Decoding by Contrasting Knowledge: Enhancing Large Language Model Confidence on Edited Facts

ACL 2025long

The knowledge within large language models (LLMs) may become outdated quickly. While in-context editing (ICE) is currently the most effective method for knowledge editing (KE), it is constrained by the black-box modeling of LLMs and thus lacks interpretability. Our work aims to elucidate the superio…

LLMCBench: Benchmarking Large Language Model Compression for Efficient Deployment

NeurIPS 2024spotlight

Although large language models (LLMs) have demonstrated their strong intelligence ability, the high demand for computation and storage hinders their practical application. To this end, many model compression techniques are proposed to increase the efficiency of LLMs. However, current researches only…

Make Continual Learning Stronger via C-Flat

NeurIPS 2024poster

How to balance the learning ’sensitivity-stability’ upon new task training and memory preserving is critical in CL to resolve catastrophic forgetting. Improving model generalization ability within each learning phase is one solution to help CL learning overcome the gap in the joint knowledge space.…

Metric from Human: Zero-shot Monocular Metric Depth Estimation via Test-time Adaptation

NeurIPS 2024poster

Monocular depth estimation (MDE) is fundamental for deriving 3D scene structures from 2D images. While state-of-the-art monocular relative depth estimation (MRDE) excels in estimating relative depths for in-the-wild images, current monocular metric depth estimation (MMDE) approaches still face chall…

3D-Aware Neural Body Fitting for Occlusion Robust 3D Human Pose Estimation

ICCV 2023poster

Regression-based methods for 3D human pose estimation directly predict the 3D pose parameters from a 2D image using deep networks. While achieving state-of-the-art performance on standard benchmarks, their performance degrades under occlusion. In contrast, optimization-based methods fit a parametric…
