The algorithm also learned racing techniques such as drifting, overtaking and blocking, following the track&#8217;s unwritten etiquette.<\/p>\n<p><iframe loading=\\\"lazy\\\" width=\\\"675\\\" height=\\\"380\\\" src=\\\"https:\/\/www.youtube.com\/embed\/E1O45EHjkns\\\" title=\\\"YouTube video player\\\" frameborder=\\\"0\\\" allow=\\\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\\\" allowfullscreen><\/iframe><\/p>\n<p>To create GT Sophy, engineers used deep reinforcement learning. The algorithm was placed in an environment where it, within a few hours, learned the game&#8217;s rules on its own, and after \\&#8221;a day or two\\&#8221; was able to drive faster than 95% of drivers in the training set.<\/p>\n<p>The developers also designed a reward system. For example, they fine-tuned penalties for the AI for collisions with other cars. This helped cultivate an aggressive driving style in the agent without intimidating other racers.<\/p>\n<p>Training of the algorithm took place on the DART cloud platform developed by Sony AI. The laboratory team used more than a thousand PlayStation 4 consoles.<\/p>\n<p>The AI agent went on to beat some of the world&#8217;s best Gran Turismo Sport players. In July 2021, the algorithm lost to racer Takuma Miyazono, and to three other leading players. Three months later, in a rematch, the AI defeated the humans.<\/p>\n<p>In a team race, the algorithm outscored the human players twofold.<\/p>\n<p>Hiroaki Kitano, CEO of Sony AI, said GT Sophy represents a significant milestone in artificial intelligence.<\/p>\n<blockquote class=\\\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\\\">\n<p>&#8220;In addition to contributing to the gaming community, we believe this breakthrough opens up new opportunities in areas such as autonomous racing, autonomous driving, high-speed robotics and control,&#8221; he said.<\/p>\n<\/blockquote>\n<p>The developers plan to add the algorithm to other Gran Turismo games. Players may obtain Sophy as a driving coach or a racing partner.<\/p>\n<p>GT Sophy is the result of a collaboration between Sony Interactive Entertainment (SIE), the Gran Turismo Polyphony Digital (PDI) developer, and Sony AI&#8217;s innovation laboratory.<\/p>\n<p>In April 2021, Sony patented <a href=\"https:\/\/u1f987.com\/en\/news\/sony-patents-ai-that-plays-video-games-for-users\">AI, which plays video games instead of a user<\/a>.<\/p>\n<p>In July that year, the FIFA 22 developers reported using machine learning to create realistic footballer animations.<\/p>\n<p>In the same month, an AI enthusiast used neural networks to copy a working fragment of GTA V.<\/p>\n<p>Subscribe to ForkLog News on Telegram: <a href=\\\"https:\/\/t.me\/forklogAI\\\" target=\\\"_blank\\\" rel=\\\"noreferrer noopener nofollow\\\">ForkLog AI<\/a> \u2014 all the AI news!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sony unveiled GT Sophy, an artificial intelligence capable of defeating the world&#8217;s top Gran Turismo players.<\/p>\n","protected":false},"author":1,"featured_media":57501,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"select":"1","news_style_id":"1","cryptorium_level":"","_short_excerpt_text":"","creation_source":"","_metatest_mainpost_news_update":false,"footnotes":""},"categories":[3],"tags":[438,1155,1663],"class_list":["post-57500","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-and-analysis","tag-artificial-intelligence","tag-games-and-gamefi","tag-sony"],"aioseo_notices":[],"amp_enabled":true,"views":"16","promo_type":"1","layout_type":"1","short_excerpt":"","is_update":"","_links":{"self":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts\/57500","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/comments?post=57500"}],"version-history":[{"count":1,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts\/57500\/revisions"}],"predecessor-version":[{"id":57502,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/posts\/57500\/revisions\/57502"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/media\/57501"}],"wp:attachment":[{"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/media?parent=57500"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/categories?post=57500"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/u1f987.com\/en\/wp-json\/wp\/v2\/tags?post=57500"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
