Dear Students,

Tomorrow Dr. Emanuele Cavenaghi and Dr. Francesco Canonaco will held the fourth and fifth seminars of the course.

Dr. Emanuele Cavenaghi will present his PhD thesis titled 'A causal perspective of Decision Making'. The seminar will explore how causal models can make recommender systems more reliable, explainable, and aligned with real-world decision-making. Through studies on bias, user-behavior simulation, and robust evaluation, it shows how causality enables a shift from correlations to truly informed choices with causes.

Dr. Francesco Canonaco will present his current research topic titled 'Roots Screening: One Shot Identification of Root Nodes in LiNGAM Models'. His presentation will introduce Roots Screening, a simple and fast method to detect all root nodes in a LiNGAM model in one step. The method is based on the mutual-information score used in DirectLiNGAM and shows that root nodes have a distinct behaviour that makes them easy to identify. This one-shot detection greatly reduces computation time, especially in high-dimensional settings like microbiome data. He will explain the idea behind the method and show results from experiments on synthetic networks.

Best Wishes,
Federico Pirola
