I am in the process of gathering a list of potential contributors to this session. Anyone interested in contributing a paper to this session should contact me (preferably via e-mail) by the middle of August or so (or ASAP). All I need at this time is the title of the proposed submission, the author's names, and an address (again, preferably an e-mail address). The draft manuscripts will need to be submitted in September. I will provide further details to those who express interest. Note that the term "Artificial Intelligence" as used here is being interpreted in its loosest sense; i.e. topics may include expert systems, neural networks, robotics, genetic algorithms, etc. Thank you for your time.

No matter how complex humans or other species evolve to become, the complexity is neither good nor bad, neither supreme or trivial. It just is. But then rocks and trees just are. It is the aware mind that gives value to the universe BUT that does not mean that the value has any significance in any absolute sense. The fact that we focus on a very small class of behavior and give it great value simply says that is what we do. Nothing more. By the way, the universe is aware and intelligent for we are of the universe.

From: fritz_dg%ncsd.dnet@gte.com Date: Mon, 06 Aug 90 17:27:35 -0400 Are there any non-commercial Neural Network "generator programs" or such that are in Ada? (ie. generates suitable NN code from a set of user designated specifications, code suitable for embedding, etc). I'm interested in - experience developing and using same, lessons learned - to what uses such have been put, successful? - nature of; internal use of lists, arrays; what can be user specified, what can't; built-in limitations; level of HMI attached; compilers used; etc., etc. - and other relevant info developing and applying such from those who have tried developing and using them Am also interested in opinions on: If you were going to design a NN Maker _today_, how would you design it? If Ada were the language, what special things might be done? Motive should be transparent. My sincere thanks to all who respond. If there is interest, I'll turn the info (if any) around to the list in general.

From: KRISH%tifrvax.bitnet@pucc.PRINCETON.EDU Organization: T I F R, Bombay, India Date: Fri, 10 Aug 90 01:48:00 +0700 I am working on neural network based speech recognition with temporal neural networks. The architecture I am using is feed-forward MLP type. I have been using the conventional back-prop algorithm which I realize is computationally expensive. Can anyone tell me how the CONJUGATE GRADIENT based method works for MLP training ? I would appreciate if someone can outline the algorithm for implementation and also give me some references to follow up. (Though our library is not getting many neural net journals/conf. proc.). I would also like to know if there are any LEARNING METHODS for networks with FEED-BACK.

Christopher Dept. of Computer Science Illinois Institute of Technology IIT Center, Chicago, IL 60616 Abstract -------- The massively parallel, communication intensive SIMD algorithm of multilayer back-propagation neural networks was encoded for coarse grained MIMD architectures using a relatively low level message-driven programming paradigm. The computation / communication ratio was software adjusted by defining a "temporal window" grain over the set of training instances. Extensive experiments showed an improvement in multiprocessor utilization over similar reported results and the simulator scaled up well with more complex networks on larger machines. The code can be easily modified to accommodate back-prop variations, like quickprop or cascade-correlation learning, as well as other neural network architectures and learning algorithms.

