On the irreducibility of Hurwitz spaces of coverings with an arbitrary number of special points

2013

In this paper we study Hurwitz spaces of coverings of Y with an arbitrary number of special points and with monodromy group a Weyl group of type D_d, where Y is a smooth, complex projective curve. We give conditions for which these spaces are irreducible.

A Hybrid Neural Network Architecture for Dynamic Scene Understanding

1997

A hyprdid (neural and symbolic) architecture allowing for a deep understanding of moving scenes is described. The architecture is based on a working and effective integration among three levels of representation of data coming out from external sensors.

Hypergraph imaging: an overview

2002

Hypergraph theory as originally developed by Berge (Hypergraphe, Dunod, Paris, 1987) is a theory of finite combinatorial sets, modeling lot of problems of operational research and combinatorial optimization. This framework turns out to be very interesting for many other applications, in particular for computer vision. In this paper, we are going to survey the relationship between combinatorial sets and image processing. More precisely, we propose an overview of different applications from image hypergraph models to image analysis. It mainly focuses on the combinatorial representation of an image and shows the effectiveness of this approach to low level image processing; in particular to seg…

Measuring the Novelty of Natural Language Text Using the Conjunctive Clauses of a Tsetlin Machine Text Classifier

2020

Most supervised text classification approaches assume a closed world, counting on all classes being present in the data at training time. This assumption can lead to unpredictable behaviour during operation, whenever novel, previously unseen, classes appear. Although deep learning-based methods have recently been used for novelty detection, they are challenging to interpret due to their black-box nature. This paper addresses \emph{interpretable} open-world text classification, where the trained classifier must deal with novel classes during operation. To this end, we extend the recently introduced Tsetlin machine (TM) with a novelty scoring mechanism. The mechanism uses the conjunctive clau…

Digital Vitruvius, or an elogy of the equilateral triangle

2012

On interpretation of an architectural project, triangle’s form generally refers both to plans of organic architecture and to fronts of Romanesque and Gothic churches. This wonderful form, that contains God’s eye, is, according to Vitruvius, the geometric generative principle of the Roman Theatre. Everybody knows that De Architectura arrived to us without images; in the past there were innumerable interpretations, from editio princeps (1486). A digital transcriptions, that follows side by side a Vitruvius’ book’s translation, highlights the compositional process that defines that the equilateral triangle is the geometric element that give origin to the composition of theatre.

Urban Landscape in the Graphic Representations of the Cathedral of Palermo

2017

The present study offers some reflections on the relationship between the cathedral of Palermo and the urban area in which it insists, regarding the indissoluble link with the landscape aspect that through the history offered a variety of perceptive suggestions, marked by the passage and presence of different dominations. The cognitive storytelling of the cathedral of Palermo is obtained through a graphic study on routes which provided of multiple images keeping the scar of time in the elaboration of orographic sections and perspective views and highlighting the role of perception in this changing combination of architecture and landscape.

A Stigmergic Guiding System to Facilitate the Group Decision Process

2012

The paper presents a stigmergic approach to engineer a guiding system to facilitate the complex problem of designing the group decision processes. The system aims to provide contextual, actionable recommendations based on the knowledge and past experience of its users as recorded in a collaborative working environment implemented around the concept of stigmergic systems. Through an agent-based socio-simulation experiment we have demonstrated already the feasibility of this approach. The paper illustrates how the simulation results are transferred into a guiding system that facilitates the group decision process design through iterative queries reformulations for the identification, represen…
