Multi-label classification using boolean matrix decomposition
2012
This paper introduces a new multi-label classifier based on Boolean matrix decomposition. Boolean matrix decomposition is used to extract, from the full label matrix, latent labels representing useful Boolean combinations of the original labels. Base level models predict latent labels, which are subsequently transformed into the actual labels by Boolean matrix multiplication with the second matrix from the decomposition. The new method is tested on six publicly available datasets with varying numbers of labels. The experimental evaluation shows that the new method works particularly well on datasets with a large number of labels and strong dependencies among them.
A multi-physics integrated approach to breeding blanket modelling and design
2019
Abstract Often, for the design of a component, several kinds of analyses are needed. Even more frequently, the different fields of study, to be taken into account for the design verification, have to be examined minutely until the final results are satisfying. Furthermore, when geometry modifications are required, for instance to fulfill the component functions, the analyses cycle has to be restarted and an iterative process has to be carried out. This procedure may be time-consuming and herald of errors, in particular if it is demanded to the human activity. Therefore, it is more convenient for the scientific community to adopt a numerical tool that can combine various computational codes.…

The link between colour and emotion and its possible similarity across cultures are questions that have not been fully resolved. Online, 711 participants from China, Germany, Greece and the UK associated 12 colour terms with 20 discrete emotion terms in their native languages. We propose a machine learning approach to quantify (a) the consistency and specificity of colour–emotion associations and (b) the degree to which they are country-specific, on the basis of the accuracy of a statistical classifier in (a) decoding the colour term evaluated on a given trial from the 20 ratings of colour–emotion associations and (b) predicting the country of origin from the 240 individual colour–emotion a…
Adaptation of the Presentation in a Multi-tenant Web Information System
2012
We introduced a Web Information System (WIS) adaptation architecture that is based on Software as a Service (SaaS) ideas. It includes adaptation components, which allow adaptation in two levels: the organizations and the users get their own adapted instance of the WIS. The user interface in case of multi-tenancy should be dynamically adapted according to the particular organization and user. The same application component that contains a set of fields, controls and other interface elements should be varied according to the usage context. In this paper we provide a method for adapting the user interface within the proposed adaptation architecture that uses a set of rules describing the seque…
THE EFFECT OF INBOUND, OUTBOUND AND COUPLED INNOVATION ON PERFORMANCE
2012
The focus of this paper is on exploring linkages among Open Innovation practices and firm performance. While, in the last ten years, a certain amount of papers facing such issue has been published, most of them treat inbound, outbound, and coupled innovation practice processes separately respect to different dimensions of innovation and financial performance. We argue that the concurrent influence of specific Open Innovation practices on both innovation and economic-financial firms' performance has not been investigated so far into the literature and it is of primary managerial importance. We empirically test our framework on a sample of 105 companies listed on the Industrial Machinery and…
A Concurrent Neural Classifier for HTML Documents Retrieval
2003
A neural based multi-agent system for automatic HTML pages retrieval is presented. The system is based on the EαNet architecture, a neural network having good generalization capabilities and able to learn the activation function of its hidden units. The starting hypothesis is that the HTML pages are stored in networked repositories. The system goal is to retrieve documents satisfying a user query and belonging to a given class (i.e. documents containing the word “football” and talking about “Sports”). The system is composed by three interacting agents: the EαNet Neural Classifier Mobile Agent, the Query Agent, and the Locator Agent. The whole system was successfully implemented exploiting t…
El análisis del discurso oral y su enseñanza
2015
Speaking a language does not only mean mastering the rules that govern its grammar, but also requires knowing how to communicate, as well as being able to interact efficiently in this language, exchanging and interpreting information in different registers and language varieties. It is necessary, therefore, to teach Pragmatics, understood as the analysis and reflection on the usage and on the strategic mechanisms displayed when speaking (acting), especially when the interaction takes place in specific communicative circumstances. Learning the oral component of a language must prepare students for the analysis of speech samples. By learning the oral aspects, students acquire some skills and …
Preliminary design of the top cap of DEMO Water-Cooled Lithium Lead breeding blanket segments
2020
Abstract Within the framework of EUROfusion R&D activity, a research campaign has been carried out at the University of Palermo, in close cooperation with ENEA labs, in order to preliminary design the top cap foreseen for the DEMO Water-Cooled Lithium Lead (WCLL) breeding blanket segments. Due to the high heat and pressure loads acting on such component, its design results particularly demanding and a specific multi-physics approach is needed, covering several aspects from thermal-hydraulics to structural assessments. Preliminary detailed CAD model of the cap integrated into the upper region of the WCLL breeding blanket outboard central segment has been set-up, equipped with proper cooling …
Classification and retrieval on macroinvertebrate image databases
2011
Aquatic ecosystems are continuously threatened by a growing number of human induced changes. Macroinvertebrate biomonitoring is particularly efficient in pinpointing the cause-effect structure between slow and subtle changes and their detrimental consequences in aquatic ecosystems. The greatest obstacle to implementing efficient biomonitoring is currently the cost-intensive human expert taxonomic identification of samples. While there is evidence that automated recognition techniques can match human taxa identification accuracy at greatly reduced costs, so far the development of automated identification techniques for aquatic organisms has been minimal. In this paper, we focus on advancing …
UML design and AWL programming for reconfigurable control software development of a robotic manipulator
2006
The goal of the presented research is to face the topic of reconfigurable control software development in a concrete fashion, i.e., by presenting a control software system development approach which has been used for a specific, although easy to be generalized, robotized manufacturing cell component. In particular, a methodology for the control software development of a planar robot (2-degrees of freedom) is presented, from the conceptual design to the actual implementation. The methodology suggests UAL and object-oriented modeling and programming techniques for the design phase, while AWL programming language run by a PLC for the implementation phase. The analysis has been conducted consid…
