Event Description


As AI technologies and large-scale models continue to integrate into critical applications, prioritizing the robustness and safety of model design has become imperative. Current approaches focus on refining pre-trained models to establish personalized decision rules, enabling reliable predictions and supporting decision-making. The inherent challenges in generalization and safety of these protocols have sparked increased research interest in characterizing model behavior (e.g., diagnosing statistical biases, detecting distribution shifts, predicting generalization capabilities, and evaluating confidence levels), as well as effectively leveraging general-purpose knowledge sources (e.g., pre-trained representations, generative models, and multimodal embeddings) to devise safer solutions. This presentation will delve into innovative strategies for securely and efficiently adapting predictive models, followed by an exploration of methods for proactively detecting failure modes in classification and regression models.
