OpenAI has developed a new method called Private Aggregation of Teacher Ensembles (PATE) to enhance privacy for deep learning models trained on sensitive data. PATE combines multiple 'teacher' models, each trained on separate private datasets, to train a final 'student' model. This student model learns from the aggregated, noisy predictions of the teachers, ensuring that no single teacher or dataset dictates the outcome and providing strong privacy guarantees, even against adversaries inspecting the model's internals. The approach is broadly applicable to various model types, including deep neural networks, and has demonstrated state-of-the-art privacy-utility trade-offs on benchmark datasets. AI
