Implicit Bias of Spectral Descent and Muon on Multiclass Separable Data

NeurIPS 2025spotlight

Different gradient-based methods for optimizing overparameterized models can all achieve zero training error yet converge to distinctly different solutions inducing different generalization properties. We provide the first complete characterization of implicit optimization bias for p-norm normalized…

POL-VIO: A Visual Inertial Odometry With Polarization Skylight Compass in Challenge Environment

RA-L 2025

Visual-inertial odometry with low-cost visual and inertial sensors can provide accurate navigation results in GNSS-denied environment. However, the mainstream methods currently suffer from the inevitable accumulation of position and heading errors over long-term operation. Inspired by the compound e

BiSLS/SPS: Auto-tune Step Sizes for Stable Bi-level Optimization

NeurIPS 2023poster

The popularity of bi-level optimization (BO) in deep learning has spurred a growing interest in studying gradient-based BO algorithms. However, existing algorithms involve two coupled learning rates that can be affected by approximation errors when computing hypergradients, making careful fine-tunin…
