Welcome to the DeLTA Lab

Research Overview

1. We integrate AI methods with physics knowledge.

a) We build LLMs for autoformalization, program synthesis, and reasoning on PDE problems [1, 2, 3].

b) We introduce physics into data-driven fluids modeling and reconstruction [4, 5, 6, 7, 8].

2. We develop principled deep learning methods [9, 10, 11, 12] inspired by deep learning theory.

3. We are broadly interested in LLM [13, 14, 15], computer vision [16, 17], model efficiency [18, 19], self-supervised learning [20, 21], automated machine learning (AutoML) [22], etc.
