AugLoss: A Robust Augmentation-based Fine Tuning Methodology

no code implementations5 Jun 2022 Kyle Otstot, Andrew Yang, John Kevin Cava, Lalitha Sankar

As a step towards addressing both problems simultaneously, we introduce AugLoss, a simple but effective methodology that achieves robustness against both train-time noisy labeling and test-time feature distribution shifts by unifying data augmentation and robust loss functions.

Towards Conditional Generation of Minimal Action Potential Pathways for Molecular Dynamics

1 code implementation28 Nov 2021 John Kevin Cava, John Vant, Nicholas Ho, Ankita Shukla, Pavan Turaga, Ross Maciejewski, Abhishek Singharoy

In this paper, we utilized generative models, and reformulate it for problems in molecular dynamics (MD) simulation, by introducing an MD potential energy component to our generative model.

A Tunable Loss Function for Robust Classification: Calibration, Landscape, and Generalization

1 code implementation5 Jun 2019 Tyler Sypherd, Mario Diaz, John Kevin Cava, Gautam Dasarathy, Peter Kairouz, Lalitha Sankar

We introduce a tunable loss function called $\alpha$-loss, parameterized by $\alpha \in (0,\infty]$, which interpolates between the exponential loss ($\alpha = 1/2$), the log-loss ($\alpha = 1$), and the 0-1 loss ($\alpha = \infty$), for the machine learning setting of classification.
