Generalization Guarantees for Representation Learning via Data-Dependent Gaussian Mixture Priors

ICLR 2025spotlight

We establish in-expectation and tail bounds on the generalization error of representation learning type algorithms. The bounds are in terms of the relative entropy between the distribution of the representations extracted from the training and "test'' datasets and a data-dependent symmetric prior, i…

Tighter CMI-Based Generalization Bounds via Stochastic Projection and Quantization

NeurIPS 2025oral

In this paper, we leverage stochastic projection and lossy compression to establish new conditional mutual information (CMI) bounds on the generalization error of statistical learning algorithms. It is shown that these bounds are generally tighter than the existing ones. In particular, we prove that…

Lessons from Generalization Error Analysis of Federated Learning: You May Communicate Less Often!

ICML 2024poster

We investigate the generalization error of statistical learning models in a Federated Learning (FL) setting. Specifically, we study the evolution of the generalization error with the number of communication rounds $R$ between $K$ clients and a parameter server (PS), i.e. the effect on the generaliza…

Minimum Description Length and Generalization Guarantees for Representation Learning

NeurIPS 2023poster

A major challenge in designing efficient statistical supervised learning algorithms is finding representations that perform well not only on available training samples but also on unseen data. While the study of representation learning has spurred much interest, most existing such approaches are heu…

Rate-Distortion Theoretic Bounds on Generalization Error for Distributed Learning

NeurIPS 2022accept

In this paper, we use tools from rate-distortion theory to establish new upper bounds on the generalization error of statistical distributed learning algorithms. Specifically, there are $K$ clients whose individually chosen models are aggregated by a central server. The bounds depend on the compress…

Heavy Tails in SGD and Compressibility of Overparametrized Neural Networks

NeurIPS 2021poster

Neural network compression techniques have become increasingly popular as they can drastically reduce the storage and computation requirements for very large networks. Recent empirical studies have illustrated that even simple pruning strategies can be surprisingly effective, and several theoretical…
