Pre par godina je neki japanski doktor automatike i robotike držao gostujuće predavanje kod nas, TL;DR u pitanju je psihološki efekat, ljudi (iako sasvim svesni da je u pitanju mašina a ne živo biće) mnogo bolje "sarađuju" i prihvataju kao ispomoć robote humanoidnog oblika iako bi se za određene poslove svakako lakše napravio efikasniji robot drugačijeg oblika i kretanja.

Izgleda da smo svi rasisti i da postoji više slojeva rasizma!

ne znam sto su ljudi toliko optereceni humanoidnim izgledom robota kad postoje efikasniji nacini kretanja:)

sem onog što reče Vudu, ne pravi boston dynamics to jer vole voltrona, nego darpa oce all terrain robotsku mazgu (krajnje desno na pocetku clipa) i eventualno human replacement combat robota/drona, al skroz reLANo =o)

Ali zamisli samo, humanoidni robot prepisuje antibiotike za kijavicu nadžak-babama i empatično klima glavom na priče o kretanju cena esencije i tegli za turšiju a ti glumiš House-a i dijagnostikuješ samo kad se AI zbaguje!  A i robota mogu da izbodu koliko hoće puta i nikom ništa :tf:

znam na sta si mislio :D nego mi postavka malo nije na mestu. Mislim, u samom startu je humanoidno kretanje neefikasno, tako da tu ima milion i jedan nacin da ga ucinis efikasnijim, ali opet sve pocinje od toga da ga prvo priblizis zemlji. Tek posle toga ulazi u pricu dal ces da mu stavis gusenice, papke, siljke il nesto peto. U smislu da ce ta "macka" biti efikasnija i na tockicima sa kolica iz supermarketa nego neko humanoidno sranje sa proizvoljnim osloncem. Naravno, ovo su samo moja dva centa, a bilo bi lepo da dule il neko ko je upucen u ovu problematiku da pravo stanje stvari

Nije bas robot, ali je znacajan korak za nauku - ne znam gde da smestim. Potreban nam je topic za novosti

Naime juce je Googlov AlphaGo pobedio legendarnu sampionku Lee Se-Dol u korejskoj igri "Go". Danas je zablezio jos jednu pobedu i trenutni skor je 2-0 za Ai razvijen i naucen putem neuralnih mreza. Mozda ne zvuci kao nesto posebno, obzirom da odavno imamo programe koji su pobedili velemajstore saha, -  ali jeste. Sahovski programi se oslanjanju na "brute computing force", milione memorisanih partija za trazenje odgovorajuceg poteza, gde covek jednostavno ne moze da parira .... to se jednostavno ne moze primeniti na Go.

Igrace se jos 3 meca, ali cak i da Lee pobedi to ne umanjuje ovaj neverovatan milestone u istoriji vestacke inteligencije. Prvo, niko nije ocekivao da ce AlphaGo pobediti. Drugo, cak i da se pripise sreci/ljudskoj gresci prva pobeda, potezi koje je mreza napravila u drugoj partiji su sve osim ocekivani. 

"Yesterday I was surprised but today it's more than that — I am speechless," said Lee in the post-game press conference. "I admit that it was a very clear loss on my part. From the very beginning of the game I did not feel like there was a point that I was leading." 

"We're very pleased that AlphaGo played some quite surprising and beautiful moves, according to the commentators, which was amazing to see." 

 

The close nature of the game appears to offer validation of AlphaGo's evaluative ability, the main roadblock to proficiency for previous Go programs. Hassabis says that AlphaGo was confident in victory from the midway point of the game, even though the professional commentators couldn't tell which player was ahead. 

But AlphaGo could also open up new avenues for the game. Members of the Go community are as stunned with the inventive, aggressive way AlphaGo won as the fact that it did at all. "There were some moves at the beginning — what would you say about those three moves on the right on the fifth line?" American Go Association president Andy Okun asked VP of operations Andrew Jackson, who also happens to be a Google software engineer, at the venue following the match. "As it pushes from behind?" Jackson replied. "If I made those same moves…" Okun continued. "Our teachers would slap our wrists," Jackson agreed. "They’d smack me!" says Okun. "You don’t push from behind on the fifth line!"

"We’re absolutely in shock," said Jackson. "There’s a real question, though. We’ve got this established Go orthodoxy, so what’s this going to reveal to us next? Is it going to shake things up? Are we going to find these things that we thought were true — these things you think you know and they just ain’t so?"

 

Potezi koje je program odigrao nikada nisu do sada bili koristeni. Ako nekoga interesuje sledeci mecevi prenose se live na:
