Consistency is Key to Image Denoising

Without noise, image processing and pattern recognition would be a fait accompli! Image denoising remains a fundamental challenge in practical image processing applications. Deep neural networks (DNNs) have set new performance benchmarks over classical techniques by using supervised learning to predict either the clean...

Finite-Time Convergence of Single-Trajectory Chi-Square Robust Q-Learning With Linear Function Approximation

This work addresses obstacles through a variational reformulation of the robust Bellman target and a blockwise frozen-target scheme, and establishes a finite-time error bound relative to the optimal robust Q-function for every $\gamma\in(0,1)$.
