Learning Product Characteristics and Consumer Preferences from Search Data
Luis Armona,Gregory Lewis,Georgios Zervas +2 more
- 18 Jul 2021
TL;DR: In this paper, the authors extend a machine learning approach (Bayesian Personalized Ranking) that allows to jointly learn latent product characteristics and consumer preferences from search data, and show how this can be combined with existing demand estimation approaches to predict demand.
