We embed this model in moderate noise, typical of the context presented in real neocortex, using PATHINT, a non- Monte-Carlo path-integral algorithm that is particularly adept in handling nonlinear Fokker-Planck systems. This approach shows promise to investigate whether chaos in neocortex, as predicted by such models, can survive in noisy contexts.

Abstract: This thesis addresses the non-linear system identification problem, and in particular, investigates the use of neural networks in system identification. An overview of different possible model structures is given in a common framework. A nonlinear structure is described as the concatenation of a map from the observed data to the regressor, and a map from the regressor to the output space. This divides the model structure selection problem into two problems with lower complexity: that of choosing the regressor and that of choosing the non-linear map. The possible choices for the regressors consists of past inputs and outputs, and filtered versions of them. The dynamics of the model depends on the choice of regressor, and families of different model structures are suggested based on analogies to linear black-box models. State-space models are also described within this common framework by a special choice of regressor. It is shown that state-space models which have no parameters in the state update function can be viewed as an input-output model preceded by a pre-filter. A parameterized state update function, on the other hand, can be seen as a data driven regressor selector. The second step of the non-linear identification is the mapping from the regressor to the output space. It is often advantageous to try some intermediate mappings between the linear and the general non-linear mapping. Such non-linear black-box mappings are discussed and motivated by considering different noise assumptions. The validation of a linear model should contain a test for non-linearities and it is shown that, in general, it is easy to detect non-linearities. This implies that it is not worth spending too much energy searching for optimal non-linear validation methods for a specific problem. Instead the validation method should be chosen so that it is easy to apply. Two such methods, based on polynomials and neural nets, are suggested. Further, two validation methods, the correlation-test and the parametric F-test, are investigated. It is shown that under certain conditions these methods coincide. Parameter estimates are usually based on criterion minimization. In connection with neural nets it has been noted that it is not always optimal to try to find the absolute minimum point of the criterion. Instead a better estimate can be obtained if the numerical search for the minimum is prematurely stopped. A formal connection between this stopped search and regularization is given. It is shown that the numerical minimization of the criterion can be view as a regularization term which is gradually turned to zero. This closely connects to, and explains, what is called overtraining in the neural net literature.

We find that the storage capacity $\alpha_c$ can be less than 2 if similar patterns are mapped onto different outputs and vice versa. As long as the patterns are in general position we obtain, in contrast to previous works, that $\alpha_c \geq 1$ in agreement with Cover's theorem. Numerical simulations confirm the results. ------------------------------------------------------------------ From martin.davies@psy.ox.ac.uk Tue May 23 02:36:57 1995 Received: from lucy.cs.wisc.edu by sea.cs.wisc.edu; Tue, 23 May 95 02:36:51 -0500; AA26336 Received: from TELNET-1.SRV.CS.CMU.EDU by lucy.cs.wisc.edu; Tue, 23 May 95 02:36:48 -0500 Received: from TELNET-1.SRV.CS.CMU.EDU by telnet-1.srv.cs.CMU.EDU id ab20058; 22 May 95 20:12:54 EDT Received: from DST.BOLTZ.CS.CMU.EDU by TELNET-1.SRV.CS.CMU.EDU id aa20041; 22 May 95 19:47:41 EDT Received: from DST.BOLTZ.CS.CMU.EDU by DST.BOLTZ.CS.CMU.EDU id aa13226; 22 May 95 19:47:28 EDT Received: from CS.CMU.EDU by B.GP.CS.CMU.EDU id aa26026; 22 May 95 13:20:27 EDT Received: from oxmail2.ox.ac.uk by CS.CMU.EDU id aa11035; 22 May 95 13:18:57 EDT Received: from ep1.psych.ox.ac.uk by oxmail2.ox.ac.uk. with SMTP (PP) id <08612-0@oxmail2.ox.ac.uk.>; Mon, 22 May 1995 18:15:28 +0100 Received: from Mac8 by ep1.psych.ox.ac.uk (8.6.8/8.6.6) with SMTP id SAA02242 for ; Mon, 22 May 1995 18:15:53 +0100 X-Mailer: InterCon TCP/Connect II 1.2.1 Message-Id: <9505221815.AA31230@Mac8> Date: Mon, 22 May 1995 18:15:31 +0100 From: Martin Davies To: connectionists@cs.cmu.edu Subject: Euro-SPP '95 ************************************************************ EUROPEAN SOCIETY FOR PHILOSOPHY AND PSYCHOLOGY FOURTH ANNUAL CONFERENCE St. Catherine's College Oxford OX1 3UJ 30 August - 1 September 1995 ************************************************************ This conference is supported by the McDonnell-Pew Centre for Cognitive Neuroscience and by the Mind Association. ************************************************************ The Fourth Annual Conference of the European Society for Philosophy and Psychology will be held at St. Catherine's College Oxford, from Wednesday 30 August to Friday 1 September 1995.

