Abstract: 

With the rapid increase in computational power in recent years, deep learning has achieved unparalleled success across various domains. However, deep models are often criticized for their black-box nature, particularly in critical applications where understanding the decision-making process is crucial. The talk will focus on integrating human knowledge through effective regularization of machine learning model behavior to ensure predicted outcomes are both understandable and reliable for humans. Firstly, I will introduce a novel method aimed at enforcing transformation equivalence in model explanations. Secondly, I will present a theoretical framework to improve distributional robustness, which encourages that model predictions rely on invariant features rather than spurious ones. Lastly, I will delve into the analysis of irreversible trajectories in longitudinal data, with applications in Alzheimer's disease studies. These techniques will enhance trust in AI through explainable, fair, and robust models.
