Abstract: 

Machine learning model training often require data from multiple parties. However, in some cases, data owners cannot or are not willing to share their data due to legal or privacy constraints but would still like to benefit from training a model jointly with multiple parties. To this end, federated learning (FL) has emerged as an alternative way to do collaborative model training without sharing the training data. Such collaboration leads to more accurate and performant models than any party owning a partial set of all the data sources could hope to learn in isolation.

In this paper, we study the impact of resource (e.g., CPU, memory, and network resources) and data (e.g., training dataset sizes) heterogeneity on the training time of FL. Then, we discuss the research problems and their challenges involved in taming such resource and data heterogeneity in FL systems.