These positions have a nominal start date of 1 October 1995, although earlier or later start dates can be agreed if appropriate. Validation and Verification of Neural Network Systems ----------------------------------------------------- (Two Posts) One of the major factors limiting the widespread exploitation of neural networks has been the perceived difficulty of ensuring that a trained network will continue to perform satisfactorily when installed in an operational system. In the case of safety-critical systems it is clearly vital that a high degree of overall system integrity be achieved. However, almost all potential applications of neural networks entail some level of undesirable consequence if the network generates incorrect or inaccurate predictions. Currently there is no general framework for assessing the robustness of neural network solutions or of systems containing embedded neural networks. This substantial and ambitious programme will address the basic issues involved in neural network validation and verification in the context both of stand-alone network solutions and of embedded systems. It will develop and demonstrate robust techniques for quantifying the reliability of neural network predictions, and will also provide the necessary theoretical foundation of a subsequent framework for neural network system validation. This project will address the theoretical basis for determining valid generalisation and error estimates for neural network predictions, and will aim to understand the impact of uncertainties in network predictions on overall system performance in the context of embedded applications. It will also demonstrate the use of these techniques for validation of network solutions through case studies based on real-world applications and data, which will be provided by industrial collaborators. Potential candidates should be mathematically and computationally competent with a background either in artificial neural networks or a relevant field. These posts are tenable for two years in the first instance, with a possible extension for a further three years. Nonstationary Feature Extraction and Tracking for the Classification -------------------------------------------------------------------- of Turning Points in Multivariate Time Series ---------------------------------------------- (One Post) The project is aimed at extracting information from nonstationary, nonlinear time series. Real-world examples which have motivated the proposal include: the early classification of highs, lows and sideways drift in financial global bond markets; the forecasting of characteristic clustering such as peaks and troughs in consumer driven electricity load demand, along with the corresponding impacts on pool-price prediction, or the expectation of dynamic loading patterns in telecommunications networks. The key lies in an appropriate {\em representation} of the data. The intended methodology is to extend the theoretical basis of the current state of the art on neural network feature extraction techniques to tackle real-world problems presented by industry and commerce. The emphasis is to seek appropriate representations of nonstationary data such that the resulting `clusterings' may be exploited to perform classification. Because real data is generally nonstationary the principal axes of the feature space change in time and so we need to track this nonstationarity if `market' characteristics as determined by the features are to be useful. Potential candidates should be mathematically and computationally competent with a background either in artificial neural networks, dynamical systems theory, statistical pattern processing, or have relevant experience from a physics or electrical engineering background. This post is tenable for three years. Neural Networks for Visualization of High Dimensional Data ---------------------------------------------------------- (One Post) Visualization has proven to be one of the most powerful ways to interpret and understand complex sets of data, such as records of financial transactions, corporate databases, customer profiles, and marketing surveys. Particular problems arise, however, when the data involves large numbers of variables, corresponding to spaces of high dimensionality. Additionally, the data is often plagued with deficiencies such as missing variables, mislabelled values, and inconsistencies in the representations of different quantities (for instance, the same attribute may be represented in different ways in different parts of the data base). Such problems severely limit the performance of current visualization algorithms. This project will investigate the theoretical basis for visualizing data using neural networks, and will develop practical techniques for visualization applicable to large-scale data sets. These techniques will be based, for example, on recent developments in latent-variable density estimation. Potential candidates should be mathematically and computationally competent with a background either in artificial neural networks or a relevant field. This post is tenable for two years. Neural Computing Research Group ------------------------------- The Neural Computing Research Group currently comprises the following academic staff Chris Bishop Professor David Lowe Professor David Bounds Professor Geoffrey Hinton Visiting Professor Richard Rohwer Lecturer Alan Harget Lecturer Ian Nabney Lecturer David Saad Lecturer (arrives 1 August) two further posts (currently being appointed) together with the following Research Fellows Chris Williams Shane Murnion Alan McLachlan Huaihu Zhu a full-time software support assistant, and eleven postgraduate research students.

