Uniform Stability
Uniform stability, a measure of an algorithm's sensitivity to changes in the training data, is a crucial concept in machine learning, aiming to guarantee generalization performance and robustness. Current research focuses on establishing uniform stability bounds for various algorithms, including stochastic gradient descent and its compositional variants, and exploring its application in challenging scenarios like adversarial training and federated learning, often within the context of specific model architectures such as neural networks and physics-informed neural networks. These investigations are vital for improving the reliability and trustworthiness of machine learning models by providing theoretical guarantees on their generalization ability and resistance to noise and adversarial attacks.
