The work presented deals with a test methodology based on adding some extra circuitry to every cell of a regular ACNN. This methodology is just an initial proposal for taking an advantage of the network regularity to perform a global test that can be externally interpreted and, hence, has potential application for reconfiguring the network.<<ETX>>","PeriodicalId":142909,"journal":{"name":"IEEE International Workshop on Cellular Neural Networks and their Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132363852","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}

By use of the state-space concept the system theoretical approach is applicable to nonlinear input-output systems, too. Neural networks, which are highly structured systems, are built up of interconnected identical nonlinear components of a very simple type. The availability of VLSI technology has had a great impact on the development of these electronic cellular structures. The classical theory of time systems is not well-adapted for analysing such 'cellular systems' varying in space and time. The authors present a conception of space-time systems developed by Wunsch (1975, 1977), and show that this concept is very suitable for a system-theoretical description of the class of cellular neural networks discovered by L.O. Chua and L. Yang (1988).<<ETX>>","PeriodicalId":142909,"journal":{"name":"IEEE International Workshop on Cellular Neural Networks and their Applications","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127092888","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 desirability of a self organising algorithm which can learn an internal representation for use in a pattern recogniser is shown. Using such an algorithm, subspace methods are brought together with an associative memory to form a pattern recogniser which employs unsupervised learning. The representation used for signal pattern clusters is based on topologically ordered units, each of which can label a complex area of pattern space. An adaption algorithm is given and shown to be insensitive to the variation in vector magnitudes which is found within a typical training set. A number of examples are given showing clustering of real grey scale, visual data and the reconstruction of exemplars using adaptive feedback. The application of this to vector quantisation and noise removal is demonstrated.<<ETX>>","PeriodicalId":142909,"journal":{"name":"IEEE International Workshop on Cellular Neural Networks and their Applications","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116631462","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}

Concerns the use of stable analog cellular neural networks (CNN) for image processing. CNN architecture can be treated as a space-invariant iterative nonlinear filter. The authors compare CNNs and other techniques in image processing. The analysis is performed for two kinds of tasks for which nonlinear filters are commonly used: noise suppression and edge detection. Two synthesized test images, 64*64 pixels each, are used in experiments. One consists of solid blocks of different shapes and the other contains thin lines and sharp corners. The images are added with zero-mean Gaussian noise and impulsive noise. The efficiency of noise removal is examined. The limiter type M filter, a type of median filter, is considered. Edge detection by various filters and operators is compared.<<ETX>>","PeriodicalId":142909,"journal":{"name":"IEEE International Workshop on Cellular Neural Networks and their Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133561672","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}
