Marr's level : Imagine some told us about a computer system which has a program running on
it and ready to serve users. There are three questions that will come to our mind.
1. What does this program do? What service does it provide? (say t

Structure Mapping in Analogy and Similarity by Dedre Gentner and Markman
Similarity and analogy involve a process of structural alignment and mapping. Similarity is
Structure Mapping for Analogy

Have people tested how being bilingual (ex: Mandarin-English) affects Mandarin speech?
Is it really possible to be bilingual with no accent for either of their languages?
Why are there differences between Spanish-English bili
Second half of course:
How are position, orientation, and bar width coded?
Can a simple cell tuned to 45 degree orientation tell you that you are seeing a 45 degree tilted
Could get weak response if tilted wrong way, wrong width, or could
Solving Geometric Analogy Problems Through Two-Stage Analogical Mapping by Forbus,
Tomai, Lovett, Usher
The structure mapping model of analogy, when combined with high-level visual processing
and qualitative representations, can solve the same kinds of g

Compare Sandy with Irene example.
Analogical reasoning in action
To argue for a conclusion, find some similar event
To argue for the conclusion, focus on aspects that heighten similarity- the more similar
the event, the more likely
Qualitative Models Readings
Qualitative modeling concerns the representations and reasoning that people use to
understand continuous aspects of the world.
Understanding the representations and processes that underlie such reasoning is a goal of
4 step analogical processing in detail:
Modeling Shape comparison
o In Step 1, each glyphs ink is decomposed into a set of edges. These edges represent
the atomic parts of our shape representations.
Edges identified via 5 step algorithm
