An inexact Bregman proximal point method and its acceleration version for unbalanced optimal transport

no code implementations26 Feb 2024 Xiang Chen, Faqiang Wang, Jun Liu, Li Cui

The algorithm (1) converges to the true solution of UOT, (2) has theoretical guarantees and robust regularization parameter selection, (3) mitigates numerical stability issues, and (4) can achieve comparable computational complexity to the Scaling algorithm in specific practice.

Event-Based Visual Odometry on Non-Holonomic Ground Vehicles

1 code implementation17 Jan 2024 Wanting Xu, Si'ao Zhang, Li Cui, Xin Peng, Laurent Kneip

Despite the promise of superior performance under challenging conditions, event-based motion estimation remains a hard problem owing to the difficulty of extracting and tracking stable features from event streams.

Refining Sample Embeddings with Relation Prototypes to Enhance Continual Relation Extraction

1 code implementation ACL 2021 Li Cui, Deqing Yang, Jiaxin Yu, Chengwei Hu, Jiayang Cheng, Jingjie Yi, Yanghua Xiao

As a typical task of continual learning, continual relation extraction (CRE) aims to extract relations between entities from texts, where the samples of different relations are delivered into the model continuously.

Background Learnable Cascade for Zero-Shot Object Detection

1 code implementation9 Oct 2020 Ye Zheng, Ruoran Huang, Chuanqi Han, Xi Huang, Li Cui

The major contributions for BLC are as follows: (i) we propose a multi-stage cascade structure named Cascade Semantic R-CNN to progressively refine the alignment between visual and semantic of ZSD; (ii) we develop the semantic information flow structure and directly add it between each stage in Cascade Semantic RCNN to further improve the semantic feature learning; (iii) we propose the background learnable region proposal network (BLRPN) to learn an appropriate word vector for background class and use this learned vector in Cascade Semantic R CNN, this design makes \Background Learnable" and reduces the confusion between background and unseen classes.

A Geometric View of Optimal Transportation and Generative Model

no code implementations16 Oct 2017 Na Lei, Kehua Su, Li Cui, Shing-Tung Yau, David Xianfeng Gu

In this work, we show the intrinsic relations between optimal transportation and convex geometry, especially the variational approach to solve Alexandrov problem: constructing a convex polytope with prescribed face normals and volumes.
