Facebook improves AI by sending ‘tourist bots’ to a virtual NYC

A recent experiment by Facebook pitted humans against AI to see which was better at helping another robot to navigate a (virtual) walk around an area of Hells Kitchen in New York. The bot had to describe its location using natural language ("I can see the bank on the corner"). Although the AI only scored 50% in this mode, when using "symbols" instead, it was able to beat humans 87.08% to 76.74%. The two AI were able to communicate far more efficiently than humans could. But as a test for their new "MASC (Masked Attention for Spatial Convolution)" model, it was a success.
