Din cate am vazut pe Chinezi ii intereseaza mai mult sa faca un program care sa-l bata pe AlphaGo decat sa joace AlphaGo cu Ke Jie.

Eu intelesesem ca DeepMind nu va continua sa considere dezvoltarea AlphaGo o prioritate dupa meciul cu Lee Sedol, urmand sa se orienteze spre alte domenii. Deci nu prea inteleg de ce ar vrea sa se bata chinezii cu AlphaGo in conditiile astea :)

Aveti aici o traducere cu comentariile lui Lee Sedol despre meciurile sale cu AlphaGo. Inca nu e tradus si meciul 5 dar cred ca va fi la aceeasi pagina traducerea. http://badukinkorea.tumblr.com/

Foarte interesanta perspectiva lui Lee Sedol.

Pornind de la link-ul din postarea ta, am gasit un alt link catre pagina asta la fel de interesanta: ("Lee Sedol about the Go board in his head")

Acolo spune despre 9dan Pro ca ar fi "the highest possible rank". Cu multi ani in urma pe cand jucam Go, parca am auzit undeva si de 10 dan, intr-un articol despre cei mai mari jucatori din istorie. A fost vreodata un jucator 10 dan? Acum de ce nu se mai acorda acest titlu?

Coreenii lucreaza la un AlphaGo coreean. :) http://english.etnews.com/20160518200003

Iar aici un articol interesant; http://www.wired.com/2016/05/google-alpha-go-ai/

Dupa succesul AlphaGo foarte multi incearca sa il ajunga din urma , dar drumul e lung.

Aveti aici o partida intre HajinLee si CrazyStone (care incearca sa foloseasca si el noile tehnologii) https://www.youtube.com/watch?v=ZdrV2H5zIOM

Comentariile lui Rémi Coulom dupa un rezultat "nu prea satisfacator" :
"I was also very disappointed by the way Crazy Stone played. I had played plenty of games on KGS to calibrate levels before the release, and it did reach 7d with a 4-core machine at 1 second per move. I expected a 18-core server with 20 seconds would be considerably stronger.

From my quick analysis, it seems that the neural network makes the search too selective, so searching deeper does not help. You correctly analyzed that it did not anticipate B E8. I will tune selectivity at longer time controls, to see if I can fix it. I had done some testing and tuning before the release, but mostly in self-play. Playing humans reveals interesting weaknesses that are not visible otherwise. I don't have strong enough gtp opponents besides my previous version, unfortunately.

Anyway, I will try hard to fix these problems."

Frumos gest ca DeepMind a publicat acel material in Nature in care a descris pe scurt tehnologia si ideile folosite pentru realizarea AlphaGo. Dar parerea mea e ca e doar de suprafata si insuficient pentru a ajunge la performanta realizata de echipa de la DeepMind. In plus numai echipa prezentata in Coreea la sfarsitul meciului parea ca numara cel putin 15 oameni. Si presupun ca nu erau toti. Cu tot respectul pentru efortul lui Rémi Coulom si echipa lui dar ma astept sa fie diferente mari de capacitati... in multe sensuri.
