In this paper, we address the problem of discriminative dictionary learning (DDL), where sparse linear representation and classification are combined in a probabilistic framework. As such, a single discriminative dictionary and linear binary classifiers are learned jointly. By encoding sparse representation and discriminative classification models in a MAP setting, we propose a general optimiza...

valdis laan in [5] introduced an extension of strong flatness which is called weak pullback flatness. in this paper we introduce a new property of acts over monoids, called u-wpf which is an extension of weak pullback flatness and give a classification of monoids by this property of their acts and also a classification of monoids when this property of acts implies others. we also show that regu...

Let B be the generalized braid group associated to some finite complex reflection group W . We define a representation of B of dimension the number of reflections of the corresponding reflection group, which generalizes the Krammer representation of the classical braid groups, and is thus a good candidate in view of proving the linearity of these groups. We decompose this representation in irre...

Shape-based metrics measure how faithfully a drawing D represents the structure of graph G, using proximity S D. While some limited classes admit drawings (i.e., optimally shape-faithful drawings, where $$S = G$$ ), algorithms for general graphs have not been investigated. In this paper, we present first study graphs. First, conduct extensive comparison experiments popular layouts shape-based m...

A typical concept in quantum state analysis is based on the idea that states vicinity of some pure entangled share same properties, implying with a high fidelity must be entangled. States whose entanglement can detected this way are also called faithful. We prove structural result corresponding fidelity-based witnesses, resulting simple condition for faithfulness two-party state. For simplest c...

Purpose: The aim of this study is to investigate the impact IT on banking performance through RF AIT. Theoretical framework: Business companies and institutions strive work in a shorter amount time, which makes information technology an important necessary way reach their goals develop business day by day. It assumes that they have positive significant performance. Methodology: Data five major ...

We consider a formal model of stimulus encoding with a circuit consisting of a bank of filters and an ensemble of integrate-and-fire neurons. Such models arise in olfactory systems, vision, and hearing. We demonstrate that bandlimited stimuli can be faithfully represented with spike trains generated by the ensemble of neurons. We provide a stimulus reconstruction scheme based on the spike times...
