We propose an off-policy evaluation method for finite-horizon MDPs with rewards missing not at random. Our approach uses a reward-dependent propensity model and a bridge function to recover conditional mean rewards without modeling the MNAR mechanism, achieving consistency and finite-sample error bounds. Experiments on simulated and MIMIC-III Sepsis data show superior performance over existing methods.

A single ReLU recurrent neural network with fixed weights and hidden dimension can uniformly approximate any continuous function on [-1,1] as its runtime increases. This is achieved via a new model, the Turing machine with neural units (TMNU), which balances algorithmic flexibility with bounded simulation by RNNs. The convergence rates match polynomial approximation rates, and minimax lower bounds confirm that runtime is an essential, unavoidable resource.
QCPIKAN is the first quantum-classical physics-informed Kolmogorov-Arnold network designed to solve partial differential equations.
