Theoretical Modeling of the Iterative Properties of User Discovery in a Collaborative Filtering Recommender System
The closed feedback loop in recommender systems is a common setting that can lead to different types of biases. Several studies have dealt with these biases by designing methods to mitigate their effect on the recommendations. However, most existing studies do not consider the iterative behavior of the system where the closed feedback loop plays…
Modeling and Counteracting Exposure Bias in Recommender Systems
What we discover and see online, and consequently our opinions and decisions, are becoming increasingly affected by automated machine-learned predictions. Similarly, the predictive accuracy of learning machines heavily depends on the feedback data that we provide them. This mutual influence can lead to closed-loop interactions that may cause unknown biases which can be exacerbated after…
Explainable Active Learning Strategy For Recommender Systems
Recommender System technologies are witnessing a revolutionary era these days. They are growing more and more important since they help in the discovery and promotion of products, books, news, music, movies, courses, restaurants, etc. One major problem of Recommender Systems is that the most accurate models tend to be black boxes, whose results cannot be…
