| Peter Latham: Requiem for the spike - Redwood Center for Theoretical Neuroscience
This is a talk given at the Redwood Center for Theoretical Neuroscience, UC Berkeley on September 5, 2006. Speaker is Peter Latham of Gatsby Computational Neuroscience Unit, University College London. Abstract: A major open question in neuroscience is: "what's the neural code?". The standard approach to answering this, pioneered by Richmond and Optican almost two decades ago [1], is to record spike trains and compute information under different coding models...

This is a talk given at the Redwood Center for Theoretical Neuroscience, UC Berkeley on February 20, 2007. Speaker is Yair Weiss from Hebrew University, Jerusalem. Abstract: Many low-level vision algorithms assume a prior probability over images, and there has been great interest in trying to learn this prior from examples. Since images are very non Gaussian, high dimensional, continuous signals, learning their distribution presents a tremendous computational challenge...

This is a talk given at the Redwood Center for Theoretical Neuroscience, UC Berkeley on March 1, 2007. Speaker is Hiroki Asari, Watson School of Biological Sciences, Cold Spring Harbor Laboratory. Abstract: A striking feature of many sensory processing problems is that there appear to be many more neurons engaged in the internal representations of the signal than in its transduction. For example, humans have about 30,000 cochlear neurons, but at least a thousand times as many neurons in the audi...

This is a talk given at the Redwood Center for Theoretical Neuroscience, UC Berkeley on March 20, 2007. Speaker is Jeff Hawkins of Numenta Inc. Abstract: Jeff Hawkins and Dileep George have proposed a theoretical framework for how the hierarchical structure of neocortex builds a model of the world. This theory, called Hierarchical Temporal Memory (HTM) has been turned into a technology platform and is currently being applied to varied problems of pattern discovery and inference by their company ...

This is last half of a talk given to the Statistics Dept. at UC-Berkeley by Liam Paninski of Columbia Univesrity on Oct 24, 2007. Unfortunately, the first half was not recorded because of technical problems. Sorry! Abstract: There are two basic problems in the statistical analysis of neural data. The ``encoding'' problem concerns how information is encoded in neural spike trains: can we predict the responses of a neuron (or population of neurons), given an arbitrary stimulus or observed motor be...

| Geoff Hinton: How are error derivatives represented in the brain - Redwood Center for Theoretical Neuroscience
This is a talk given by Geoff Hinton, Dept. of Computer Science, University of Toronto, at the Redwood Center for Theoretical Neuroscience on November 27, 2007. Abstract. Neurons need to represent both the presence of a feature in the sensory input and the derivative of an error function with respect to the neural activity. I will describe a simple way in which they can represent both of these very different quantities at the same time and show that this representational scheme would make it eas...

Talk by Todd Horowitz of Harvard Medical School for the Redwood Center for Theoretical Neuroscience, on November 30, 2007 at UC-Berkeley. Abstract: Much of our current understanding of visual attention is built on experimental paradigms that can be characterized as either static or as a series of brief, discontinuous snapshots. However, in our everyday environment, objects around us move smoothly, or we move with respect to the environment...
