Google's AlphaGo program has already won the best-of-five match against Lee Sedol. But Sedol now has ensured it won't be a clean sweep by getting a victory in on game four.
Lee Sedol has lost three games in a row to Google's AlphaGo program, which means the program has officially defeated the human. Lee said the pressure was intense, and he felt "powerless."
This game lacked some of the hard-hitting exchanges of the first, with several analysts agreeing that in Round 2, Lee Sedol took a more cautious approach while AlphaGo showed more creativity.
"They were neck-and-neck for its entirety, in a game filled with complex fighting," according to a recap. The five-game match will continue through the weekend.
