Abstract

In the landscape of TD algorithms, the Q(, ) algorithm is an algorithm with the ability to perform a multistep backup in an online manner while also successfully unifying the concepts of sampling with using the expectation across all actions for a state. [0, 1] indicates the extent to which sampling is used. Selecting the value of can be based on characteristics of the current state rather than having a constant value or being time based. This report explores the viability of such a TD-error based scheme.
