UT Professor Peter Stone is features in this article from the AAAS Science Magazine. From the article: "[Todd] Hester and Peter Stone, a computer scientist at the University of Texas in Austin, developed a new algorithm, Targeted Exploration with Variance-And-Novelty-Intrinsic-Rewards (TEXPLORE-VENIR), that relies on a technique called reinforcement learning. In reinforcement learning, a program tries something, and if the move brings it closer to some ultimate goal, such as the end of a maze, it receives a small reward and is more likely to try the maneuver again in the future. DeepMind has used reinforcement learning to allow programs to master Atari games and the board game Go through random experimentation. But TEXPLORE-VENIR, like other curiosity algorithms, also sets an internal goal for which the program rewards itself for comprehending something new, even if the knowledge doesn’t get it closer to the ultimate goal."
