[Paper] Conflict-Aware Harmonized Rotational Gradient for Multiscale Kinetic Regimes

Summary

This paper introduces HRGrad, a novel harmonized rotational gradient method designed to tackle complex multiscale time-dependent kinetic problems. These problems are challenging due to parameters transitioning between microscopic and macroscopic physics, often leading to "gradient conflicts" that hinder multi-task learning. HRGrad aims to overcome these conflicts, enabling simultaneous solutions across various asymptotic regions.
