RoseNet: Predicting Energy Metrics of Double InDel Mutants Using Deep Learning

no code implementations20 Oct 2023 Sarah Coffland, Katie Christensen, Filip Jagodzinski, Brian Hutchinson

We explore and present how RoseNet is able to emulate the exhaustive data set using deep learning methods, and show to what extent it can predict Rosetta metrics for unseen mutant sequences with two InDels.

DiffESM: Conditional Emulation of Earth System Models with Diffusion Models

no code implementations23 Apr 2023 Seth Bassetti, Brian Hutchinson, Claudia Tebaldi, Ben Kravitz

Earth System Models (ESMs) are essential tools for understanding the impact of human actions on Earth's climate.

Fine-Grained Classroom Activity Detection from Audio with Neural Networks

1 code implementation29 Jul 2021 Eric Slyman, Chris Daw, Morgan Skrabut, Ana Usenko, Brian Hutchinson

We obtain strong results on the new fine-grained task and state-of-the-art on the 4-way task: our best model obtains frame-level error rates of 6. 2%, 7. 7% and 28. 0% when generalizing to unseen instructors for the 4-way, 5-way, and 9-way classification tasks, respectively (relative reductions of 35. 4%, 48. 3% and 21. 6% over a strong baseline).
