AISTATS*2012 Poster Sessions

There are three poster sessions: Poster Session I, Poster Session II, and Poster Session III. Each poster has a poster number. Note that posters with nearby numbers should be located to each other in the conference hall, and that the poster board is two meters high one meter wide.

Poster Session I (Saturday 21 April)

Subjects roughly include Structured outputs, multitask, deep learning, bandits, clustering, decision processes, text, active learning, computational biology, low rank models and matrix completion, and speech.

Posters with nearby numbers should be located to each other in the conference hall. Note that the poster board is two meters high one meter wide.
