Generalization of CNNs on Relational Reasoning with Bar Charts

1 code implementation28 Feb 2025 Zhenxing Cui, Lu Chen, Yunhai Wang, Daniel Haehn, Yong Wang, Hanspeter Pfister

We then test the generalization performance of CNNs on a classic relational reasoning task: estimating bar length ratios in a bar chart, by progressively perturbing the standard visualizations.

ChartInsights: Evaluating Multimodal Large Language Models for Low-Level Chart Question Answering

no code implementations11 May 2024 Yifan Wu, Lutao Yan, Leixian Shen, Yunhai Wang, Nan Tang, Yuyu Luo

To further explore the limitations of MLLMs in low-level ChartQA, we conduct experiments that alter visual elements of charts (e. g., changing color schemes, adding image noise) to assess their impact on the task effectiveness.

Mystique: Deconstructing SVG Charts for Layout Reuse

no code implementations25 Jul 2023 Chen Chen, Bongshin Lee, Yunhai Wang, Yunjeong Chang, Zhicheng Liu

To facilitate the reuse of existing charts, previous research has examined how to obtain a semantic understanding of a chart by deconstructing its visual representation into reusable components, such as encodings.

An Intelligent Model for Solving Manpower Scheduling Problems

1 code implementation7 May 2021 Lingyu Zhang, Tianyu Liu, Yunhai Wang

In addition, to the numerical solution of the manpower scheduling problem, this paper also studies the algorithm for scheduling task list generation and the method of displaying scheduling results.

Implicit Multidimensional Projection of Local Subspaces

1 code implementation7 Sep 2020 Rongzheng Bian, Yumeng Xue, Liang Zhou, Jian Zhang, Baoquan Chen, Daniel Weiskopf, Yunhai Wang

We propose a visualization method to understand the effect of multidimensional projection on local subspaces, using implicit function differentiation.

Deep-Learning Inversion of Seismic Data

no code implementations23 Jan 2019 Shucai Li, Bin Liu, Yuxiao Ren, Yangkang Chen, Senlin Yang, Yunhai Wang, Peng Jiang

We propose a new method to tackle the mapping challenge from time-series data to spatial image in the field of seismic exploration, i. e., reconstructing the velocity model directly from seismic data by deep neural networks (DNNs).

Progressive Data Science: Potential and Challenges

no code implementations19 Dec 2018 Cagatay Turkay, Nicola Pezzotti, Carsten Binnig, Hendrik Strobelt, Barbara Hammer, Daniel A. Keim, Jean-Daniel Fekete, Themis Palpanas, Yunhai Wang, Florin Rusu

We discuss these challenges and outline first steps towards progressiveness, which, we argue, will ultimately help to significantly speed-up the overall data science process.

DifNet: Semantic Segmentation by Diffusion Networks

no code implementations NeurIPS 2018 Peng Jiang, Fanglin Gu, Yunhai Wang, Changhe Tu, Baoquan Chen

Deep Neural Networks (DNNs) have recently shown state of the art performance on semantic segmentation tasks, however, they still suffer from problems of poor boundary localization and spatial fragmented predictions.
