Preference learning has recently received a lot of attention within the machine learning field, concretely learning by pairwise comparisons is a well-established technique in this field. We focus on the problem of learning the overall preference weights of a set of alternatives from the (possibly conflicting) uncertain and imprecise information given by a group of experts into the form of inter...

When faced with complex choices, users refine their own preference criteria as they explore the catalogue of options. In this paper we propose an approach to preference elicitation suited for this scenario. We extend Coactive Learning, which iteratively collects manipulative feedback, to optionally query example critiques. User critiques are integrated into the learning model by dynamically ext...

Robert Sugden has recently elaborated upon the case for a normative standard of freedom as “opportunity” that is supposed to cope with the problem of how to realign normative economics – with its traditional rational choice orientation – with behavioral economics. His standard, though, presupposes that people respond to uncertainty about their own future preferences by dismissing any kind of se...

For some multi-criteria decision aiding methods, the relative ranks of two actions may be inverted when the original set is altered. This phenomenon is known as rank reversal. In this contribution, we formalise rank reversal for the Promethee II method and derive the exact conditions for its occurrence when one ore more actions are added or removed from/to the original set. These conditions eve...

Purpose: To assess the primary visual disability in patients with cataract and to evaluate their preference regarding the visual outcome after surgery. Materials and Methods: 120 patients (66 males, mean age 76.3 years, mean best corrected visual acuity 5.2/10 binocularly) participated. Perception regarding the primary visual disability related to cataract and preference of visual outcome after...

In this paper we introduce the notion of classical quasi-primary submodules that generalizes the concept of classical primary submodules. Then, we investigate decomposition and minimal decomposition into classical quasi-primary submodules. In particular, existence and uniqueness of classical quasi-primary decompositions in finitely generated modules over Noetherian rings are proved. More...

the relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. this study investigates host prefer-ence of the polyphagous hover fly syrphus ribesii (diptera: syrphidae) and compares it with some components of its offspring`s performance. females and offspring were tested on six naturally used aphid hosts (blackberry...

this study compared the use of interpersonal and mass media channels of communication among rural farmers in kogi state, nigeria. the specific objectives were to describe the socio economic characteristics of the farmers, determine the influence of socioeconomic characteristics on the usage of interpersonal and media channels, ascertain farmers’ level of awareness of interpersonal and media cha...

background diabetes is a common problem with severe complications. the control of diabetes needs a close and honest relationship between patients and health professionals. the views of these two groups might influence the professional relationship. objectives the purpose of this study was to identify the views of diabetic patients versus the views of diabetic care professionals on the content o...

In this work, we give an overview of our participation in the TREC 2014 Contextual Suggestion Track. To address the retrieval of attraction places, we propose a fuzzy-based document combination approach for preference learning and context processing. We use the open web in our submission and make use of both criteria users preferences and geographical location criteria.
