  14. Structure of the Course • Part 1. • Decision-Making in Deterministic Environments • Single-agent: Dynamic programming and search, informed search and heuristics, randomized search, genetic algorithms, constraint satisfaction and path planning • Multi-agent: Adversarial search (mini-max and expecti-mini-max) • Part 2. • Decision-Making in Stochastic Environments • Single-agent: Bayesian networks, Hidden Markov Models, Kalman and Particle filters, Decision and Utility theory, Markov Decision Processes • Multi-agent: Introduction to Game Theory • Part 3. • Learning in Unknown Environments • Supervised learning: Decision trees, Support Vector Machines, Neural Networks • Unsupervised learning: Introduction to Reinforcement Learning

  15. Where are we now?

  16. What are my personal interests? • Agents that must and do appropriately model and reason about the physical properties of their environment: • algorithmic generation of motion (motion planning) • state estimation problems given noisy sensors • and distributed message-passing coordination Robotics Physically-Grounded Agents Computer Games Human Assistants
