Center node: "should one minimize the expected bellman residual or maximize the mean value"
  Abstract: We study reinforcement learning from an optimization perspective. We consider maximizing the mean value (the predominant approach in policy search) and minimizing the expected Bellman residual (the Bellman residual being prevalent in approximate dynamic programming). For doing so, we introduce a new approach that consists in minimizing the mean residual $\nu(T_* v_\pi - v_\pi)$ for a class of parameterized policies. We prove that this method enjoys a performance bound that is better than the sole known bound for maximizing the mean value and that matches the best known bounds in approximate dynamic programming. We also conduct experiments on randomly generated generic Markov decision processes to compare both approaches empirically. It appears that maximizing the mean value is much more efficient, and that the Bellman residual is actually not a such good proxy for optimizing a value function. This suggests to envision maximizing the mean value for designing new reinforcement learning approaches, and that much remains to be done regarding its theoretical analysis.
