New Theory Explains Neural Network Generalization Beyond Overfitting
This research proposes a new theoretical framework to explain why neural networks can generalize effectively even when over-parameterized. It links this phenomenon to a phase transition in the training process, marked by broken ergodicity and a breakdown of the fluctuation-dissipation theorem.
PoE-Bridge Boosts Diffusion Language Model Speed and Accuracy
A new decoding framework called PoE-Bridge significantly improves the generation speed and accuracy of Diffusion Language Models (DLMs) by bridging the performance gap with autoregressive models.
Graph Convolutional Attention Improves Graph Denoising and Diffusion
Researchers introduce Graph Convolutional Attention (GCA), a novel attention mechanism that leverages the input graph spectrum to significantly improve graph denoising and diffusion models. GCA addresses the limitations of standard linear attention by learning a more adaptive spectral denoising filter, leading to better performance on diverse graph datasets.
