Stochastic Forward-Forward Learning through Representational Dimensionality Compression

NeurIPS 2025poster

The Forward-Forward (FF) learning algorithm provides a bottom-up alternative to backpropagation (BP) for training neural networks, relying on a layer-wise "goodness" function with well-designed negative samples for contrastive learning. Existing goodness functions are typically defined as the sum o…

Accelerating Score-Based Generative Models with Preconditioned Diffusion Sampling

ECCV 2022poster

"Score-based generative models (SGMs) have recently emerged as a promising class of generative models. However, a fundamental limitation is that their inference is very slow due to a need for many (e.g., 2000) iterations of sequential computations. An intuitive acceleration method is to reduce the s…
