A churn prediction dataset from the telecom sector: a new benchmark for uplift modeling

1 code implementation12 Dec 2023 Théo Verhelst, Denis Mercier, Jeevan Shrestha, Gianluca Bontempi

Uplift modeling, also known as individual treatment effect (ITE) estimation, is an important approach for data-driven decision making that aims to identify the causal impact of an intervention on individuals.

A data-science pipeline to enable the Interpretability of Many-Objective Feature Selection

1 code implementation30 Nov 2023 Uchechukwu F. Njoku, Alberto Abelló, Besim Bilalli, Gianluca Bontempi

The methodology supports the data scientist in the selection of an optimal feature subset by providing her with high-level information at three different levels: objectives, solutions, and individual features.

Between accurate prediction and poor decision making: the AI/ML gap

no code implementations3 Oct 2023 Gianluca Bontempi

This paper argues that AI/ML community has taken so far a too unbalanced approach by devoting excessive attention to the estimation of the state (or target) probability to the detriment of accurate and reliable estimations of the utility.

Uplift vs. predictive modeling: a theoretical analysis

1 code implementation21 Sep 2023 Théo Verhelst, Robin Petit, Wouter Verbeke, Gianluca Bontempi

Despite the growing popularity of machine-learning techniques in decision-making, the added value of causal-oriented strategies with respect to pure machine-learning approaches has rarely been quantified in the literature.

Adversarial Learning in Real-World Fraud Detection: Challenges and Perspectives

no code implementations3 Jul 2023 Danele Lunghi, Alkis Simitsis, Olivier Caelen, Gianluca Bontempi

Although early results of adversarial machine learning indicate the huge potential of the approach to specific domains such as image processing, still there is a gap in both the research literature and practice regarding how to generalize adversarial techniques in other domains and applications.

A review and comparison of strategies for multi-step ahead time series forecasting based on the NN5 forecasting competition

no code implementations16 Aug 2011 Souhaib Ben Taieb, Gianluca Bontempi, Amir Atiya, Antti Sorjamaa

To attain such an objective, we performed a large scale comparison of these different strategies using a large experimental benchmark (namely the 111 series from the NN5 forecasting competition).
