Average Case Robustness

Average-case robustness in machine learning assesses the consistency of model predictions across a neighborhood of input data points, offering a more nuanced perspective than traditional worst-case adversarial robustness analysis. Current research focuses on developing efficient methods to estimate average-case robustness, particularly for deep learning models, and benchmarking model performance against diverse attack types and strengths. This research is crucial for improving the reliability and trustworthiness of machine learning systems in real-world applications, where models must handle variations and uncertainties in input data. Understanding the interplay between model architecture (depth, width, initialization), training methods, and average-case robustness is a key area of ongoing investigation.
