Questions about Repair Theory? [2/7, 2009/10/06]

What needs to be clarified from the paper?

THE GAME [3/7, 2009/10/06]

Rules:

• The goal: solve a subtraction problem, using Brown and VanLehn Fig 1
• Teams: the groups for the next project
• Turns: the team describes (in excrutiating detail) the next step in the procedure.
• Scoring: Previous team scores next team. Timed?

Section 3 Discussion [4/7, 2009/10/06]

Five criteria:

1. Empirical adequacy
2. Tailorability (aka "degrees of freedom" or "parameters")
3. Domain independence
4. Elucidates non-studied phenomena (e.g. "bug migration")
5. Learnability

Project 3 [5/7, 2009/10/06]

The assignment

Coming up [6/7, 2009/10/06]

• Thursday: Soar paper by Laird et al. Preview ahead.
• Tuesday: Project 2 due.
• And: Neural networks intro.
• Next Thursday: Midterm quiz
• 5% of overall grade
• Short answer questions
• Goal 1: See how well you understand concepts
• Goal 2: Get you to link together some things we've studied

Soar paper intro [7/7, 2009/10/06]

Another general cognitive architecture like ACT-R. Shared origins. Both use production rules for procedural knowledge. Long(ish), but written for a general audience.

Some key/unfamiliar concepts:

• Behavior = Architecture + Content
• Baseball?
• Problem Spaces
• States
• Operators
• Impasse
• Chunking -- different from ACT-R sense.