The ftp archive has been moved from thalamus.wustl.edu (which has been down for a while now), and more convenient access on the World Wide Web is now in place. (1) The archive of PNP technical reports is now available by anonymous ftp to wuarchive.wustl.edu, in the directory doc/techreports/wustl.edu/philosophy. Files have the form author.title.format, where format is usually ASCII or PS. An "INDEX" file contains an index with abstracts. Plenty of new papers here! (2) There is now a PNP home page on the WWW, at http://www.artsci.wustl.edu/~philos/pnp.html. At the moment this serves mostly as a gateway to the PNP archive, but more will be appearing shortly. Those with WWW access will probably want to use this to get to the archive, rather than the ftp option. (3) My own home page is now set up at http://www.artsci.wustl.edu/~chalmers/. This has links to a number of my papers on consciousness, content, artificial intelligence, and other topics (including some papers that aren't in the PNP archive), and also to my annotated bibliography in the philosophy of mind (see below). (4) There is now a convenient home page for my bibliography in the philosophy of mind at http://www.artsci.wustl.edu/~chalmers/biblio.html. Many of the current links to the bibliography on the net proceed via an extraordinarily slow connection through apa.oxy.edu and Indiana; this should work much better. Incidentally the bibliography is also available by anonymous ftp to wuarchive in the directory mentioned above, files chalmers.biblio.*. The current version has about 1830 entries in 5 parts. Those who maintain pages with links to these things (especially the archive and the bibliography) might like to update them. --Dave Chalmers (dave@twinearth.wustl.edu) From Guszti.Bartfai@Comp.VUW.AC.NZ Wed May 24 00:24:40 1995 Received: from lucy.cs.wisc.edu by sea.cs.wisc.edu; Wed, 24 May 95 00:24:37 -0500; AA19842 Received: from TELNET-1.SRV.CS.CMU.EDU by lucy.cs.wisc.edu; Wed, 24 May 95 00:24:35 -0500 Received: from TELNET-1.SRV.CS.CMU.EDU by telnet-1.srv.cs.CMU.EDU id aa21491; 23 May 95 19:13:38 EDT Received: from DST.BOLTZ.CS.CMU.EDU by TELNET-1.SRV.CS.CMU.EDU id aa21489; 23 May 95 19:03:45 EDT Received: from DST.BOLTZ.CS.CMU.EDU by DST.BOLTZ.CS.CMU.EDU id aa14089; 23 May 95 19:03:39 EDT Received: from EDRC.CMU.EDU by B.GP.CS.CMU.EDU id aa16308; 23 May 95 18:47:15 EDT Received: from kaukau.comp.vuw.ac.nz by EDRC.CMU.EDU id aa05001; 23 May 95 18:46:36 EDT Received: from circa.comp.vuw.ac.nz (circa.comp.vuw.ac.nz [130.195.5.12]) by kaukau.comp.vuw.ac.nz (8.6.B/8.6.9-VUW) with ESMTP id KAA13154 for ; Wed, 24 May 1995 10:45:44 +1200 From: Guszti Bartfai Received: from localhost (guszti@localhost) by circa.comp.vuw.ac.nz (8.6.10/8.6.9-VUW) with SMTP id KAA19738 for ; Wed, 24 May 1995 10:46:00 +1200 Message-Id: <199505232246.KAA19738@circa.comp.vuw.ac.nz> To: Connectionists@cs.cmu.edu Subject: Paper announcement Date: Wed, 24 May 1995 10:45:59 +1200 The following paper has been accepted for publication in the journal "Neural Networks". Title: On the Match Tracking Anomaly of the ARTMAP Neural Network Author: Guszti Bartfai Department of Computer Science Victoria University of Wellington New Zealand Abstract: This article analyses the {\em match tracking anomaly} ({\em MTA}) of the ARTMAP neural network. The anomaly arises when an input pattern exactly matches its category prototype that the network has previously learned, and the network generates a prediction (through a previously learned associative link) that contradicts the output category that was selected upon presentation of the corresponding target output. Carpenter at al.\ claimed that such anomalous situation will never arise if the (binary) input vectors have the same number of 1's [Carpenter91]. This paper shows that such situations {\em can} in fact occur. The {\em timing} according to which inputs are presented to the network in each learning trial is crucial: if the target output is presented to the network {\em before} the corresponding input pattern, certain pattern sequences will lead the network to the {\em MTA}. Two kinds of {\em MTA} are distinguished: one that is independent of the choice parameter ($\beta$) of the ART$_b$ module, and another that is not. Results of experiments that were carried out on a machine learning database demonstrate the existence of the match tracking anomaly as well as support the analytical results presented here.

