This paper further develops the theory of maptrees, introduced in [?]. There exist well-known methods, based upon combinatorial maps, for topologically complete representations of embeddings of connected graphs in closed surfaces. Maptrees extend these methods to provide topologically complete representations of embeddings of possibly disconnected graphs. The focus of this paper is the use of m...

Visual attribute-based learning has shown a big impact on many computer vision problems in recent years. Albeit its usefulness, most of works only focus on predicting either the presence or the strength of pre-defined attributes. In this paper, we discuss how to automatically learn visual attributes that characterize an object class. Starting from the images of an object class that are collecte...

In this paper, an innovative approach is proposed for integration of descriptions regarding multimedia content collections. The proposed method has been applied to audio– visual content clusterings, which were extracted using different algorithms. With the support of low level features, obtained with further algorithms, all input clusterings are characterized and then merged in a new integrated...

sets as the basis for visualizing ecoregion maps.1,2 Ecoregions are areas containing similar environmental conditions that are classified for particular purposes. For example, the US Department of Agriculture publishes a map of Plant Hardiness Zones, which divides the US into different ecoregions so that gardeners can select appropriate plants and shrubs for their particular area. The ecoregion...

We present a novel, simple, unsupervised method for characterizing the semantic relations that hold between nouns in noun-noun compounds. The main idea is to discover predicates that make explicit the hidden relations between the nouns. This is accomplished by writing Web search engine queries that restate the noun compound as a relative clause containing a wildcard character to be filled in wi...

We analyze qubit channels by exploiting the possibility of representing two-level quantum systems in terms of characteristic functions. To do so, we use functions of non-commuting variables (Grassmann variables), defined in terms of generalized displacement operators, following an approach which resemble the one adopted for continuous–variable (Bosonic) systems. It allows us to introduce the no...

Integrating geological concepts, such as relative positions and proportions of the different lithofacies, is of highest importance in order to render realistic geological patterns. The truncated plurigaussian simulation method provides a way of using both local and conceptual geological information to infer the distributions of the facies and then those of hydraulic parameters. The method (Le L...

in this paper we characterize hyper mv -algebras in which 0 or1 are scalar elements . we prove that any nite hyper mv -algebra that 0is a scaler element in it, is an mv -algebra. finally we characterize hypermv -algebras of order 2 and order 3.

P system is a natural computing model inspired by behavior of living cells and their membranes. We show that (semi-)uniform families of P systems with active membranes can solve in polynomial time exactly the class of problems PSPACE. Consequently, these P systems are computationally equivalent (w.r.t. the polynomial time reduction) to standard parallel machine models as PRAM and the alternatin...
