Facebook's open-source Go bot can now beat professional players

Go is the go-to game for machine learning researchers. It's what Google's DeepMind team famously used to show off its algorithms, and Facebook, too, recently announced that it was building a Go bot of its own. As the team announced at the company's F8 developer conference today, the ELF OpenGo bot has now achieved professional status after winning all 14 games it played against a group of top 30 human Go players recently. "We salute our friends at DeepMind for doing awesome work," Facebook CTO Mike Schroepfer said in today's keynote. "But we wondered: Are there some unanswered questions? What else can you apply these tools to."
