground Self-Defense Force , the Japan Maritime Self-Defense Force , and the Japan Air Self-Defense Force . The deployment of troops to Iraq and Afghanistan marked the first overseas use of Japan's military since World War II. The Government of Japan has been making changes to its security policy which include the establishment of

5838-413: Is labelled by a solution of the problem and whose leaf nodes are labelled by premises or axioms . In the case of Horn clauses , problem-solving search can be performed by reasoning forwards from the premises or backwards from the problem. In the more general case of the clausal form of first-order logic , resolution is a single, axiom-free rule of inference, in which a problem is solved by proving

5977-636: Is located in the Pacific Ocean off the northeast coast of the Asian mainland , and is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south. The Japanese archipelago consists of four major islands— Hokkaido , Honshu , Shikoku , and Kyushu —and thousands of smaller islands , covering 377,975 square kilometres (145,937 sq mi). Japan has

6116-487: Is not heavy, but the islands usually develop deep snowbanks in the winter. In the Sea of Japan region on Honshu's west coast, northwest winter winds bring heavy snowfall during winter. In the summer, the region sometimes experiences extremely hot temperatures because of the Foehn . The Central Highland has a typical inland humid continental climate, with large temperature differences between summer and winter. The mountains of

6255-511: Is preceded by Advance Wars 2: Black Hole Rising and Advance Wars and succeeded by Advance Wars: Days of Ruin . Advance Wars is the international title of the Wars video game series, which dates back to the Family Computer game Famicom Wars in 1988. The storyline is a continuation of the previous two games and is set in the new location of Omega Land. Black Hole has returned under

6394-400: Is reportedly the "most widely used learner" at Google, due in part to its scalability. Neural networks are also used as classifiers. An artificial neural network is based on a collection of nodes also known as artificial neurons , which loosely model the neurons in a biological brain. It is trained to recognise patterns; once trained, it can recognise those patterns in fresh data. There

6533-439: Is restricted for habitation. Thus the habitable zones, mainly in the coastal areas, have very high population densities: Japan is the 40th most densely populated country even without considering that local concentration. Honshu has the highest population density at 450 persons/km (1200/sq mi) as of 2010 , while Hokkaido has the lowest density of 64.5 persons/km as of 2016 . As of 2014 , approximately 0.5% of Japan's total area

6672-513: Is revealed to have stolen Von Bolt's chair and escaped, leaving Von Bolt either dead or barely alive. With the power in Von Bolt's chair Hawke revives all the land. Dual Strike was first announced under the title Advance Wars: DS as a first-party DS release in a Nintendo press release in October 2004 and it was to be released in the year following the DS's release. In March, the Japanese release date

6811-475: Is the National Diet , a bicameral parliament . It consists of a lower House of Representatives with 465 seats, elected by popular vote every four years or when dissolved, and an upper House of Councillors with 245 seats, whose popularly-elected members serve six-year terms. There is universal suffrage for adults over 18 years of age, with a secret ballot for all elected offices. The prime minister as

6950-578: Is the Black Bomb, which can self-destruct, damaging units around it. Other new features include the Com Tower , a new property that, when captured, increases the firepower of all allied units, although it provides no funds and cannot perform repairs. Black Crystals heal Black Hole units surrounding them. The Black Obelisk, which has the approximate look of a Black Cannon, also functions like a Black Crystal. The Rain weather effect now triggers Fog of War. Lastly,

7089-576: Is the oldest unamended constitution in the world. Statutory law originates in the legislature, and the constitution requires that the emperor promulgate legislation passed by the Diet without giving him the power to oppose legislation. The main body of Japanese statutory law is called the Six Codes . Japan's court system is divided into four basic tiers: the Supreme Court and three levels of lower courts. Japan

7228-404: Is the process of proving a new statement ( conclusion ) from other statements that are given and assumed to be true (the premises ). Proofs can be structured as proof trees , in which nodes are labelled by sentences, and children nodes are connected to parent nodes by inference rules . Given a problem and a set of premises, problem-solving reduces to searching for a proof tree whose root node

