Decoding in Latent Spaces for Efficient Inference in LLM-based Recommendation

EMNLP 2025

Fine-tuning large language models (LLMs) for recommendation in a generative manner has delivered promising results, but encounters significant inference overhead due to autoregressive decoding in the language space. This work explores bypassing language-space decoding by directly matching candidate

Diffusion Models are Good Unsupervised Class-agnostic Shape Part Segmentators

ICASSP 2025accepted

Shape part segmentation is a critical task in computer graphics and robotics. However, traditional supervised methods rely heavily on large amounts of labeled data, which poses significant challenges in many real-world scenarios where such data is often scarce or difficult to obtain. To address this…

Latent Inter-User Difference Modeling for LLM Personalization

EMNLP 2025

Large language models (LLMs) are increasingly integrated into users’ daily lives, leading to a growing demand for personalized outputs.Previous work focuses on leveraging a user’s own history, overlooking inter-user differences that are crucial for effective personalization.While recent work has att

SphereHead: Stable 3D Full-head Synthesis with Spherical Tri-plane Representation

ECCV 2024oral

"While recent advances in 3D-aware Generative Adversarial Networks (GANs) have aided the development of near-frontal view human face synthesis, the challenge of comprehensively synthesizing a full 3D head viewable from all angles still persists. Although PanoHead [?] proves the possibilities of usin…
