Kernel-Based Least Squares Policy Iteration for Reinforcement Learning
TLDR
We present a kernel-based least squares policy iteration (KLSPI) algorithm for reinforcement learning (RL) in large or continuous state spaces, which can be used to realize adaptive feedback control of uncertain dynamic systems. Expand

Beyond random walk and metropolis-hastings samplers: why you should not backtrack for unbiased graph sampling
TLDR
In this paper, we propose non-backtracking random walk with re-weighting (NBRW-rw) and MH algorithm with delayed acceptance (MHDA) which are theoretically guaranteed to achieve, at almost no additional cost, not only unbiased graph sampling but also higher efficiency (smaller asymptotic variance of the resulting unbiased estimators) than the SRW and the MH algorithm, respectively.
