Thomas Kolb
Predoc Researcher
Thomas Kolb conducting research as part of his Ph.D. on the subject of long-term dynamics of bias and fairness in cross-domain recommender Systems. To analyze these dynamics in a real-world environment we work together with a company within the domain of news, books, and lifestyle. The exploration of long-term dynamics in this field has immense potential for the development of fairer recommender systems. He firmly believes in the significance of providing the research community with fresh insights to foster the creation of responsible and fair recommender systems.
