brief description
our world is a noisy world and thus, our premises and conceptions of physical reality remain subject to doubt. how do we perceive and reason in face of such uncertainty? this graduate seminar will provide a careful introduction to probability theory and the various ways it has been applied to model human perceptual and cognitive behavior.
