Lost in Translation: When GPT-4V(ision) Can't See Eye to Eye with Text. A Vision-Language-Consistency Analysis of VLLMs and Beyond

no code implementations19 Oct 2023 Xiang Zhang, Senyu Li, Zijun Wu, Ning Shi

Expanding on our findings, we introduce "Vision Description Prompting," a method that effectively improves performance in challenging vision-related tasks.

Zero-Shot Continuous Prompt Transfer: Generalizing Task Semantics Across Language Models

1 code implementation2 Oct 2023 Zijun Wu, Yongkang Wu, Lili Mou

Prompt tuning in natural language processing (NLP) has become an increasingly popular method for adapting large language models to specific tasks.

Unsupervised Chunking with Hierarchical RNN

1 code implementation10 Sep 2023 Zijun Wu, Anup Anand Deshmukh, Yongkang Wu, Jimmy Lin, Lili Mou

Our approach involves a two-stage training process: pretraining with an unsupervised parser and finetuning on downstream NLP tasks.

A Data-Centric Solution to NonHomogeneous Dehazing via Vision Transformer

1 code implementation16 Apr 2023 Yangyi Liu, Huan Liu, Liangyan Li, Zijun Wu, Jun Chen

Although it is possible to augment the NH-HAZE23 dataset by leveraging other non-homogeneous dehazing datasets, we observe that it is necessary to design a proper data-preprocessing approach that reduces the distribution gaps between the target dataset and the augmented one.

New Benchmark for Household Garbage Image Recognition

no code implementations24 Feb 2022 Zhize Wu, Huanyi Li, XiaoFeng Wang, Zijun Wu, Le Zou, Lixiang Xu, Ming Tan

Household garbage images are usually faced with complex backgrounds, variable illuminations, diverse angles, and changeable shapes, which bring a great difficulty in garbage image classification.

Towards Multi-Domain Single Image Dehazing via Test-Time Training

no code implementations CVPR 2022 Huan Liu, Zijun Wu, Liangyan Li, Sadaf Salehkalaibar, Jun Chen, Keyan Wang

Motivated by this observation, we propose a test-time training method which leverages a helper network to assist the dehazing model in better adapting to a domain of interest.

Weakly Supervised Explainable Phrasal Reasoning with Neural Fuzzy Logic

1 code implementation18 Sep 2021 Zijun Wu, Zi Xuan Zhang, Atharva Naik, Zhijian Mei, Mauajama Firdaus, Lili Mou

In this work, we address the explainability of NLI by weakly supervised logical reasoning, and propose an Explainable Phrasal Reasoning (EPR) approach.

GridDehazeNet+: An Enhanced Multi-Scale Network with Intra-Task Knowledge Transfer for Single Image Dehazing

no code implementations25 Mar 2021 Xiaohong Liu, Zhihao Shi, Zijun Wu, Jun Chen

We also propose a novel intra-task knowledge transfer mechanism that can memorize and take advantage of synthetic domain knowledge to assist the learning process on the translated data.

An Improved Generic Bet-and-Run Strategy for Speeding Up Stochastic Local Search

no code implementations23 Jun 2018 Thomas Weise, Zijun Wu, Markus Wagner

We propose using more advanced methods to discriminate between "good" and "bad" sample runs, with the goal of increasing the correlation of the chosen run with the a-posteriori best one.

Stochastic Runtime Analysis of a Cross Entropy Algorithm for Traveling Salesman Problems

no code implementations21 Dec 2016 Zijun Wu, Rolf Moehring, Jianhui Lai

For simple instances that have a $\{1, n\}$-valued distance function and a unique optimal solution, we prove a stochastic runtime of $O(n^{6+\epsilon})$ with the vertex-based random solution generation, and a stochastic runtime of $O(n^{3+\epsilon}\ln n)$ with the edge-based random solution generation for an arbitrary $\epsilon\in (0, 1)$.
