<eventitem date="2010-10-12" time="04:30 PM" room="MC4061" title="How to build a brain: From single neurons to cognition">
<short><p>Theoretical neuroscience is a new discipline focused on constructing mathematical models of brain function. It has made significant headway in understanding aspects of the neural code. However, past work has largely focused on small numbers of neurons, and so the underlying representations are often simple. In this talk I demonstrate how the ideas underlying these simple forms of representation can underwrite a representational hierarchy that scales to support sophisticated, structure-sensitive representations.

<abstract><p>Theoretical neuroscience is a new discipline focused on constructing
mathematical models of brain function. It has made significant
headway in understanding aspects of the neural code. However,
past work has largely focused on small numbers of neurons, and
so the underlying representations are often simple. In this
talk I demonstrate how the ideas underlying these simple forms of
representation can underwrite a representational hierarchy that
scales to support sophisticated, structure-sensitive
representations. I will present a general architecture, the semantic
pointer architecture (SPA), which is built on this hierarchy
and allows the manipulation, processing, and learning of structured
representations in neurally realistic models. I demonstrate the
architecture on Progressive Raven's Matrices (RPM), a test of
general fluid intelligence.

<short><p><i>By Peter Barfuss</i>. In this talk, I will go over the concepts used in video encoding (such as motion estimation/compensation, inter- and intra- frame prediction, quantization and entropy encoding), and then demonstrate these concepts and algorithms in use in the MPEG-2 and the H.264 video codecs. In addition, some clever optimization tricks using SIMD/vectorization will be covered, assuming sufficient time to cover these topics.

<short><p>Come meet and greet your professors, advisors, and the heads of the school. Talk to the CSC executive and other upper year students about CS at Waterloo. Free food and beverages will also be available, so there is really no excuse to miss this.