The simulator will be used by our group of about 10 researchers, directed by Geoffrey Hinton, to explore learning procedures and their applications. It will also be released to some researchers in Canadian Industry. We already have a fast, flexible simulator and the programmer's main job will be to further develop, document, and maintain this simulator. The development may involve some significant re-design of the basic simulator. Additional duties (if time permits) will include: Implementing several different learning procedures within the simulator and investigating their performance on various data-sets; Assisting industrial collaborators and visitors in the use of the simulator; Porting the simulator to faster workstations or to boards that use fast processors such as the Intel i860 or DSP chips; Developing software for a project that uses a data-glove as an input device to an adaptive neural network that drives a speech synthesizer; Assisting in the acquisition and installation of hardware and software required for the project; The applicant should possess a Bachelors or Masters, preferably in Computer Science or Electrical Engineering, and have at least two years programming experience including experience with unix and C, and some experience with graphics. Knowledge of elementary calculus and elementary linear algebra is essential. Knowlege of numerical analysis, information theory, and perceptual or cognitive psychology would be advantageous. Good oral and written communication skills are required. Please send CV + names of two or three references to Carol Plathan, Computer Science Department, University of Toronto, 10 Kings College Road, Toronto Ontario M5S 1A4. You could also send the information by email to carol@ai.toronto.edu or call Carol at 416-978-3695 for more details. The University of Toronto is an equal opportunity employer. ADDITIONAL INFORMATION The job can be given to a non-Canadian if they are better than any Canadians or Canadian Residents who apply. In this case, the non-Canadian would probably start work here on a temporary work permit while the application for a more permanent permit was being processed. There are already SEVERAL good applicants for the job. Candidates who do not already program fluently in C or have not already done neural network simulations stand very little chance. Also, it is basically a programming job. The programmer may get involved in some original research on neural nets, but this is NOT the main part of the job, so it is not suitable for postdoctoral researchers who want to get on with their own research agenda. Interviews will be during September. We will definitely not employ anybody without an interview and we cannot afford to pay travel expenses for interviews (except in very exceptional circumstances). If there are several good applicants from the west coast of the USA, I may arrange to interview them in California. We already have sufficient funding to support the programmer for the next three years. However, we have applied to the Canadian Government for additional funding specifically for this work, and if it comes through (in November 1990) the programmer will be transferred to that source of funding and the simulator will definitely be supplied to Canadian Industry. The job will then require more interactions with industrial users and more systematic documentation, maintainance and debugging of the simulator releases. ------------------------------ Subject: Research associate position available From: austin@minster.york.ac.uk Date: 06 Aug 90 12:36:33 +0000 Please post - University of York Departments of Computer Science, Electronics and Psychology Research Associate post in Neural Networks and Image Classification Applications are invited for a three year research associ- ateship within the departments of Computer Science, Elec- tronics and Psychology on a SERC image interpretation research initiative.

The 80s have even seen a few books published on the subject. These have tended to take drastically different theoretical approaches, and have drawn on varying degrees on fields outside Computer Science and Artificial Intelligence. During this same period, computational and mathematical modelling of language and learning have increasingly been recognized as relevant to assessing the validity of a theory of Language Acquisition or the Nature of Language. Conversely, researchers in Linguistics, Psycholinguistics and Philosophy, as well as Computing, have been considering how and where we can apply our increasing knowledge of the human characteristics and constraints which determine how we solve problems, learn about the world, and use language. The symposium will address all aspects of the relationship between Machine Learning and Natural Language. We not only expect input from researchers in Computer Science and Artificial Intelligence (Machine Learning, Natural Language, Robotics, Vision, Neural Nets, Parallelism, etc.) but wish particularly to encourage relevant contributions from other fields (Linguistics, Psycholinguistics, Philosophy, Neurology, Mathematics, etc.) Specific areas of interest include: Traditional Approaches - Applicability of traditional machine learning. - Applicability of traditional parsing techniques. Complexity Theory - Formal results on learning and language constraints. - Development of effective classifications of language. Cognitive Science - Psychological results on language and restrictions. - Linguistic results on the nature of natural language. Parallel Networks - Neural models of parsing and learning. - Parallel models of parsing and learning. Symbol Grounding - Grounding of Natural Language Systems. - Interaction between Modalities and Learning of Ontology. System Development - Computable hypotheses and heuristics for language learning. - Experimental language learning systems and their rationale. Prospective participants are encouraged to contact a member of the symposium committee to obtain a more detailed description of the symposium goals and issues. Participants should then submit an extended abstract of a paper (500-1000 words) and/or a personal bio-history of work in the area (300-500 words) with a list of (up to 12) relevant publications. We will acknowledge your e-mail enquiries or submissions promptly, and will deal with other forms of communication as quickly as possible. Submissions should be sent by e-mail to powers=sub@informatik.uni-kl.de (and/or reeker@cs.ida.org) by November 16th.
