Plaut Departments of Psychology and Computer Science, Carnegie Mellon University, and the Center for the Neural Basis of Cognition, Pittsburgh PA, USA To appear in Language and Cognitive Processes The traditional view of the lexical system stipulates word-specific representations and separate pathways for regular and exception words. An alternative approach views lexical knowledge as developing from general learning principles applied to mappings among distributed representations of written and spoken words and their meanings. On this distributed account, distinctions among words and between words and nonwords are not reified in the structure of the system but reflect the sensitivity of learning to the relative systematicity in the various mappings. Two simulation experiments address findings that have seemed problematic for the distributed approach. Both involve a consideration of the role of semantics in normal and impaired lexical processing. The first experiment accounts for patients with impaired comprehension but intact reading in terms of individual differences in the division of labor between the semantic and phonological pathways. The second experiment demonstrates that a distributed network can reliably distinguish words from nonwords based on a measure of familiarity defined over semantics. The results underscore the importance of relating function to structure in the lexical system within the context of an explicit computational framework. ftp-host: cnbc.cmu.edu [128.2.244.1] ftp-file: pub/user/plaut/papers/PlautINPRESSLCP.structure.ps.Z OR pub/user/plaut/papers/uncompressed/PlautINPRESSLCP.structure.ps ftp://cnbc.cmu.edu:/pub/user/plaut/papers/PlautINPRESSLCP.structure.ps.Z 19 pages; 183Kb compressed; 498Kb uncompressed =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= David Plaut Center for the Neural Basis of Cognition and Mellon Institute 115, CNBC Departments of Psychology and Computer Science Carnegie Mellon University MI 115I, 412/268-5145 (fax -5060) 4400 Fifth Ave., Pittsburgh PA 15213-2683 http://www.cnbc.cmu.edu/~plaut "Doubt is not a pleasant condition but certainty is an absurd one." -Voltaire =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= From adali@engr.umbc.edu Fri Jan 3 00:32:50 1997 Received: from lucy.cs.wisc.edu (lucy.cs.wisc.edu [128.105.2.11]) by sea.cs.wisc.edu (8.6.12/8.6.12) with ESMTP id AAA22977 for ; Fri, 3 Jan 1997 00:32:46 -0600 Received: from TELNET-1.SRV.CS.CMU.EDU (TELNET-1.SRV.CS.CMU.EDU [128.2.254.108]) by lucy.cs.wisc.edu (8.7.6/8.7.3) with SMTP id AAA16700 for ; Fri, 3 Jan 1997 00:32:44 -0600 (CST) Received: from TELNET-1.SRV.CS.CMU.EDU by telnet-1.srv.cs.CMU.EDU id aa07542; 2 Jan 97 19:42:11 EST Received: from DST.BOLTZ.CS.CMU.EDU by TELNET-1.SRV.CS.CMU.EDU id aa07540; 2 Jan 97 19:33:21 EST Received: from DST.BOLTZ.CS.CMU.EDU by DST.BOLTZ.CS.CMU.EDU id aa10095; 2 Jan 97 19:32:33 EST Received: from RI.CMU.EDU by B.GP.CS.CMU.EDU id aa10997; 2 Jan 97 16:17:10 EST Received: from coe1.engr.umbc.edu by RI.CMU.EDU id aa28673; 2 Jan 97 16:16:10 EST Received: from akdeniz.engr.umbc.edu (adali@akdeniz.engr.umbc.edu [130.85.110.116]) by coe1.engr.umbc.edu (8.7.6/8.6.9) with ESMTP id QAA03132; Thu, 2 Jan 1997 16:16:01 -0500 (EST) From: Tulay Adali Received: (adali@localhost) by akdeniz.engr.umbc.edu (8.8.4/8.6.5) id VAA18802; Thu, 2 Jan 1997 21:16:00 GMT Message-Id: <199701022116.VAA18802@akdeniz.engr.umbc.edu> Subject: CFP: NNSP'97 Special Session -Apps of NNs in Biomedical SP To: Connectionists@cs.cmu.edu Date: Thu, 2 Jan 1997 16:16:00 -0500 (EST) Cc: adali@umbc.edu X-Mailer: ELM [version 2.4 PL23] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit CALL FOR PAPERS ------------------------------------------------ Special Session on Applications of Neural Networks in Biomedical Signal Processing ---------------------------------------------------------------- NNSP'97- IEEE WORKSHOP ON NEURAL NETWORKS FOR SIGNAL PROCESSING ---------------------------------------------------------------- ----------------------------------Session Organizer: Tulay Adali Biomedical signal processing problems, with their particular features, challenges, and definition