Enhancing Dual-Encoders with Question and Answer Cross-Embeddings for Answer Retrieval

2021

Dual-Encoders is a promising mechanism for answer retrieval in question answering (QA) systems. Currently most conventional Dual-Encoders learn the semantic representations of questions and answers merely through matching score. Researchers proposed to introduce the QA …

A clustering federated learning algorithm based on three-layer structure

2023

Federated learning is a new distributed machine learning method. Decentralized clients can train data locally, and multi-party machine learning can be implemented efficiently by aggregating clients to update models through a central server. Therefore, federated …
