AI Revision

I have done about 7 hours in 2 days, and that is pretty much it. I did the 2004 paper in 55 minutes and the 2003 paper in 75 (out of 3 hours).
I think I did pretty well in both, but I am now worried that this is false confidence and the questions that appear tomorrow will be such that I can't answer them – I know nothing about planning and am a bit shaky in some other areas.

Here's hoping for 2003 again!

    i hates you.

    I'm still learning the module for the first time. The problem isn't with any conceptual difficulty but remembering lots of facts, algorithms and proofs.

    Yeh. Welcome to what I excel at. Don't worry, I'll get screwed over on Tuesday – 2.5 days to learn Magnetic Properties of Solids Oleg and NMR from scratch.

    See Dan's entry. I've already contributed a bit :-P

    do you know of various examples for different things? specificially all the questions when it asks you to list attributes and whatnot and illustrate with examples.

  6. Simon Brent

    erm. I might do. If I knew exactly what you meant.

    well all those nice easy questions where it asks you to list properties and then give examples. environment properties, fundamental agent types etc.

  8. Simon Brent

    are right. Agent properties = PEAS.
    Environment properties:
    Deterministic/Stochastic/Strategic
    Episodic/Sequential
    Static/Dynamic
    Fully/Partially Observable
    Discrete/Continuous.

    Not so great on examples but I'll try one: environment properties for chess:
    Strategic, Sequential, Static, Fully Observable, Discrete.

    Agent types:
    Simple relfex agent
    Reflex with state
    Goal based
    Utility based.
    I can draw the diagrams and stuff…

  10. Andrew Ingram

    with agent types can you say some examples? I can do the explanations and diagrams but i'm rubbish at thinking up examples in exams.

  11. Simon Brent

    Ok, well to continue the theme I'd say that a chess-playing agent (or anything involved in adversarial search for that matter) would be utility based. Know the goal is useless if something is trying to stop you getting there and you don't know what move is most beneficial.

    Goal based…hmm…how about the robot thingy we did in CS118? Before we programmed it to avoid repetitions it was simply goal based wasn't it – knew nothing but what it was trying to get to.

    The others I can't really think of right now. I'll let you know if I come up with something

    In just over 12 hours I have to sit a paper consisting of twelve 'questions'. 'Questions' = words. Single, evil words. Eg: "Transcendental". "Normativity". "Qualia". "Sublime". I shall be choosing one word and writing a 'philosophical essay' on it (once I have spent half an hour making up a definition for it and trying to figure out at what point I was supposed to have studied it) for three long hours.

    WIN!

    sounds fun. i'm serious here. such restrictions allow some amazing creativity.

    Ouch

  15. Sarah Cooper

    Perhaps, if 'philosophical essay' didn't mean "you should know the correct terminology / history of the topic" blah blah blah… Also it's hard to be creative with words like "qualia", when one can only vaguely remember which branch of philosophy it's supposed to be a relevant part of!

    *Sigh. All will be well. I can be philosophical and stuff… right?

    So the AI exam finishes at 5pm, and here I am back in my room. Time taken: 1 hour 25 minutes Expected mark: 74% (It's not ok to hate me) Edit: Turns out I missed 1e). Dammit that was an easy mark thrown away :-(
