Weds., Feb. 13, 2002
• New room next time: 24-121
nownext time
MIT holiday schedule
• No classes on Monday, Feb. 18.• Monday’s classes will be held Tuesday.• So next week, we meet
– Tuesday, Feb. 19– Wednesday, Feb. 20
I want to learn names
• Please write your first name in felt or thick pen, so the camera can see it.
• If you really don’t want to be photographed, that’s fine.
“Manifold learning week”
To request a paper…
• To sign-up to do the computer or presentation part of a favorite paper:– Send me an e-mail.
• I’ll also announce to the class when we need people to volunteer.
Other ways to find parts…
• Look for regions that form parts perceptually, e.g., D.D. Hoffman and W. Richards, “Parts of recognition”, Cognition, 18:65-96, 1985.
Other ways to find parts…
Why you don’t want to force the representation to learn how to
translate your data.

Eigenfaces Turk & Pentland (1992) [Note some of the low-frequency
modes are face translation derivatives.—wtf]
