Abstract : This report describes an exploration criterion that attempts to minimize the error of a learner by minimizing its estimated squared bias. The author describes experiments with locally-weighted regression on two simple kinematics problems, and observed that this "bias-only" approach outperforms the more common "variance-only" exploration approach, even in the presence of noise.
