Aligning Few-Step Generative Models by Amortizing Sample-based Variational Inference
Several recent research papers explore advancements in generative models, focusing on improving their efficiency, evaluability, and alignment. One paper proposes a new framework for weighted sampling using score-based generative models, achieving significant speedups. Another theoretical framework addresses the statistical evaluability of generative models, distinguishing between metrics that can be reliably estimated from finite samples and those that cannot. Other research introduces methods for parameter-efficient generative modeling, calibrating models to distributional constraints, and aligning few-step generative models using sample-based variational inference.
