End-to-End Refinement Guided by Pre-trained Prototypical Classifier

2018 · arXiv (Cornell University)

Many real-world tasks involve identifying patterns from data satisfying background or prior knowledge. In domains like materials discovery, due to the flaws and biases in raw experimental data, the identification of X-ray diffraction patterns (XRD) …

Bootstrap Advantage Estimation for Policy Optimization in Reinforcement Learning

2022 · arXiv (Cornell University)

This paper proposes an advantage estimation approach based on data augmentation for policy optimization. Unlike using data augmentation on the input to learn value and policy function as existing methods use, our method uses data …
