CTBench: A Library and Benchmark for Certified Training
Keywords: certified training, benchmark, open-source library
TL;DR: We develop a library unifying certified training algorithms, achieve SOTA universally by correcting exsiting implementation mistakes, gain new insights and point out future work direction.
Abstract: Training certifiably robust neural networks is an important but challenging task. While many algorithms for (deterministic) certified training have been proposed, they are often evaluated on different training schedules, certification methods, and systematically under-tuned hyperparameters, making it difficult to compare their performance. To address this challenge, we introduce CTBench, a unified library and a high-quality benchmark for certified training that evaluates all algorithms under fair settings and systematically tuned hyperparameters. We show that (1) almost all algorithms in CTBench surpass the corresponding reported performance in literature in the magnitude of algorithmic improvements, thus establishing new state-of-the-art, and (2) the claimed advantage of recent algorithms drops significantly when we enhance the outdated baselines with a fair training schedule, a fair certification method and well-tuned hyperparameters. Based on CTBench, we provide insights into the current state of certified training and suggest future research directions. We are confident that CTBench will serve as a benchmark and testbed for future research in certified training.
