A Federated Learning Benchmarking Framework

Federated Learning Benchmark Framework

Website | Paper

A strategic framework for systematically benchmarking federated learning algorithms across diverse datasets and client distributions. Built for researchers and practitioners to make informed algorithm selection decisions based on rigorous comparative analysis.

Strategic Overview

FLBenchmark provides a comprehensive ecosystem for evaluating federated learning strategies in realistic scenarios. Our framework enables:

• Strategic Algorithm Selection: Identify optimal algorithms for specific data distributions and application constraints
• Performance Trade-off Analysis: Evaluate critical trade-offs between accuracy, communication efficiency, and privacy preservation
• Heterogeneity Impact Assessment: Measure how different heterogeneity factors affect algorithm performance
• Systematic Comparison Methodology: Ensure fair, reproducible comparisons between federated optimization approaches

Installation

pip install fedbench
