![]() ![]() They invited me to join in, squeezing one more stool around the table. “We celebrate by drinking!” one man at the table said, before I could finish my explanation. I explained to them I was a foreign journalist, trying to tell the story of how they celebrate the New Year. The men smoked and ate at the same time, throwing tangerine peel and the hulls of sunflower seeds on the ground. We walked by a raucous group of young adults, sat shoulder-to-shoulder on tiny stools around a short table packed to the brim with food. Most people I met asked me to call them “Xiao Yang” or “Little Yang.” Almost everyone shares the surname Yang, except for a few families with the last name Li or Wang. People here say they’re all relatives, and the village is like one big family. It’s the Lunar New Year, and during the daytime, the doors are rarely closed. A wall of lush green trees and bamboo surround this village of about 1,000 people, who’ve lived in wooden homes with gray-tiled roofs for centuries. Designed to help unearth even more strategic moves, the summit included various game formats such as pair Go, team Go, and a match with the world’s number one player Ke Jie.In China’s southern Guizhou province, there’s a tiny village in the southeast corner, nestled deep within the mountains, called Dali. The five-day festival created an opportunity to explore the mysteries of Go in a spirit of mutual collaboration with the country’s top players. Four months later, AlphaGo took part in the Future of Go Summit in China, the birthplace of Go. This online player achieved 60 straight wins in time-control games against top international players. In January 2017, we revealed an improved, online version of AlphaGo called Master. Players of all levels have extensively examined these moves ever since. During the games, AlphaGo played several inventive winning moves, several of which - including move 37 in game two - were so surprising that they upended hundreds of years of wisdom. This was the first time a computer Go player had ever received the accolade. The game earned AlphaGo a 9 dan professional ranking, the highest certification. This landmark achievement was a decade ahead of its time. AlphaGo's 4-1 victory in Seoul, South Korea, on March 2016 was watched by over 200 million people worldwide. AlphaGo won the first ever game against a Go professional with a score of 5-0.ĪlphaGo then competed against legendary Go player Mr Lee Sedol, the winner of 18 world titles, who is widely considered the greatest player of the past decade. In October 2015, AlphaGo played its first match against the reigning three-time European Champion, Mr Fan Hui. ![]() AlphaGo went on to defeat Go world champions in different global arenas and arguably became the greatest Go player of all time. This process is known as reinforcement learning. ![]() Over time, AlphaGo improved and became increasingly stronger and better at learning and decision-making. Then we had it play against different versions of itself thousands of times, each time learning from its mistakes. ![]() We introduced AlphaGo to numerous amateur games to help it develop an understanding of reasonable human play. The other neural network, the “value network”, predicts the winner of the game. One neural network, the “policy network”, selects the next move to play. These neural networks take a description of the Go board as an input and process it through a number of different network layers containing millions of neuron-like connections. We created AlphaGo, a computer program that combines advanced search tree with deep neural networks. To capture the intuitive aspect of the game, we needed a new approach. ![]()
