Listening non-stop for 150min per week, for 16 weeks –4000$ (your tuition).. Catching up on your beauty sleep in the class –300$ (chairs not very comfy) Redoing the in class exam at home –300$ (lost family time) Keeping up with the 17,578,940 billion bytes of /blog –20$ (skimming cost) $ (Brain frying cost) Spending most of your life these last four months hacking lisp or doing home works or writing blog comments for CSE 471 –Priceless… The CSE 471 Commercial ???? What is Stockholm Syndrome and why is it relevant to CSE471?

Announcements Final homework due today; solutions will be posted by tomorrow Participation sheet to be filled and returned today CEAS Evaluations online. –Do take part! Final exam choice –In Class (on Tuesday 5/12 9:50—11:40AM) –Take-home (will be given out before the weekend, and will be due by Tuesday 5/12) –Don’t take.. 

Take-home vs. In-class In-class Get’s done fast—at most 2 hours of pain Get’s graded fast— easy to grade blank sheets Take-home Doesn’t get done fast (You may spend a lot of time doing it) Doesn’t get graded fast—people tend to put up a fight and fill pages 

Announcements Final/Take home will be released by Wed/Thu (check your mail and also homepage) –Will be set like an in-class exam (must be answered on the exam sheet) But you get to do it at home (or milk of kindness overfloweth..) –Wed office hours will be held Review session needed? CEAS Evaluations online. –Do take part! –Comments on TA/Tutor performance can be sent to me using the class anonymous mail facility (or written up in CEAS evals) Today: – Learning completed (Perceptron learning until ~11:30) – Interactive review (11:30—12+) – Summary of what is not done (~5min)

What we did Week 6: KR & Prop logic Week 7: prop logic Week 1: Intro; Intelligent agent design [R&N Ch 1, Ch 2] Week 2: Problem Solving Agents [R&N Ch ] Week 3: Informed search [R&N Ch ] Week 4: CSPs and Local Search[R&N Ch ; Ch 4 4.3] Week 5: Local Search and Propositional Logic[R&N Ch 4 4.3; Ch ] Week 6: Propositional Logic --> Plausible reasoning[R&N Ch ; [ch ]] Week 7: Representations for Reasoning with Uncertainty[ch ]] Week 8: Bayes Nets: Specification & Inference[ch ]] Week 9: Bayes Nets: Inference[ch ]] (Here is a fully worked out example of variable elimination) Week 10: Sampling methods for Bayes net Inference; First-order logic start[ch 13.5; ] Week 11: Unification, Generalized Modus-Ponens, skolemization and resolution refutation. Week 12: Reasoning with change  Planning Week 13: Planning, MDPs & Gametree search Week 14: Learning

Representation Mechanisms: Logic (propositional; first order) Probabilistic logic Learning the models Search Blind, Informed Planning Inference Logical resolution Bayesian inference How the course topics stack up…

Learning Dimensions: What can be learned? --Any of the boxes representing the agent’s knowledge --action description, effect probabilities, causal relations in the world (and the probabilities of causation), utility models (sort of through credit assignment), sensor data interpretation models What feedback is available? --Supervised, unsupervised, “reinforcement” learning --Credit assignment problem What prior knowledge is available? -- “Tabularasa” (agent’s head is a blank slate) or pre-existing knowledge

A Farside treasury… It matters not what you cover, but what you uncover

Rao: I could've taught more...I could've taught more, if I'd just...I could've taught more... Yunsong: Rao, there are thirty people who are mad at you because you taught too much. Look at them. Rao: If I'd made more time...I wasted so much time, you have no idea. If I'd just... Yunsong: There will be generations (of bitter people) because of what you did. Rao: I didn't do enough. Yunsong: You did so much. Rao: This slide. We could’ve removed this slide. Why did I keep the slide? Two minutes, right there. Two minutes, two more minutes.. This music, a bit on reinforcement learning. This review. Two points on bagging and boosting. I could easily have made two for it. At least one. I could’ve gotten one more point across. One more. One more point. A point, Yunsong. For this. I could've gotten one more point across and I didn't.  Adieu with an Oscar Schindler Routine.. Schindler: I could've got more...I could've got more, if I'd just...I could've got more... Stern: Oskar, there are eleven hundred people who are alive because of you. Look at them. Schindler: If I'd made more money...I threw away so much money, you have no idea. If I'd just... Stern: There will be generations because of what you did. Schindler: I didn't do enough. Stern: You did so much. Schindler: This car. Goeth would've bought this car. Why did I keep the car? Ten people, right there. Ten people, ten more people...(He rips the swastika pin from his lapel) This pin, two people. This is gold. Two more people. He would've given me two for it. At least one. He would've given me one. One more. One more person. A person, Stern. For this. I could've gotten one more person and I didn't. Top few things I would have done if I had more time Statistical Learning Reinforcement Learning; Bagging/Boosting Planning under uncertainty and incompleteness Ideas of induced tree-width Multi-agent X (X=search,learning..) PERCEPTION (Speech; Language…) Be less demanding more often (or even once…)