Factorial hidden Markov models Zoubin Ghahramani and Michael I. Jordan Department of Brain & Cognitive Sciences Massachusetts Institute of Technology Cambridge, MA 02139 We present a framework for learning in hidden Markov models with distributed state representations. Within this framework, we derive a learning algorithm based on the Expectation--Maximization (EM) procedure for maximum likelihood estimation. Analogous to the standard Baum-Welch update rules, the M-step of our algorithm is exact and can be solved via a set of linear equations. However, due to the combinatorial nature of the hidden state representation, the exact E-step is intractable. A simple and tractable mean field approximation is derived. Promising empirical results on a small time series modeling problem are presented for both the mean field approximation and Gibbs sampling.

ISAP comprises the Department of Psychology and the Tizard Centre. The Department has 16 HEFCE funded teaching staff in addition to associated research and support staff, independently funded research staff and postgraduate students. The Tizard Centre has a similar number of staff but is funded primarily from research and consultancy contracts. Further Psychology posts have been approved by the University. As part of the Department s development plan we are seeking applications for a permanent lectureship from active post-doctoral researchers in the general area of cognitive neuroscience. Candidates with research interests in any area of cognitive neuroscience or its related disciplines are encouraged to apply. Of particular interest will be candidates who have an expertise in computational, especially connectionist, modelling. Ideally, the successful applicant will be expected to take up his/her appointment by the 1st September 1995 or as soon as possible thereafter. Main responsibilities of the post holder The successful candidate will have both research and teaching responsibilities. General information Research The Departments research activities are concentrated in the broad areas of cognition and of social psychology. Current research within the cognitive neuroscience group includes investigations of object processing, categorization, speech production and language disorders. In all these areas, staff are involved in experimental research with normal subjects as well as the testing of brain-damaged subjects and attempts to model findings using connectionist systems. Research programmes in Social Psychology include the areas of group processes, psychology of health and social psychological aspects of Forensic Psychology. In all of these fields, the department has an excellent record of attracting research funds and studentships. At present substantial research awards are held from the ESRC, ARC (Australian Research Council), the Rowntree Foundation, Nuffield, Canterbury and Thanet Healthcare Trust, Wellcome and The Leverhulme Trust. The successful candidate will be expected and encouraged to develop a substantive programme of research based on his/her own interests. It should also be noted that existing members of staff are keen to develop collaborative research projects where common interests exist.

Teaching The Department currently offers undergraduate BSc degrees in Psychology, Social Psychology, Social and Clinical Psychology (including Applied, four-year variants), along with an MSc in Social and Applied Psychology. In addition two new MSc degrees, in Forensic Psychology and Health Psychology will be available from October 1995, and an MSc in Cognitive Neuroscience is planned in cooperation with the Department of Biology. The Department has ESRC priority recognition (Mode A and B) for its postgraduate training. We have a large and lively group of postgraduate students, and with our current and planned MSc programmes and our involvement in European Exchange Programmes we are planning for a significant long-term expansion in our postgraduate training and research. The post holder s main teaching responsibility will be in the second and third years of our undergraduate programmes. At present, second year students have the option of taking a course which includes perception, language, memory and basic issues relating to neural computation. Third year students have an option to study Neuropsychology (convened by Dr Donnelly). This course is split into two units. In unit 1 we address basic methodological issues and the neuropsychology of vision and in unit 2 we address the neuropsychology of language, memory and other higher order processes. The appointee would be expected to contribute (along with Drs Donnelly, Weekes and Lloyd-Jones) to both units and the final component of the 2nd year course, and to develop teaching in their own area of research. The appointee will also be expected to take over the modest administrative role involved in convening the second year course. In addition, all final year undergraduate students currently undertake an empirical project and the person appointed will take a share of the supervision and support of these, as well as postgraduate supervision. Teaching methods at Kent comprise the usual mix of large lecture format (especially at the first and second-year undergraduate level), small group seminar teaching, and co-operative group working. Administration The Institute has a fully devolved budget for all non-staff costs and the management of this falls to the relevant Head of Department. All staff contribute to the administration of the Department, and several key managerial responsibilities are delegated from the Head of Department to other colleagues. The staff responsibilities change from year to year in the light of varying teaching and research activities and to allow for study leave. Within this collegial atmosphere a supportive appraisal and probation system is operated under the supervision of senior members of staff. All staff are defined as "research active" and it is the Departmental policy to maximise time available for research. The administration of the Department's teaching and research activities is supported by a full-time departmental administrator and secretarial staff. Technical facilities The Department has a good level of technical support and provision. We have installed a new computer network comprising both Apple Macintoshs and PC's. All staff have their own microcomputers in their offices. We are connected to the University's central computing facilities which include several UNIX-based super-minicomputers and access to national and international computer networks. We have recently refurbished our laboratory facilities to include a high quality audio-visual studio.

