HypRQ-VAE uses hyperbolic space for better long-tail recommendations

Researchers have introduced HypRQ-VAE, a novel framework for generative recommender systems that utilizes hyperbolic space to address the long-tail distribution of item catalogs. Unlike previous methods that operate in Euclidean space and struggle with sparse, niche preferences, HypRQ-VAE leverages the geometric properties of hyperbolic space to better model item hierarchies and sparsity. Experiments on benchmark datasets demonstrate that HypRQ-VAE significantly enhances recommendation performance, particularly for tail items, by preserving the representational fidelity of less popular items while incorporating rich textual semantics.

    HypRQ-VAE: Hyperbolic Item Indexing for Long-Tail-Aware Generative Recommender Systems

    Sequential recommender systems model user behavior as item ID sequences, while recent generative methods cast recommendation as a language modeling task using large language models (LLMs). While this paradigm incorporates rich textual semantics, it introduces a fundamental mismat…
