Query: Self-correcting Q-Learning   The Q-learning algorithm is known to be affected by the maximization bias,
i.e. the systematic overestimation of action values, an important issue that
has recently received renewed attention. Double Q-learning has been proposed as
an efficient algorithm to mitigate this bias. However, this comes at the price
of an underestimation of action values, in addition to increased memory
requirements and a slower convergence. In this paper, we introduce a new way to
address the maximization bias in the form of a "self-correcting algorithm" for
approximating the maximum of an expected value. Our method balances the
overestimation of the single estimator used in conventional Q-learning and the
underestimation of the double estimator used in Double Q-learning. Applying
this strategy to Q-learning results in Self-correcting Q-learning. We show
theoretically that this new algorithm enjoys the same convergence guarantees as
Q-learning while being more accurate. Empirically, it performs better than
Double Q-learning in domains with rewards of high variance, and it even attains
faster convergence than Q-learning in domains with rewards of zero or low
variance. These advantages transfer to a Deep Q Network implementation that we
call Self-correcting DQN and which outperforms regular DQN and Double DQN on
several tasks in the Atari 2600 domain.