Glassman Siemens Corporate Research 755 College Road East Princeton, NJ 08540 Abstract Results are reported from the application of tools for synthesizing, optimizing and analyzing neural networks to an ECG Patient Monitoring task. A neural network was synthesized from a rule-based classifier and optimized over a set of normal and abnormal heartbeats. The classification error rate on a separate and larger test set was reduced by a factor of 2. Sensitivity analysis of the synthesized and optimized networks revealed informative differences. Analysis of the weights and unit activations of the optimized network enabled a reduction in size of the network by a factor of 40% without loss of accuracy. +=+=+= The paper will appear in the Proceedings of the Workshop on Environmental and Energy Applications of Neural Networks, March 30-31, 1995, Richland, Washington, and is reprinted from the Proceedings of the Third International Congress on Air- and Structure-Borne Sound and Vibration, June 13-15, 1994, Montreal, Quebec, pp. 997-1004, and the Proceedings of the 1993 Symposium on Nonlinear Theory and its Applications, December 5-10, Honolulu, Hawaii, pp. 565-570.

Sutton submitted to NIPS'95 On large problems, reinforcement learning systems must use parameterized function approximators such as neural networks in order to generalize between similar situations and actions. In these cases there are no strong theoretical results on the accuracy of convergence, and computational results have been mixed. In particular, Boyan and Moore reported at last year's meeting a series of negative results in attempting to apply dynamic programming together with function approximation to simple control problems with continuous state spaces. In this paper, we present positive results for all the control tasks they attempted, and for one that is significantly larger. The most important differences are that we used sparse-coarse-coded function approximators (CMACs) whereas they used mostly global function approximators, and that we learned online whereas they learned offline. Boyan and Moore and others have suggested that the problems they encountered could be solved by using actual outcomes ("rollouts"), as in classical Monte Carlo methods, and as in the TD(lambda) algorithm when lambda=1. However, in our experiments this always resulted in substantially poorer performance. We conclude that reinforcement learning can work robustly in conjunction with function approximators, and that there is little justification at present for avoiding the case of general lambda. ________________ The paper is available by ftp as ftp://ftp.cs.umass.edu/pub/anw/pub/sutton/sutton-inprer.ps.gz or via a new WWW interface to my small archive at http://envy.cs.umass.edu/People/sutton/archive.html.

This is a staff position with a focus on speech recognition system design. The job will involve both research and development. Applicants should have several years of experience in designing and writing speech recognition software, and have an interest in developing recognizers that incorporate results from basic research within the group. It would be best if the applicant also had experience in speech research as well, although development experience is the more important qualification. Ordinarily, applicants will have a Ph.D., although strong professional experience can substitute for this requirement. The Realization group at ICSI does a combination of hardware, software, and algorithms for research and development of systems for speech processing and other machine implementations of human signal processing and pattern recognition. In the past, much of the emphasis has been on hybrid neural network/ hidden Markov model based speech recognition, robust recognition in the context of additive and convolutional noise, study of robust properties of the human auditory system, and research into the interaction of statistical sequence recognition with robust signal processing. Hardware and software tools also continue to be developed in the group, leading to strong capabilities for training with computationally intensive algorithms. The group includes a strong group of Berkeley CS and EE graduate students, as well as by fruitful collaborations with other researchers (including Greenberg from Berkeley, Bourlard from Belgium, Hermansky from OGI, Cohen and Franco from SRI, and Robinson from Cambridge U). The group is led by Nelson Morgan. ICSI is an independent, non-profit basic research institute affiliated with the University of California campus in Berkeley, California, and is an Equal Opportunity Employer.
