Abstract: 

Amidst increasing data volumes, addressing large-scale machine learning challenges in environments characterized by inherent variability is crucial. Such variability impacts data collection, format, quality, computational capacity, and connectivity within cyber-physical systems, thereby shaping the development of resilient machine learning models across a wide array of high-impact applications.  In dynamic environments, variability can manifest in several ways: (1) evolving network settings, with continuously changing topologies and reliability; (2) heterogeneous data sources and formats, featuring diverse data sample resources and formats as supplementary information; (3) limited computational power, where constraints and disparities in computational capacity hinder extensive model training and exacerbate unfairness.

This presentation will focus on environmental variability, highlighting recent efforts to develop theoretically robust machine learning approaches addressing these challenges with provable guarantees. The goal is to improve learning models by adapting them to adverse environments. We will examine three core methodological directions—mobilizing, transferring, and adaptive morphing—alongside case studies, including federated learning and mobile health.
