- How does PAC learning define when a system can be said to have learned something?
Machine Learning
Algorithms that learn patterns from data.
- How do Bayesian networks let AI systems represent and update uncertain knowledge?
- What is do-calculus, and how does it distinguish correlation from causation?
- Why does the ability to reason about interventions matter for fields like epidemiology and economics?
- How did Angrist and Imbens formalize the mathematics behind natural experiments?
- Why does the study stop short of claiming a causal mechanism between weight and corruption?

- How did Hopfield use the physics of energy landscapes to explain how the brain might store memories?
- How does AlphaFold2 predict a protein's structure directly from its sequence, and how accurate is it compared to experimental methods?
- How did Barto and Sutton's 1998 textbook turn scattered ideas about reward-based learning into a unified discipline?
- What are temporal-difference learning, Q-learning, and policy gradient methods, and why did they become core algorithms of reinforcement learning?
- How do systems like AlphaGo and superhuman game-playing agents trace their lineage back to Barto and Sutton's framework?
- What unifying framework did Barto and Sutton bring to reinforcement learning that had previously been a collection of ad hoc techniques?

- What AI techniques, such as Bayesian Knowledge Tracing and Large Language Models, are driving improvements in adaptability and learning outcomes within tutoring systems?
- Which sensor combination and model architecture performed best under 10-fold cross-validation versus leave-one-subject-out (LOSO) evaluation, and what does that difference imply about generalizing cognitive load classifiers to new individuals?
- Why do CNN-based deep learning models outperform other approaches for binary cognitive load classification on this multimodal dataset?
- How can item-response theory be used to derive difficulty parameters that serve as a proxy for intrinsic cognitive load?
