Researchers have developed a new method called Inner Momentum (IM) to improve the accuracy of differentially private machine learning models, particularly for tasks like fine-tuning GPT-2. This technique addresses issues where gradient clipping, a standard privacy measure, can distort the model's geometric properties. By averaging gradients over a short history of recent models before clipping, DP-Muon-IM reduces this distortion and shows improved performance on benchmarks like BLEU and ROUGE-L compared to the original DP-Muon method.
