On the Memorization of Consistency Distillation for Diffusion Models
Bingqing Jiang, Difan Zou
Diffusion models are central to modern generative modeling, and understanding how they balance memorization and generalization is critical for reliable deployment. Recent work has…
Learning under Quantization for High-Dimensional Linear Regression
Dechen Zhang, Junwei Su, Difan Zou
The use of low-bit quantization has emerged as an indispensable technique for enabling the efficient training of large-scale models. Despite its widespread empirical success, a rig…
On the Limitation and Experience Replay for GNNs in Continual Learning
Junwei Su, Difan Zou, Chuan Wu
Continual learning seeks to empower models to progressively acquire information from a sequence of tasks. This approach is crucial for many real-world systems, which are dynamic an…
Improving Implicit Regularization of SGD with Preconditioning for Least Square Problems
Junwei Su, Difan Zou, Chuan Wu
Stochastic gradient descent (SGD) exhibits strong algorithmic regularization effects in practice and plays an important role in the generalization of modern machine learning. Howev…
