Oja","doi":"10.1109/IJCNN.1991.170648","DOIUrl":"https://doi.org/10.1109/IJCNN.1991.170648","url":null,"abstract":"The problem of approximating a real function f of L variables, given only in terms of its values y/sub 1/,. . .,y/sub M/ at a small set of sample points x/sub 1/,. . .,x/sub M/ in R/sup L/, is studied in the context of multilayer neural networks. Using the theory of reproducing kernels of Hilbert spaces, it is shown that this problem is the inverse of a linear model relating the values y/sub m/ to the function f itself. The authors consider the least-mean-square training criterion for nonlinear multilayer neural network architectures that learn the training set completely. The generalization property of a neural network is defined in terms of function reconstruction and the concept of the optimally generalizing neural network (OGNN) is proposed. It is a network that minimizes a criterion given in terms of the true error between the original function f and the reconstruction f/sub 1/ in the function space, instead of minimizing the error at the sample points only. As an example of the OGNN, a projection filter (PF) criterion is considered and the PFGNN is introduced. The network is of the two-layer nonlinear-linear type.<<ETX>>","PeriodicalId":211135,"journal":{"name":"[Proceedings] 1991 IEEE International Joint Conference on Neural Networks","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129973990","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 proposed architecture utilizes compact solid modules for single-layer feedforward networks, which may be cascaded for MBAM. Instead of analog interconnection weights the inner-product scheme stores input and output patterns. For binary input and output patterns this inner-product scheme requires binary spatial light modulators only, and is scalable to very large-size implementations. Unlike optical neural networks for one-dimensional patterns, multifocus holograms and lenslet arrays become essential components in these modules. The performance of the MBAM was demonstrated by an electrooptic inner-product implementation for the exclusive-OR problem.<<ETX>>","PeriodicalId":211135,"journal":{"name":"[Proceedings] 1991 IEEE International Joint Conference on Neural Networks","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125650628","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}

It uses as inputs a small number of waveform samples and extracted parameters. The network has been found to perform better than a rate-based scheme similar to those used in commercially available implantable cardioverter-defibrillators in its ability to distinguish normal rhythms from arrhythmias. It shows, in addition, a certain ability to discriminate between a larger number of rhythms: in particular, between sinus tachycardia and slow ventricular tachycardia and between slow and fast ventricular tachycardias.<<ETX>>","PeriodicalId":211135,"journal":{"name":"[Proceedings] 1991 IEEE International Joint Conference on Neural Networks","volume":"323 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131969103","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 platform provides the user with an easy-to-learn, easy-to-use operating environment for creating, training, editing, and enhancing neural-network-based expert systems. The underlying neural logic network (NELONET) has been shown to be capable of doing logical inferencing and is used in two large-scale-operation expert systems. Building on top of the X-window system and the OPENLOOK user interface, GENES inherits the select-and-perform operation strategy for neural network objects. The system's knowledge base contains simple network elements that correspond to rules in a conventional system. During the inference process, these network elements are linked up dynamically to form a large neural network which will operate according to the NELONET activation rules.<<ETX>>","PeriodicalId":211135,"journal":{"name":"[Proceedings] 1991 IEEE International Joint Conference on Neural Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130859532","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}

It is based on the assumption that cognition is the result of neural activities taking place in a natural or artificial neural network (ANN). In the model presented the network is not embedded into a linguistic environment but rather is physically coupled to the environment via sensors and effectors. From an epistemological as well as computer science perspective this is a radical step which has many very important implications. In computational neuroepistemology this kind of connectionism is called radical connectionism or radical neural computing. The ANN has to be physically embedded into its environment. This means that the communication between the system and its environment takes place via effectors and sensors. No symbols are involved in this process of interaction. A recurrent topology is required which ensures a nonlinear and nontrivial behavior. Technical details are given on the simulation of the environment, of the interactions between the artificial cognitive system(s) and the environment and on the implementation of the simulation.<<ETX>>","PeriodicalId":211135,"journal":{"name":"[Proceedings] 1991 IEEE International Joint Conference on Neural Networks","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115284749","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}

If the code primitives are given in advance (as biologically), it can be shown that the connection weights between input and output layers are just these primitives, while the lateral connection weights are formed by their inner products. In order to gain insight into the detailed nature of the network, Hebbian and anti-Hebbian rules are chosen for governing the modifications of feedforward and lateral connection weights, respectively. When the network is fed with random noises, it can self-organize according to these learning rules to develop masks resembling nonorthogonal receptive fields of simple cortical cells, as opposed to those models based on principal component analysis which seek to yield orthogonal feature detectors. At the same time it can perform optimal nonorthogonal image coding with respect to the code primitives being formed.<<ETX>>","PeriodicalId":211135,"journal":{"name":"[Proceedings] 1991 IEEE International Joint Conference on Neural Networks","volume":"89 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120991029","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}
