Researchers have developed a new framework for parameter-efficient fine-tuning of large pre-trained models that leverages the geometric structure of low-rank manifolds. This approach utilizes Stein Variational Gradient Descent (SVGD) on the Stiefel manifold, allowing for uncertainty quantification and more calibrated adapters. Experiments indicate that this geometry-aware SVGD method achieves higher prediction accuracy compared to existing methods operating in Euclidean space. AI
