• Abstract: Nowadays, recommendation systems have become crucial to online platforms, shaping user exposure by accurate preference modeling. However, such an exposure strategy can also reinforce users' existing preferences, leading to a notorious phenomenon named filter bubbles. Given its negative effects, such as group polarization, increasing attention has been paid to exploring reasonable measures to filter bubbles. However, most existing evaluation metrics simply measure the diversity of user exposure, failing to distinguish between algorithmic preference modeling and actual information confinement. In view of this, we introduce Bubble Escape Potential (BEP), a behavior-aware measure that quantifies how easily users can escape from filter bubbles. Specifically, BEP leverages a contrastive simulation framework that assigns different behavioral tendencies (e.g., positive vs. negative) to synthetic users and compares the induced exposure patterns. This design enables decoupling the effect of filter bubbles and preference modeling, allowing for more precise diagnosis of bubble severity. We conduct extensive experiments across multiple recommendation models to examine the relationship between predictive accuracy and bubble escape potential across different groups. To the best of our knowledge, our empirical results are the first to quantitatively validate the dilemma between preference modeling and filter bubbles. What's more, we observe a counter-intuitive phenomenon that mild random recommendations are ineffective in alleviating filter bubbles, which can offer a principled foundation for further work in this direction.

  We develop a more refined definition of homogenization and the filter bubble effect by decomposing them into two key metrics. We then use a novel agent-based simulation framework that enables a holistic view of the impact of recommendation systems on homogenization and filter bubble effects. We introduce two new recommendation algorithms that take a more nuanced approach by accounting for both types of diversity.

• Generative Slate Recommendation with Reinforcement Learning [49.75985313698214]
  reinforcement learning algorithms can be used to optimize user engagement in recommender systems. However, RL approaches are intractable in the slate recommendation scenario. In that setting, an action corresponds to a slate that may contain any combination of items. In this work we propose to encode slates in a continuous, low-dimensional latent space learned by a variational auto-encoder. We are able to (i) relax assumptions required by previous work, and (ii) improve the quality of the action selection by modeling full slates.