of objectives, have provided a unique platform for the application of artificial neural networks (ANNs) and the exploration of their relationship to other techniques. In this special session organized within NNSP'97, our aim is to bring researchers in the field together in a forum to present and discuss promising applications of ANNs in the biomedical domain and their relationship to more conventional ones in terms of performance, cost, and implementation. Contributions are sought dealing with both single (EEG, ECG, sensory data, etc.) and multi-dimensional (MR, PET, CT, functional MR, etc.) biomedical signals. Some of the possible areas of application are; * pattern recognition and feature extraction for computer aided diagnosis and prognosis * signal analysis (quantification, segmentation, etc.) * signal enhancement/restoration * data compression * reconstruction * data fusion/registration * biological system modeling NNSP'97 is the seventh of a series of IEEE Workshops on Neural Networks for Signal Processing and this year will be held in the Amelia Island Plantation, Florida, 24-26 September 1997. Camera-ready full papers of accepted proposals will be published in a hard-bound volume by IEEE and distributed at the workshop.

The aims of this workshop are: to foster interdisciplinary discussion and debate on key issues relating to biological and artificial behaviour generating mechanisms; to highlight the value and potential of collaborations at the new interface between biology, computer science and engineering; to consider the philosophical issues arising from the notion of "autonomy", especially in artificial systems; to consider emerging industrial and commercial applications for which this interface is likely to be an essential enabling factor; to discuss how a UK community interested in these issues may be established and whether new mechanisms and initiatives from funding bodies may be appropriate; to consider how this field in the UK can be promoted to ensure that we remain in the forefront worldwide. The workshop is divided into three sections (Setting the Stage; Vision, Behaviour and Robots; Complexity). Each session will be divided into two parts: a series of ten minute presentations in which speakers raise key issues and pose open questions, followed by a panel discussion. Contributions from members of the audience will also be encouraged. ------------------------------------------------------------------------------ One-Day Workshop 24 January 1997 University of Sussex, Brighton, UK Autonomous Behaviour in Animals and Robots: Perspectives from Neuroscience, Engineering and Philosophy P R O G R A M M E 10.00-10.30 Reception; Coffee 10.30-10.45 Welcome and Introduction Phil Husbands and Michael O'Shea SESSION A SETTING THE STAGE CHAIR: MICHAEL O'SHEA 10.45-10.55 Understanding the Nervous System Danny Osorio 10.55-11.05 Artificial Autonomous Agents Dave Cliff 11.05-11.15 Philosophical Perspectives Mike Wheeler 11.15-12.30 Discussion of Issues Arising Chair: Maggie Boden with Panel of Discussants (David McFarland; Brendan McGonnigle; Geoffrey Miller; Steven Rose; Aaron Sloman) 12.30-2.00 Lunch SESSION B VISION, BEHAVIOUR AND ROBOTS CHAIR: PHIL HUSBANDS 2.00-2.10 What is Natural Vision For?

Because of global connectivity, WTA networks, however, do not encode spatial relations in the input, and thus cannot support sensory and perceptual processing where spatial relations are important. We propose a new architecture that maintains spatial relations between input features. This selection network builds on LEGION (Locally Excitatory Globally Inhibitory Oscillator Networks) dynamics and slow inhibition. In an input scene with many objects (patterns), the network selects the largest object. This system can be easily adjusted to select several largest objects, which then alternate in time. We further show that a two-stage selection network gains efficiency by combining selection with parallel removal of noisy regions. The network is applied to select the most salient object in real images. As a special case, the selection network without local excitation gives rise to a new form of oscillatory WTA.
