The author explores the challenges and solutions in federated transfer learning by integrating transfer learning into federated learning. They address issues such as data heterogeneity, system heterogeneity, incremental data, labeled data scarcity, and model heterogeneity.
Tiivistelmä
The content delves into the complexities of federated transfer learning, highlighting challenges like prior shift, covariate shift, feature concept shift, label concept shift, quantity shift, feature space heterogeneity, label space heterogeneity, system heterogeneity, incremental data, model adaptive FTL, semi-supervised FTL, and unsupervised FTL. Strategies for addressing these challenges are discussed through both data-based and model-based approaches.
