How Wrangling Tools Shape Wrangling: A Technical Dimensions Analysis
Shiyi He, El Kindi Rezig, Paul Rosen +1
Wrangling consumes a disproportionate share of the effort associated with any data project. While a variety of tools support it, relatively little is known about how their differin…
GASP: A Gradient-Aware Shortest Path Algorithm for Boundary-Confined Visualization of 2-Manifold Reeb Graphs
Sefat E. Rahman, Tushar M. Athawale, Paul Rosen
Reeb graphs are an important tool for abstracting and representing the topological structure of a function defined on a manifold. We have identified three properties for faithfully…
Buckaroo: A Direct Manipulation Visual Data Wrangler
Annabelle Warner, Andrew McNutt, Paul Rosen +1
Preparing datasets -- a critical phase known as data wrangling -- constitutes the dominant phase of data science development, consuming upwards of 80% of the total project time. Th…
ChannelExplorer: Exploring Class Separability Through Activation Channel Visualization
Md Rahat-uz- Zaman, Bei Wang, Paul Rosen
Deep neural networks (DNNs) achieve state-of-the-art performance in many vision tasks, yet understanding their internal behavior remains challenging, particularly how different lay…
