AlphaGo continue donc d\u2019\u00e9tonner et il vient de cr\u00e9er la surprise en remportant deux manches sur le meilleur des cinq manches que les deux joueurs doivent disputer, et tout \u00e7a face au 3e mondial du jeu de go, Lee Sedol.<\/p>\n

Une prouesse qu\u2019absolument personne ne sentait venir. Dans une interview publi\u00e9e dans Nature, les chercheurs estimaient qu\u2019AlphaGo avait des capacit\u00e9s lui permettant de se situer pr\u00e8s du 279e rang mondial<\/strong>.<\/p>\n

A priori, Lee Sedol n\u2019avait pas de quoi \u00eatre inquiet, il avait d\u2019ailleurs signal\u00e9 \u00eatre en mesure de battre cette intelligence artificielle 5 manches \u00e0 0 ou 4 manches \u00e0 1<\/strong>. Le pari est d\u2019ores et d\u00e9j\u00e0 perdu. Apr\u00e8s l'ordinateur qui se fait passer pour un adolescent, voici celui qui bat le champion du jeu de Go.<\/p>\n

Les parties ont \u00e9t\u00e9 diffus\u00e9es sur YouTube via la cha\u00eene Deepmind et la prochaine rencontre aura lieu samedi 12 \u00e0 4 h 30 du matin heure fran\u00e7aise. D\u00e9taillons les deux premi\u00e8res qui se sont d\u00e9roul\u00e9es \u00e0 Seoul.<\/p>\n

La premi\u00e8re partie a \u00e9t\u00e9 tr\u00e8s disput\u00e9e et c\u2019est seulement apr\u00e8s 3 heures d\u2019un match \u00e2pre<\/strong>, que Lee Sedol a admis sa d\u00e9faite. Il avait pourtant une longueur d\u2019avance apr\u00e8s deux heures de jeu, o\u00f9 il a employ\u00e9 des coups rarement utilis\u00e9s pour d\u00e9sar\u00e7onner son adversaire.<\/p>\n

En fin de partie, alors que les combinaisons se r\u00e9duisent, la capacit\u00e9 de penser de la machine a pris le dessus et l\u2019avance de Lee Sedol s\u2019est retrouv\u00e9e r\u00e9duite \u00e0 n\u00e9ant.<\/p>\n

La deuxi\u00e8me partie n\u2019a pas vu Lee Sedol jeter l\u2019\u00e9ponge, mais ext\u00e9nu\u00e9 par le combat pr\u00e9c\u00e9dent, et il a subi l\u2019agressivit\u00e9 du jeu d\u2019Alphago, et a perdu de deux points au bout des cinq heures de jeu<\/strong> de temps imparti.<\/p>\n

La troisi\u00e8me pourrait n\u00e9anmoins sceller le sort du champion, qui se devra de r\u00e9agir sous peine de perdre la confrontation sans avoir remport\u00e9 un match. Le fondateur d'Android avait sans doute raison lorsqu'il signalait que l'intelligence artificielle serait la prochaine r\u00e9volution.<\/p>\n","protected":false},"excerpt":{"rendered":"Alors qu’on lui promettait l’enfer, l’intelligence artificielle Alphago m\u00e8ne 2 manches \u00e0 0 face \u00e0 Lee Sedol, class\u00e9 au 3e rang mondial du jeu de Go, une v\u00e9ritable prouesse qui montre les avanc\u00e9es de la technologie, Sedol devra vite se rattraper pour ne pas finir bredouille de cette bataille en 5 manches.","protected":false},"author":4,"featured_media":253666,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5187],"tags":[51],"class_list":["post-253658","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-logiciels","tag-google"],"acf":[],"yoast_head":"\n
