Now, for the first time, artificial intelligence (AI) has mastered teamwork in a complex first-person video game, coordinating its actions with both human and computer teammates to consistently beat opponents.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\">\u201cThe scale of the experiments is remarkable,\u201d says Michael Littman, an AI expert at Brown University. Getting AI agents to work together is incredibly tough, he says.<\/span><\/p>\n<p style=\"text-align: justify;\"><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/-5KQw7PiVFI\" width=\"760\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><span data-mce-type=\"bookmark\" style=\"display: inline-block; width: 0px; overflow: hidden; line-height: 0;\" class=\"mce_SELRES_start\">\ufeff<\/span><\/iframe><\/p>\n<p id=\"interstitial-container\" style=\"text-align: justify;\"><span style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\">Although AI can drive cars and easily\u00a0defeat the world\u2019s greatest chess and Go players one on one, researchers have struggled to get it to master teamwork. The practice may seem intuitive to us, but predicting how others will behave\u2014a crucial component of working on a team\u2014adds a whole new level of complexity and uncertainty for AI to deal with.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\">In the new study, researchers got AI bots to teach each other to work as a team. Their classroom was a simplified version of 1999 first-person shooter,\u00a0<em>Quake III Arena<\/em>. The game involves two teams that navigate around a 3D map to retrieve a flag from their opponent\u2019s base and return it to theirs. The team with the most captures after 5 minutes wins. Players also fire a laser to tag enemies, sending them back to their home base.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\">To train the AI to work as a team, the scientists created 30 different bots and pitted them against each other in a series of matches on randomly generated maps. The bots trained using brain-inspired algorithms called neural networks, which learn from data by altering the strength of connections between artificial neurons. The only data the bots had to learn from was the first-person visual perspective of their character and game points, awarded for things like picking up flags or tagging opponents.<\/span><\/p>\n<p>&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;..<\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\">By\u00a0Edd Gent<\/span><\/p>\n<p style=\"text-align: justify;\"><strong><span style=\"font-family: helvetica, arial, sans-serif; font-size: 14pt;\"><i>Read more at:\u00a0<a href=\"https:\/\/www.sciencemag.org\/news\/2019\/05\/artificial-intelligence-learns-teamwork-deadly-game-capture-flag\" target=\"_blank\" rel=\"noopener noreferrer\">Science<\/a><\/i><\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Go and\u00a0Chess were among the child\u2019s play.
