Summary

This research introduces a novel trilevel optimization framework, F$^2$CTO, for robust coreset selection in distributed edge networks, addressing computational and storage challenges in IoT data. It is the first method for distributed robust coreset selection and trilevel optimization with level-wise constraints, demonstrating effectiveness in continual learning.

The proliferation of IoT devices generates vast amounts of data across distributed networks, posing significant challenges for model training due to computational overhead and storage limitations. Coreset selection, which involves choosing a representative subset of data, is crucial for efficiency. This paper addresses the complex problem of robust coreset selection in a distributed, privacy-sensitive environment. Researchers have developed a new framework called F$^2$CTO (Federated First-order Constrained Trilevel Optimization). This framework is designed to handle the hierarchical dependencies between coreset selection, robust optimization, and distributed learning, formulating it as a trilevel optimization problem with specific constraints at each level. F$^2$CTO integrates a hierarchical composite value-function reformulation with a distributed alternating projected gradient algorithm. It is presented as the first method to tackle distributed robust coreset selection and the first distributed optimization approach for trilevel problems with level-wise constraints, showing strong performance in continual learning scenarios.

Why it matters

Professionals dealing with large-scale, distributed data in IoT or edge computing can leverage this framework to significantly reduce training costs and improve model robustness while respecting data privacy.

Dual Teachers Improve Adversarial Robustness and Accuracy.

This work extends Information Bottleneck Distillation (IBD) by introducing a "clean teacher" alongside a robust teacher to improve the robustness/accuracy tradeoff against adversarial attacks. The proposed method transfers features from both teachers to a student model, achieving better clean accuracy while maintaining adversarial robustness, outperforming original IBD and competing with state-of-the-art approaches.
