Seminars

Instructions

1. Check the internal calendar for a free seminar slot. If the seminar is not at the booked time of Tueday noon, you have to call or email Sharyn [510-643-4971, climons@berkeley.edu] to book a room. You have to do this as early as possible or she will be pissed. It is not easy for them to find rooms. The 3 rooms they can get are 5101 Tolman, the Beech Room (3rd floor Tolman), and the Barker seminar room (no more than 20 people...). They can also book the LSA large seminar room through MCB if given enough warning.
2. Make a note on this page in the Tentative Speakers section that you are going to invite a speaker. Please include your name and email as host in case somebody wants to contact you.
3. Invite a speaker.
4. As soon as the speaker confirms, put the information in the Confirmed Speakers section.
5. Put the date into the internal calendar
6. Notify kilian [1] that we have a confirmed speaker so that I can update the web page. Please include title and abstract.
7. Notify Sharyn [2] about the seminar date.

• Host: Fritz
• Title: Sparse Representations for the Cocktail Party Problem
• 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 auditory cortex. Such apparently redundant internal representations have sometimes been proposed as necessary to overcome neuronal noise. We instead posit that they directly subserve computations of interest. Here we provide an example of how sparse overcomplete linear representations can directly solve difficult acoustic signal processing problems, using as an example monaural source separation using solely the cues provided by the differential filtering imposed on a source by its path from its origin to the cochlea (the head-related transfer function, or HRTF). In contrast to much previous work, the HRTF is used here to separate auditory streams rather than to localize them in space. The experimentally testable predictions that arise from this model--- including a novel method for estimating a neuron's optimal stimulus using data from a multi-neuron recording experiment---are generic, and apply to a wide range of sensory computations.
