WaDi: Weight Direction-aware Distillation for One-step Image Synthesis

CVPR 2026

Despite the impressive performance of diffusion models such as Stable Diffusion (SD) in image generation, their slow inference limits practical deployment. Recent works accelerate inference by distilling multi-step diffusion into one-step generators. To better understand the distillation mechanism,

Effective Trajectory Generation for Robots on General 3D Curved Surface

RA-L 2024

More and more robots are required to adsorb or crawl on the 3D curved surface in order to assist humans in some dangerous or tedious tasks. Existing methods on curved surface are merely able to plan in 2.5D environment at best, limiting the applications of the robots. In this letter, we propose an e

On Large Language Models’ Hallucination with Regard to Known Facts

NAACL 2024long

Large language models are successful in answering factoid questions but are also prone to hallucination.We investigate the phenomenon of LLMs possessing correct answer knowledge yet still hallucinating from the perspective of inference dynamics, an area not previously covered in studies on hallucina…

Spontaneous gestures encoded by hand positions improve language models: An Information-Theoretic motivated study

ACL 2023findings

The multi-modality nature of human communication has been utilized to enhance the performance of language modeling-related tasks. Driven by the development of large-scale end-to-end learning techniques and the availability of multi-modal data, it becomes possible to represent non-verbal communicatio…

Gestures Are Used Rationally: Information Theoretic Evidence from Neural Sequential Models

COLING 2022main

Verbal communication is companied by rich non-verbal signals. The usage of gestures, poses, and facial expressions facilitates the information transmission in verbal channel. However, few computational studies have explored the non-verbal channels with finer theoretical lens. We extract gesture repr…

Rover Relocalization for Mars Sample Return by Virtual Template Synthesis and Matching

RA-L 2021

We consider the problem of rover relocalization in the context of the notional Mars Sample Return campaign. In this campaign, a rover (R1) needs to be capable of autonomously navigating and localizing itself within an area of approximately 50 ×50 m using reference images collected years earlier by a

BML: A High-performance, Low-cost Gradient Synchronization Algorithm for DML Training

NeurIPS 2018poster

In distributed machine learning (DML), the network performance between machines significantly impacts the speed of iterative training. In this paper we propose BML, a new gradient synchronization algorithm with higher network performance and lower network cost than the current practice. BML runs on…
