Choice-based conjoint analysis builds models of consumer preferences over products with answers gathered in questionnaires. Our main goal is to bring tools from the machine learning community to solve this problem more efficiently. Thus, we propose two algorithms to quickly and accurately estimate consumer preferences.

To improve consumer behaviour knowledge it is very important to collect information about consumer characteristics and preferences. This is possible at events such as “Civintas”, an Italian quality food exhibition that promotes production linked to a specific territory, such as DOC (Controlled Designation of Origin) wines. The 1997-2000 editions gave us the opportunity to gather information thr...

Empirical studies of consumer preferences for seafood ecolabels are relatively few, and typically address choices among labeled and non-labeled products of the same seafood species. Given that consumers often express strong preferences for certain seafood species, however, a more relevant assessment of consumer preferences would allow for choices among different seafood products of similar proc...

In e-commerce, for some cases the service requested by the consumer cannot be fulfilled by the producer. In such cases, service consumers and producers need to negotiate their service requirements and offers. Whereas some multiagent negotiation approaches treat the price as the primary construct for negotiation, we consider that the service content is as much important as the price. Therefore, ...

Understanding and modeling human preferences is one of the key problems in applications ranging from marketing to automated recommendation. In this paper, we focus on learning and analyzing the preferences of consumers regarding food products. In particular, we explore machine learning methods that embed consumers and products in an Euclidean space such that their relationship to each other mod...

This paper proposes a model featuring the heterogeneity of consumer preferences and analyzes the multiple equilibrium of retail formats by building a map of the relationships between consumer heterogeneity and retail formats. The key questions analyzed in this paper are how the retailer adjusts its combination of marketing elements through repositioning and how innovation in retail formats is i...
