Abstract: Recommender systems are ubiquitous: they connect us to jobs, news, media, and friends, fundamentally shaping our experiences. Two challenges in modern recommenders motivate much of my ongoing research: (i) how to carefully model user-item interactions that are essential for driving these systems; and (ii) how to combat unfairness and bias that are seemingly inherent in recommenders. In this talk I will present recent work in my lab on sequential hypergraphs to tackle the first challenge, and then highlight a series of works on combating bias. I'll conclude with thoughts on important challenges and next steps.
