arXiv:2606.14929v1 Announce Type: cross Abstract: Modern recommendation systems increasingly rely on dynamically routing diverse queries to multiple embedding models. Despite its practical significance, this problem remains poorly understood under realistic conditions like adversarial queries, bandit feedback, and limited observability of models. We formalize embedding model routing as an adversarial contextual linear bandit with low-rank experts, where contexts are queries, actions are items, and experts are the embedding models working on low-rank latent representation spaces. We first estab
The increasing complexity of AI recommendation systems and the need for more efficient resource allocation drives research into optimizing model routing, making this a timely advancement.
This research formalizes a critical challenge in scaling AI recommendation systems, offering a framework to improve performance and resource efficiency for companies heavily reliant on embedding models.
The development of robust and adaptable routing policies for embedding models will enhance the precision and efficiency of large-scale AI applications, particularly in recommendation and search.
