Federated learning, differential privacy, and privacy-preserving machine learning. We cover how models train across devices and institutions without centralizing data, what privacy guarantees actually cost in accuracy, and the benchmarks and frameworks shaping the field, always traced back to the original research.
Federated recommenders drift apart when clients simply average parameters. AlignFedRec shares item similarity matrices instead, aligning structure rather than embeddings.