7367-468: Is to defeat the enemy army with their own army. Except in some campaign missions with special objectives, there are two ways to defeat an opponent: destroy all of the enemy's units or capture their headquarters. The battle system is turn-based tactics. Two to four armies, each headed by one or two commanding officers (COs), take turns building and commanding units on grid-based maps. Every turn, units, which consist of ground, sea and air units, can move across

7506-560: Is typically used in everyday speech and reflects shifts in Japanese phonology during the Edo period . The characters 日本 mean "sun origin", which is the source of the popular Western epithet "Land of the Rising Sun". The name "Japan" is based on Min or Wu Chinese pronunciations of 日本 and was introduced to European languages through early trade. In the 13th century, Marco Polo recorded

7645-440: Is used for game-playing programs, such as chess or Go. It searches through a tree of possible moves and counter-moves, looking for a winning position. Local search uses mathematical optimization to find a solution to a problem. It begins with some form of guess and refines it incrementally. Gradient descent is a type of local search that optimizes a set of numerical parameters by incrementally adjusting them to minimize

7784-455: Is used for reasoning and knowledge representation . Formal logic comes in two main forms: propositional logic (which operates on statements that are true or false and uses logical connectives such as "and", "or", "not" and "implies") and predicate logic (which also operates on objects, predicates and relations and uses quantifiers such as " Every X is a Y " and "There are some X s that are Y s"). Deductive reasoning in logic

7923-436: Is used in AI programs that make decisions that involve other agents. Machine learning is the study of programs that can improve their performance on a given task automatically. It has been a part of AI from the beginning. There are several kinds of machine learning. Unsupervised learning analyzes a stream of data and finds patterns and makes predictions without any other guidance. Supervised learning requires labeling

8062-576: Is used, and the single DS is passed from player to player. These matches can be set up with any combination of human players and computer-controlled armies. Link mode is the same game as Versus mode gameplay-wise, but each player has a separate console and copy of Dual Strike . Two to eight people can participate in wireless multiplayer games. Maps created by players by the Map Editor can also be traded wirelessly to other players. Dual Strike stars two new characters: Jake, and Rachel, Jake's advisor. These are

8201-557: Is very heavy, especially during the rainy season. The main rainy season begins in early May in Okinawa, and the rain front gradually moves north. In late summer and early autumn, typhoons often bring heavy rain. According to the Environment Ministry, heavy rainfall and increasing temperatures have caused problems in the agricultural industry and elsewhere. The highest temperature ever measured in Japan, 41.1 °C (106.0 °F),

8340-905: Is when the knowledge gained from one problem is applied to a new problem. Deep learning is a type of machine learning that runs inputs through biologically inspired artificial neural networks for all of these types of learning. Computational learning theory can assess learners by computational complexity , by sample complexity (how much data is required), or by other notions of optimization . Natural language processing (NLP) allows programs to read, write and communicate in human languages such as English . Specific problems include speech recognition , speech synthesis , machine translation , information extraction , information retrieval and question answering . Early work, based on Noam Chomsky 's generative grammar and semantic networks , had difficulty with word-sense disambiguation unless restricted to small domains called " micro-worlds " (due to

8479-407: Is where the main battle takes place, while the top screen is used to display the terrain and unit intelligence . However, in some missions, the top screen shows a second front. The second front is a second battle that is waged simultaneously with the battle on the lower screen, which is integral to some missions. The player can change the top screen back to the intel screen and vice versa, and units in

SECTION 60

#1732854610829

8618-479: Is written using the kanji 日本 and is pronounced Nihon or Nippon . Before 日本 was adopted in the early 8th century, the country was known in China as Wa ( 倭 , changed in Japan around 757 to 和 ) and in Japan by the endonym Yamato . Nippon , the original Sino-Japanese reading of the characters, is favored for official uses, including on Japanese banknotes and postage stamps. Nihon

8757-850: The shōgun led to the Boshin War and the establishment of a centralized state nominally unified under the emperor (the Meiji Restoration ). Adopting Western political, judicial, and military institutions, the Cabinet organized the Privy Council , introduced the Meiji Constitution (November 29, 1890), and assembled the Imperial Diet . During the Meiji period (1868–1912), the Empire of Japan emerged as

