Reviews: A Kernel Loss for Solving the Bellman Equation

Originality: The derivation of the loss function is original; the resulting loss function has some close similarities with the coupled formulation of LSTD, which should be discussed. Quality: The claims seem to be accurate (I briefly verified the proofs of Theorem 3.1, Proposition 3.3, Proposition 3.4; I did not verify Theorem 3.2 and Corollary 3.5). Clarity: The paper is well-written and clear. Significance: The addressed problem is important; the insights are also useful. SUMMARY: The paper addresses the problem of designing a new loss function for RL.
