Usage Context-Based Design (UCBD) is an area of growing interest within the design community. Usage context is the set of scenarios in which a product (or service) is to be used, including the environments in which the product is used, the types of tasks the product performs, and the conditions under which the product is purchased and operates. It is proposed in this work that in choice modelin...

We introduce tiered clustering, a mixture model capable of accounting for varying degrees of shared (context-independent) feature structure, and demonstrate its applicability to inferring distributed representations of word meaning. Common tasks in lexical semantics such as word relatedness or selectional preference can benefit from modeling such structure: Polysemous word usage is often govern...

Model adaptation is a process of modifying a model trained with a large amount of training data from the source domain to adapt a speci c similar target domain by using a small amount of adaptation data regarding the target domain. Bayesian hierarchical modeling is well known as a general tool for model adaptation and multi-task learning, and widely used in various areas such as marketing, ecol...

Considerably less research has been done on modeling freight demand with disaggregate discrete models than on modeling passenger demand. The principal reason for this imbalance is the lack of freight demand data. Freight demand characteristics are expensive to obtain and are sometimes confidential. This paper analyzes the freight demand characteristics that drive modal choice by means of a larg...

The paper presents some results obtained in searching a new axiomatic foundation for the partial comparability theory (PCT) in the frame of non conventional preference modeling. The basic idea is to define an extended preference structure able to represent lack of information, uncertainty, ambiguity, multidimensional and conflicting preferences, using formal logic as the basic formalism. A four...

Is the impact of sales promotion on consumer perception mediated by its hedonic and utilitarian benefits in the context of Indian consumers?  Is gender having a moderating impact on the relationship between the benefits of sales promotion and consumer perception?  Authors examined both questions using a partial least square structural equation modeling (PLS-SEM). Findings revealed that hedonic ...

In this paper, we investigate group decision making problems with multiple types of linguistic preference relations. The paper has two parts with similar structures. In the first part, we transform the uncertain additive linguistic preference relations into the expected additive linguistic preference relations, and present a procedure for group decision making based on multiple types of additiv...

Computational methods for discovering the preferences of individuals are useful in many applications. In this paper, we propose a method for learning valued preference structures, using a natural extension of so-called pairwise classification. A valued preference structure can then be used in order to induce a ranking, that is a linear ordering of a given set of alternatives. This step is reali...
