Using mathematical analyses and simulation experiments, we investigated the role of the maintained-discharge (base firing rate) parameter in this model. We developed an implementation that can take grayscale images as inputs and applied it to the types of visual stimuli used in a comprehensive suite of published physiological studies. We found that three empirical phenomena are closely associated with the maintained-discharge parameter: (A) the existence of inhibitory regions in the receptive fields of simple cells in V1, (B) the supersaturation effect in the contrast sensitivity curves, and (C) the narrowing/widening of the spatial-frequency tuning curves when the stimulus contrast decreases. The model predicts two patterns of these phenomena: One possibility is that a neuron can show A, B, and widening (C); the other possibility is to show not-A, not-B, and narrowing (C). This interdependence is a potentially falsifiable prediction of the divisive normalization model.","PeriodicalId":415083,"journal":{"name":"International Conference on Bio-inspired Information and Communications Technologies","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131827189","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}

However, thermograms exhibit large shape variations, and the sample size is typically small. Therefore, it is important to extract robust characterization of thermograms representing the clinical status for further study. The current study identifies the representative heat capacity profiles from functional principle components which are derived from the bootstrap distribution of the deepest heat capacity function according to the functional data depth, instead of the original thermogram data set. 71 thermograms are obtained from two groups (healthy, cervical carcinoma), and functional PCA are conducted with the original thermogram data set and the bootstrap data set of the deepest heat capacity functions. Examining the first three PCs of the two groups between the two data sets, the bootstrap data set shows more distinctive difference in modes of variation between the two groups in comparison with the original thermogram data set, and the representative heat profiles are reconstructed with the PCs which are derived from the bootstrap sample sets. 90% confidence intervals of the representative heat profiles can be directly obtained from the same bootstrap set.","PeriodicalId":415083,"journal":{"name":"International Conference on Bio-inspired Information and Communications Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122796509","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}

Here, we describe a novel Deconvolutional Competitive Algorithm (DCA), which explicitly learns non-redundant hierarchical representations by enabling competition both within and between sparse coding layers. All layers in a DCA are trained simultaneously and all layers contribute to a single image reconstruction. Because the entire hierarchy in a DCA comprises a single dictionary, there is no need for dimensionality reduction between layers, such as MAX pooling. We show that a 3-layer DCA trained on short video clips exhibits a clear segregation of image content, with features in the top layer reconstructing large-scale structures while features in the middle and bottom layers reconstruct progressively finer details. Compared to lower levels, the representations at higher levels are more invariant to the small image transformations between consecutive video frames recorded from hand-held cameras. The representation at all three hierarchical levels combine synergistically in a whole image classification task. Consistent with psychophysical studies and electrophysiological experiments, broad, low-spatial resolution image content was generated first, primarily based on sparse representations in the highest layer, with fine spatial details being filled in later, based on representations from lower hierarchical levels.","PeriodicalId":415083,"journal":{"name":"International Conference on Bio-inspired Information and Communications Technologies","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124570134","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 return, developing such self-organising robotic systems can lead to a better understanding of natural collective systems. By unifying the communication channels of the natural and artificial agents these two collective systems can be merged into one bio-hybrid society. In this work we demonstrate the feasibility of such a bio-hybid society by introducing a simple one-dimensional model. A set of patches forms a one-dimensional arena, each patch represents a stationary robot, which is controlled by an AHHS (Artificial Homeostatic Hormone System) control software. The stationary robots are able to produce different types of environmental stimuli. Simulated bees react diversely to the different stimuli types. An evolutionary computation algorithm changes the properties of the AHHS and defines the interactions between the robots and their properties of stimuli emission. The task is an aggregation of simulated bees at a predefined aggregation spot. We demonstrate that an evolved AHHS is a very feasible tool for controlling these stationary robots. Furthermore we show that an AHHS even works robustly in different setups and dynamic environments even though the controller was not specially evolved for these purposes.","PeriodicalId":415083,"journal":{"name":"International Conference on Bio-inspired Information and Communications Technologies","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129327505","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}
