EcoTune: Token-Efficient Multi-Fidelity Hyperparameter Optimization for Large Language Model Inference

EMNLP 2025

Tuning inference hyperparameters, such as temperature and maximum output tokens, on downstream tasks can enhance inference performance. However, directly applying hyperparameter optimization to these hyperparameters is token-expensive. Multi-fidelity optimization improves HPO efficiency with low-fid

Co-Speech Gesture Video Generation via Motion-Decoupled Diffusion Model

CVPR 2024poster

Co-speech gestures if presented in the lively form of videos can achieve superior visual effects in human-machine interaction. While previous works mostly generate structural human skeletons resulting in the omission of appearance information we focus on the direct generation of audio-driven co-spee…

CANDY: Category-Kernelized Dynamic Convolution for Instance Segmentation

ICASSP 2023accepted

Instance segmentation has been dominated by the paradigm that predicts masks using local RoI features and simplicity frameworks based on global mask prediction. Despite the comparable performance between local-based and global-based approaches, the AP results of objects on different scales vary sign…

Self-Paced Partial Domain-Aware Learning for Face Anti-Spoofing

ICASSP 2023accepted

With the widespread deployment of face authentication systems, domain generalization (DG) based face anti-spoofing (FAS) security approaches have drawn growing attention. Existing generalization-based methods always attempt to extract domain-invariant task information from data and eliminate domain-…
