We propose a novel approach to discover useful patterns from ill-defined decision tables with a real value decision and nominal conditional attributes. The proposed solution is based on a two-layered learning algorithm. In the first layer the preference relation between objects is approximated from the data. In the second layer the approximated preference relation is used to create three applic...

Competitive interactions between individuals are ubiquitous in human societies. Auctions represent an institutionalized context for these interactions, a context where individuals frequently make non-optimal decisions. In particular, competition in auctions can lead to overbidding, resulting in the so-called winner's curse, often explained by invoking emotional arousal. In this study, we invest...

Affinity propagation (AP) is a clustering method that can find data centers or clusters by sending messages between pairs of data points. Seed Affinity Propagation is a novel semisupervised text clustering algorithm which is based on AP. AP algorithm couldn’t cope up with part known data direct. Therefore, focusing on this issue a semi-supervised scheme called incremental affinity propagation c...

The Figure Independence Scale (FIS) assesses people's preference for abstract figures that represent uniqueness. As psychological manifestations of cultural values cohere among each other within a cultural system, the authors argue that preference for uniqueness, as a psychological manifestation of the value for independence, can be used as an indirect measure of this value. Four studies examin...

In this paper a descriptive extension of the expected utility model to account for various paradoxes is proposed using the concept of strength of preference. We deal with the case where probability of occurrence for each event is unknown. When we describe the degree of ignorance and uncertainty by the basic probability of Dempster-Shafer theory, the problem is how to represent the value of a se...

abstract successful presence of indian and pakistani rice in iran’s market due to having similar quality with the domestic rice, extensive advertisement, and good packaging has faced rice production in iran with a big challenge. assuming that the attractions of iranian consumers toward these imported rice varieties are a signal of changes in the preferences of the domestic consumers in favor of...

Although there are no scientific studies which evaluate psychotherapy for unwanted homosexual attraction (UHA) among adolescents, there are four studies that examine "sexual orientation change efforts"(SOCE) among adults which have been referenced to support legislative efforts to ban minors from receiving psychotherapy for UHA. This review critically examines each of those four studies. Pediat...

Collaborative filtering-based recommender systems exploit user preferences about items to provide them with recommendations. These preferences are generally ratings. However, choosing a rating is no easy task for any user; the rating scale is usually reduced and the rating values given by the users may be influenced by many factors. The ratings are thus not completely trustworthy. This paper is...

This paper addresses the problem of expressing preferences among nonfunctional properties of services in a Web service architecture. In such a context, semantic and non-functional annotations are required on service declarations and business process calls to services in order to select the best available service for each invocation. To cope with these multi-criteria decision problems, condition...

Preference learning has received increasing attention in both machine learning and information retrieval. The goal of preference learning is to automatically learn a model to rank entities (e.g., documents, webpages, products, music, etc.) according to their degrees of relevance. The particularity of preference learning might be that the training data is a set of pairwise preferences between en...
