Extracting Human Attention through Crowdsourced Patch Labeling

no code implementations22 Mar 2024 Minsuk Chang, SeokHyeon Park, Hyeon Jeon, Aeri Cho, Soohyun Lee, Jinwook Seo

We demonstrated the effectiveness of our method in mitigating bias through improved classification accuracy and the refined focus of the model.

Classes are not Clusters: Improving Label-based Evaluation of Dimensionality Reduction

1 code implementation1 Aug 2023 Hyeon Jeon, Yun-Hsin Kuo, Michaël Aupetit, Kwan-Liu Ma, Jinwook Seo

In this paper, we introduce two novel quality measures -- Label-Trustworthiness and Label-Continuity (Label-T&C) -- advancing the process of DR evaluation based on class labels.

Sanity Check for External Clustering Validation Benchmarks using Internal Validation Measures

1 code implementation20 Sep 2022 Hyeon Jeon, Michael Aupetit, Donghwa Shin, Aeri Cho, SeokHyeon Park, Jinwook Seo

We then propose processes to generalize internal measures to fulfill these new axioms, and use them to extend the widely used Calinski-Harabasz index for between-dataset CLM evaluation.

Uniform Manifold Approximation with Two-phase Optimization

1 code implementation1 May 2022 Hyeon Jeon, Hyung-Kwon Ko, Soohyun Lee, Jaemin Jo, Jinwook Seo

We introduce Uniform Manifold Approximation with Two-phase Optimization (UMATO), a dimensionality reduction (DR) technique that improves UMAP to capture the global structure of high-dimensional data more accurately.

Distortion-Aware Brushing for Interactive Cluster Analysis in Multidimensional Projections

no code implementations17 Jan 2022 Hyeon Jeon, Michael Aupetit, Soohyun Lee, Hyung-Kwon Ko, Youngtaek Kim, Jinwook Seo

Brushing is an everyday interaction in 2D scatterplots, which allows users to select and filter data points within a continuous, enclosed region and conduct further analysis on the points.

Measuring and Explaining the Inter-Cluster Reliability of Multidimensional Projections

3 code implementations16 Jul 2021 Hyeon Jeon, Hyung-Kwon Ko, Jaemin Jo, Youngtaek Kim, Jinwook Seo

Our metrics consider two aspects of the inter-cluster reliability: Steadiness measures the extent to which clusters in the projected space form clusters in the original space, and Cohesiveness measures the opposite.

Interactive Visualization for Exploring Information Fragments in Software Repositories

no code implementations28 Apr 2021 Youngtaek Kim, Hyeon Jeon, Kiroong Choe, Hyunjoo Song, Bohyoung Kim, Jinwook Seo

Software developers explore and inspect software repository data to obtain detailed information archived in the development history.

Githru: Visual Analytics for Understanding Software Development History Through Git Metadata Analysis

2 code implementations7 Sep 2020 Youngtaek Kim, Jaeyoung Kim, Hyeon Jeon, Young-Ho Kim, Hyunjoo Song, Bohyoung Kim, Jinwook Seo

Furthermore, they do not scale for large and complex Git commit graphs, which can play an important role in understanding the overall development history.
