Personalized Federated Learning under Local Supervision

ICCV 2025poster

A crucial issue in federated learning is the heterogeneity of data across clients, which may lead to model divergence, eventually deteriorating the model performance. Personalized federated learning (pFL) has been shown to be an effective approach to addressing data heterogeneity in federated learni…

Voronoi-grid-based Pareto Front Learning and Its Application to Collaborative Federated Learning

ICML 2025poster

Multi-objective optimization (MOO) exists extensively in machine learning, and aims to find a set of Pareto-optimal solutions, called the Pareto front, e.g., it is fundamental for multiple avenues of research in federated learning (FL). Pareto-Front Learning (PFL) is a powerful method implemented us…

Free-Rider and Conflict Aware Collaboration Formation for Cross-Silo Federated Learning

NeurIPS 2024poster

Federated learning (FL) is a machine learning paradigm that allows multiple FL participants (FL-PTs) to collaborate on training models without sharing private data. Due to data heterogeneity, negative transfer may occur in the FL training process. This necessitates FL-PT selection based on their dat…

A Rotation Invariant HOG Descriptor for Tire Pattern Image Classification

ICASSP 2019accepted

Texture feature is important in describing tire pattern image which provides useful clue in solving crime cases and traffic accidents. In this paper, we propose a novel texture feature extraction method based on HOG (Histogram of Oriented Gradient) and dominant gradient (DG) in tire pattern images,…
