Hierarchical Contextual Manifold Alignment for Structuring Latent Representations in Large Language Models

no code implementations6 Feb 2025 Meiquan Dong, Haoran Liu, Yan Huang, Zixuan Feng, Jianhong Tang, Ruoxi Wang

The organization of latent token representations plays a crucial role in determining the stability, generalization, and contextual consistency of language models, yet conventional approaches to embedding refinement often rely on parameter modifications that introduce additional computational overhead.

Hiformer: Heterogeneous Feature Interactions Learning with Transformers for Recommender Systems

no code implementations10 Nov 2023 Huan Gui, Ruoxi Wang, Ke Yin, Long Jin, Maciej Kula, Taibai Xu, Lichan Hong, Ed H. Chi

We identify two key challenges for applying the vanilla Transformer architecture to web-scale recommender systems: (1) Transformer architecture fails to capture the heterogeneous feature interactions in the self-attention layer; (2) The serving latency of Transformer architecture might be too high to be deployed in web-scale recommender systems.
