FedPrompt: Communication-Efficient and Privacy Preserving Prompt Tuning in Federated Learning

Zhao, Haodong, Du, Wei, Li, Fangqi et al.

Understand

Federated learning (FL) has enabled global model training on decentralized data in a privacy-preserving way by aggregating model updates.

  • However, for many natural language processing (NLP) tasks that utilize pre-trained language models (PLMs) with large numbers of parameters, there are considerable communication costs associated with FL.
  • Recently, prompt tuning, which tunes some soft prompts without modifying PLMs, has achieved excellent performance as a new learning paradigm.
  • Therefore we want to combine the two methods and explore the effect of prompt tuning under FL.
