It is shown that the set of such networks is non-void for any template structure and that bifurcations of equilibria correspond to either vanishing or shrinking of cells in both complexes. Both topological representations provide an intuitive description of the geometrical features underlying the network dynamics.<<ETX>>","PeriodicalId":248898,"journal":{"name":"Proceedings of the Third IEEE International Workshop on Cellular Neural Networks and their Applications (CNNA-94)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121446796","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}

{"title":"An approach to local diffusion and global propagation in 1-dim. cellular neural networks","authors":"Patrick Thiran, G. Setti","doi":"10.1109/CNNA.1994.381653","DOIUrl":"https://doi.org/10.1109/CNNA.1994.381653","url":null,"abstract":"Summary form only given, as follows. We study the phenomena of local diffusion and global propagation in a one-dimensional CNN described by the space-invariant A-template A = [A/sub -1/ A/sub 0/ A/sub 1/]. Roughly speaking, a CNN behaves in a local diffusion mode when two distant cells do not influence each other if the states of a number r of adjacent cells located between these two cells have reached some value. It behaves in a global propagation mode otherwise, i.e. when one of these two cells can always influence the other one, whatever the value of the state of r adjacent cells located in between these two cells. We can then compute the values of the template parameters for which the CNN has one of these behaviors. The distinction between these two methods of information processing is a radical one that has many practical consequences on: stability; the influence of boundary conditions; the dependence of the number of stable equilibria on the number of cells; the existence of limit cycles; and on the lengths of transients. For example, we can prove that the number of stable equilibria grows exponentially with the number of cells if and only if the CNN has a local diffusion behavior. If it operates in a global propagation mode, this is no longer true, but periodic solutions (one of which can be explicitly computed) are then present for some types of boundary conditions.<<ETX>>","PeriodicalId":248898,"journal":{"name":"Proceedings of the Third IEEE International Workshop on Cellular Neural Networks and their Applications (CNNA-94)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128643701","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}

Such a problem exhibits a partitioned control structure and is usually solved using preplanned routing mechanisms for slow varying flows. Here, we consider a Markov decision process modelling of the entities requiring admission and routing through the network under a setting allowing the slotted processing, extending a previous research (Murgu et al., 1994) done for a queueing system modelled as Brownian control problem. Using an idea of certainty equivalence principle, we map the local control scheme into a recurrent adaptive algorithm in which a learning mechanism is included. Finally, a numerical experiment with medium sized network is considered and the main conclusions are reported.<<ETX>>","PeriodicalId":248898,"journal":{"name":"Proceedings of the Third IEEE International Workshop on Cellular Neural Networks and their Applications (CNNA-94)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126636749","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}

We examine the validity of one plausible measure of the robustness to random template variations: the minimum absolute value of the current into the capacitor taken over all possible binary state patterns divided by the norm of the template elements. While this measure can be proven to be a valid indicator of robustness for linear threshold templates, its predictive power on the more dynamically complex CCD template is mixed. In some cases, an estimate of the error rate based upon this measure matches remarkably well with the results of numerical simulations. In others, this measure of robustness predicts that one template is more robust than another, while numerical simulations indicate that the opposite is true.<<ETX>>","PeriodicalId":248898,"journal":{"name":"Proceedings of the Third IEEE International Workshop on Cellular Neural Networks and their Applications (CNNA-94)","volume":"772 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124602958","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}
