Rethinking the Starting Point: Collaborative Pre-Training for Federated Downstream Tasks

AAAI 2025technical

A few recent studies have shown the benefits of using centrally pre-trained models to initialize federated learning (FL). However, existing methods do not generalize well when faced with an arbitrary set of downstream FL tasks. Specifically, they often (i) achieve limited accuracy, especially with u…

Unlocking the Potential of Model Calibration in Federated Learning

ICLR 2025poster

Over the past several years, various federated learning (FL) methodologies have been developed to improve model accuracy, a primary performance metric in machine learning. However, to utilize FL in practical decision-making scenarios, beyond considering accuracy, the trained model must also have a r…

Learning to Rank Visual Stories From Human Ranking Data

ACL 2022long

Visual storytelling (VIST) is a typical vision and language task that has seen extensive development in the natural language generation research domain. However, it remains unclear whether conventional automatic evaluation metrics for text generation are applicable on VIST. In this paper, we present…
