Learning from Integral Losses in Physics Informed Neural Networks

2 code implementations27 May 2023 Ehsan Saleh, Saba Ghaffari, Timothy Bretl, Luke Olson, Matthew West

Our numerical results confirm the existence of the aforementioned bias in practice, and also show that our proposed delayed target approach can lead to accurate solutions with comparable quality to ones estimated with a large number of samples.

Robust Model-Based Optimization for Challenging Fitness Landscapes

1 code implementation23 May 2023 Saba Ghaffari, Ehsan Saleh, Alexander G. Schwing, Yu-Xiong Wang, Martin D. Burke, Saurabh Sinha

Protein design, a grand challenge of the day, involves optimization on a fitness landscape, and leading methods adopt a model-based approach where a model is trained on a training set (protein sequences and fitness) and proposes candidates to explore next.

Truly Deterministic Policy Optimization

1 code implementation30 May 2022 Ehsan Saleh, Saba Ghaffari, Timothy Bretl, Matthew West

In this paper, we present a policy gradient method that avoids exploratory noise injection and performs policy search over the deterministic landscape.
