In this paper, the authors propose a two-dimensional map, where the processing elements correspond to specific instances of leaky integrators whose parameters (or tops) are learned in a self-organizing manner: in this way the map becomes a topologic representation of temporal sequences whose presence in a continuous temporal data flow is detectable by means of the activation level of the corresponding neurons.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126358927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To minimize the effect of weather on the forecast of the commercial load, it is further decomposed into four autonomous sections of six hour durations. The optimal input for a training set is determined based on the sum of the squared residuals of the predicted loads. The input patterns are made up of the immediate past four or five hours load and the output is the fifth or the sixth hour load. The results obtained using the proposed approach provide evidence that in the absence of some influential variables such as temperature, a careful selection of training patterns will enhance the performance of the artificial neural network in predicting the power system load.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126443993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article describes sparse adaptive memory (SARI), an associative memory built upon the strengths of Parzen classifiers, nearest neighbor classifiers, feedforward neural networks, and is related to learning vector quantization. A key feature of this learning architecture is the ability to adaptively change its prototype patterns in addition to its output mapping. As SAM changes the prototype patterns in the list, it isolates modes in the density functions to produce a classifier that is in some senses optimal. Some very important interactions of gradient descent learning are exposed, providing conditions under which gradient descent will converge to an admissible solution in an associative memory structure. A layer of learning heuristics can be built upon the basic gradient descent learning algorithm to improve memory efficiency in terms of error rate, and therefore hardware requirements. A simulation study examines the effects of one such heuristic in the context of handwritten digit recognition.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125485066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When used as part of the control system for an agent, the architecture enables the agent to learn the functional semantics of its motor outputs and sensory inputs, and to acquire behavioral sequences by imitating other agents (learning by 'watching'). This involves attempting to recreate the sensory sequences the agent has been exposed to. The architecture scales well to multiple motor and sensory modalities, and to more complex behavioral requirements. The SAM architecture may also hint at an explanation of several features of the operation of the cerebral neocortex.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125601082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a multi-level backpropagation network (MLBPN) model as a classifier for practical pattern recognition systems. The described model reserves the benefits of the BPN and derives the extra benefits of this MLBPN with two fold: (1) the MLBPN can reduce the complexity of BPN, and (2) a speed-up of the recognition process is attained. The experimental results verify these characteristics and show that the MLBPN model is a practical classifier for pattern recognition systems.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127977354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The second involves the input nodes: by the examination of the connecting weights between the input nodes and the following hidden layer, we can determinate which features are actually relevant for our classification problem, and then eliminate the useless ones. Through the problem of recognising the French vowel /a/, we show that we can obtain a reduced structure that still can learn.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128177867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
