The first Robotics Exhibition and Competition sponsored by the Association for the Advancement of Artificial Intelligence was held in San Jose, California, on 14-16 July 1992 in conjunction with the Tenth National Conference on AI. This article describes the history behind the competition, the preparations leading to the competition, the threedays during which 12 teams competed in the three events making up the competition, and the prospects for other such competitions in the future.

The system has reduced time The system, developed by Stereo-spent by store personnel on the telephone seeking answers to point-of-sale Graphics (San Rafael, Calif.), uses a technical problems, and it allows the help desk analysts to handle a wider range video projector equipped with a of responsibilities for the company. Viewers wear passive eye Swedish stock exchange, has developed an intelligent system to advise on how wear which allows each eye to view to deal in stocks and shares. The company's "hit rate" of dealing correctly with the appropriate image, thereby providing stocks has reportedly increased from 60% to 90%. IntelliCorp Inc. (Mountain View, Calif.), an expert system vendor, and James Inference Corp. (El Segundo, Calif.), Martin & Co. (Reston, Va.), a computer-aided software engineering (CASE) consulting a supplier of expert system development group, have launched a field test program for an object-oriented information tools, has teamed up with IDS engineering environment. The new product, called Object Management Financial Services (Minneapolis, Workbench, directly supports rapid application development, and will either Minn.) to jointly develop Macintosh generate a system immediately or draw information from currently available versions of Inference products.

Because of the complexity of the application and the large amount of data, the problem cannot be solved by using a single method. The solution we propose is to build multimodules NN architectures where several NN cooperate together. Such system suffer from generic problem for whom we propose solutions. They allow to reach accurate performances for multi-valued function approximations and probability estimations. The results are compared with six other methods which have been used for this problem. We show that the methodology we have developed is general and can be used for a large variety of applications.

There exist large classes of time series, such as those with nonlinear moving average components, that are not well modeled by feedforward networks or linear models, but can be modeled by recurrent networks. We show that recurrent neural networks are a type of nonlinear autoregressive-moving average (N ARMA) model. Practical ability will be shown in the results of a competition sponsored by the Puget Sound Power and Light Company, where the recurrent networks gave the best performance on electric load forecasting. 1 Introduction This paper will concentrate on identifying types of time series for which a recurrent network provides a significantly better model, and corresponding prediction, than a feedforward network. Our main interest is in discrete time series that are parsimoniously modeled by a simple recurrent network, but for which, a feedforward neural network is highly non-parsimonious by virtue of requiring an infinite amount of past observations as input to achieve the same accuracy in prediction. Our approach is to consider predictive neural networks as stochastic models.

Two projection based feedforward network learning methods for modelfree regression problems are studied and compared in this paper: one is the popular back-propagation learning (BPL); the other is the projection pursuit learning (PPL).
