New algorithm bridges average and discounted TD learning theory

Researchers have developed a new algorithm for policy evaluation in average-reward settings, addressing theoretical challenges where standard analyses are complicated by the Bellman operator not being contractive. This novel method uses sampling from two Markovian trajectories to guarantee convergence to a projected Bellman equation solution. The algorithm's convergence analysis applies to both linear function approximation and tabular settings without dimension-dependent terms, and it improves sample complexity from quartic to quadratic scaling, matching the efficiency of discounted settings.
