Structural Uncertainty

Structural uncertainty in machine learning focuses on quantifying and mitigating the uncertainty inherent in model predictions, particularly for structured outputs like images and sequences. Current research emphasizes developing methods to improve the correspondence between predicted uncertainty and actual model errors, often employing Bayesian approaches, energy-based models, or novel loss functions within various architectures including Graph Neural Networks and Variational Autoencoders. This work is crucial for enhancing the reliability and trustworthiness of AI systems across diverse applications, from medical image analysis and autonomous driving to natural language processing and scientific modeling, by providing more accurate assessments of prediction confidence.