8896-416: The 1923 Tokyo earthquake killed over 140,000 people. More recent major quakes are the 1995 Great Hanshin earthquake and the 2011 Tōhoku earthquake, which triggered a large tsunami. The climate of Japan is predominantly temperate but varies greatly from north to south. The northernmost region, Hokkaido, has a humid continental climate with long, cold winters and very warm to cool summers. Precipitation

9035-459: The Asuka period (592–710). In 645, the government led by Prince Naka no Ōe and Fujiwara no Kamatari devised and implemented the far-reaching Taika Reforms . The Reform began with land reform, based on Confucian ideas and philosophies from China . It nationalized all land in Japan, to be distributed equally among cultivators, and ordered the compilation of a household registry as the basis for

9174-530: The Battle of Sekigahara in 1600. He was appointed shōgun by Emperor Go-Yōzei in 1603 and established the Tokugawa shogunate at Edo (modern Tokyo). The shogunate enacted measures including buke shohatto , as a code of conduct to control the autonomous daimyō , and in 1639 the isolationist sakoku ("closed country") policy that spanned the two and a half centuries of tenuous political unity known as

9313-512: The Chūgoku and Shikoku regions shelter the Seto Inland Sea from seasonal winds, bringing mild weather year-round. The Pacific coast features a humid subtropical climate that experiences milder winters with occasional snowfall and hot, humid summers because of the southeast seasonal wind. The Ryukyu and Nanpō Islands have a subtropical climate , with warm winters and hot summers. Precipitation

9452-579: The Early Mandarin Chinese pronunciation of the characters 日本國 as Cipangu . The old Malay name for Japan, Japang or Japun , was borrowed from a southern coastal Chinese dialect and encountered by Portuguese traders in Southeast Asia , who brought the word to Europe in the early 16th century. The first version of the name in English appears in a book published in 1577, which spelled

9591-575: The Edo period (1603–1868). Modern Japan's economic growth began in this period, resulting in roads and water transportation routes, as well as financial instruments such as futures contracts , banking and insurance of the Osaka rice brokers . The study of Western sciences ( rangaku ) continued through contact with the Dutch enclave in Nagasaki . The Edo period gave rise to kokugaku ("national studies"),

9730-720: The Indo-Pacific region, along with the United States, Australia, and India. Japan is engaged in several territorial disputes with its neighbors. Japan contests Russia's control of the Southern Kuril Islands , which were occupied by the Soviet Union in 1945. South Korea's control of the Liancourt Rocks is acknowledged but not accepted as they are claimed by Japan. Japan has strained relations with China and Taiwan over

9869-719: The Kurils . The Allies (led by the United States) repatriated millions of Japanese settlers from their former colonies and military camps throughout Asia, largely eliminating the Japanese Empire and its influence over the territories it conquered. The Allies convened the International Military Tribunal for the Far East to prosecute Japanese leaders except the Emperor for Japanese war crimes . In 1947, Japan adopted

10008-634: The National Security Council , the adoption of the National Security Strategy, and the development of the National Defense Program Guidelines. In May 2014, Prime Minister Shinzo Abe said Japan wanted to shed the passiveness it has maintained since the end of World War II and take more responsibility for regional security. In December 2022, Prime Minister Fumio Kishida further confirmed this trend, instructing

The Japanese variant of capitalism has many distinct features: keiretsu enterprises are influential, and lifetime employment and seniority-based career advancement are common in the Japanese work environment . Japan has

12788-421: The agent can seek information to improve its preferences. Information value theory can be used to weigh the value of exploratory or experimental actions. The space of possible future actions and situations is typically intractably large, so the agents must take actions and evaluate situations while being uncertain of what the outcome will be. A Markov decision process has a transition model that describes

12927-510: The agent may not be certain about the situation they are in (it is "unknown" or "unobservable") and it may not know for certain what will happen after each possible action (it is not "deterministic"). It must choose an action by making a probabilistic guess and then reassess the situation to see if the action worked. In some problems, the agent's preferences may be uncertain, especially if there are other agents or humans involved. These can be learned (e.g., with inverse reinforcement learning ), or
