NLP Inspired Training Mechanics For Modeling Transient Dynamics

4 Nov 2022  ·  Lalit Ghule, Rishikesh Ranade, Jay Pathak ·

In recent years, Machine learning (ML) techniques developed for Natural Language Processing (NLP) have permeated into developing better computer vision algorithms. In this work, we use such NLP-inspired techniques to improve the accuracy, robustness and generalizability of ML models for simulating transient dynamics. We introduce teacher forcing and curriculum learning based training mechanics to model vortical flows and show an enhancement in accuracy for ML models, such as FNO and UNet by more than 50%.
