One of crucial tasks in machine learning is the evaluation of the quality of attributes. For that purpose a number of measures have been developed that estimate the usefulness of the attribute for predicting the target variable. We describe separately measures for classification (which are appropriate also for relational problems) and for regression. Most of the measures estimate the quality of...

As Model-Based Engineering (MBE) starts to be effectively used, some of its constituent disciplines such as Domain Specific Modeling and Metamodeling are becoming quite popular. Metamodels play a cornerstone role in these approaches, not only for defining Domain Specific Languages but also for specifying all kinds of artifacts involved in MBE. However, there is a lack of appropriate quality mod...

Living in satisfying urban environments is important for an individual’s well-being. In order to create such environments, planners, designers, and policy makers need to understand the structures that cause residents to feel satisfied with their environments. This paper focuses on the perceived quality of urban residential environments: dwellings and neighborhoods. First, literature review w...

In this Appendix, we extend the model to the case where goods are characterized by multiple attributes. We then study in detail the case where goods differ along two quality attributes. As in Section 2, a consumer evaluates all N > 1 goods in a choice set Cchoice ≡ {qk}k=1,...,N . Each good k is a vector qk = (q1k, . . . , qmk, pk) ∈ R of m > 1 quality attributes, where qik (i = 1, . . . ,m) me...

Varietal purity and proportions of grains with brown spots, fissured grains, chalky grains andwhole grains in a rice sample are important grain quality attributes influencing consumers'preference and price but little information exist on how these grain quality attributes are affectedby biophysical factors and pre-harvest practices. Several authors have studied in isolation theeffect of biophys...

Trustworthiness of Internet-based software systems, apps, services and platform is a key success factor for their use and acceptance by organizations and end-users. The notion of trustworthiness, though, is subject to individual interpretation and preference, e.g., organizations require confidence about how their business critical data is handled whereas end-users may be more concerned about us...

This paper proposes a Fuzzy Group Analytical Hierarchy Process approach for assessing the quality of software, with judgments by a group of experts at different levels. The international standard of software quality attributes, ISO/IEC9126-1:2001 which comprises of 6 criteria with 27 subcriteria, is applied as the attributes of software quality. Regarding the prioritization method, the modified...

This paper presents an experience of educational podcasting set up at the University of Bergamo (Italy), and derives from that experience some remarks upon the quality of podcasting services, in order to promote the definition of guidelines on podcasting quality. We discuss three main attributes of a podcasting environment: quality of the production environment (recording and editing), quality ...
