Submitted on Tuesday, 10/10/2023

Join us for the next seminar in the Insight SFI Research Centre for Data Analytics Visiting Researchers Programme taking place at Insight DCU. Guest speaker Dr Joe Naoum-Sawaya, Assistant Professor of Management Science at the Ivey Business School, London, Ontario, Canada, will discuss:

Optimization Models for learning Consumer Preferences

  • Date: Thursday 9th November 2023
  • Time: 10.30 – 11.30
  • Venue: Insight seminar room N206 (Marconi Building, DCU)
  • Registration: Eventbrite

Dr Naoum-Sawaya will present new models for consumer preference learning which is a critical task in numerous marketing and operational decisions. A commonly used data-driven approach for consumer preference learning is based on eliciting consumer choice preferences and fitting a function that ultimately provides a utility score for each consumer choice. A major issue in this approach is the noise in choice data that is due to the natural “irrationality” of consumers in their decision-making which leads to inaccuracies in the learned models. We upon ideas from machine learning and mathematical programming, and propose a robust preference elicitation model that guarantees robustness against feature noise (i.e., perturbations caused by consumer misconceptions) and label noise (i.e., response errors). For that, we present new optimization models that capture the specificity of consumer preference learning and discuss the results that show higher model accuracy as well as more detailed segmentation of consumers.

The Insight Visiting Researchers Programme provides an excellent platform for researchers to connect with leading experts in their field. The thought provoking presentations aim to enrich the knowledge and perspectives of researchers, fostering collaborations and inspiring innovative approaches in data analytics.
