Dimension reductions (DR) assist by organizing images in a 2D space based on similarities, but provide little support for explaining why images were placed together or apart in the 2D space. Additionally, they do not provide support for modifying and updating the 2D space to explore new relationships and organizations of images. To address these problems, we present an interactive DR method for images that uses visual features extracted by a deep neural network to project the images into 2D space and provides visual explanations of image features that contributed to the 2D location. In addition, it allows people to directly manipulate the 2D projection space to define alternative relationships and explore subsequent projections of the images. With an iterative cycle of semantic interaction and explainable-AI feedback, people can explore complex visual relationships in image data. Our approach to human-AI interaction integrates visual knowledge from both human mental models and pre-trained deep neural models to explore image data. We demonstrate our method through examples with collaborators in agricultural science. %B Advances in Visual Computing: 17th International Symposium, ISVC 2022, San Diego, CA, USA, October 3–5, 2022, Proceedings, Part I %I Springer-Verlag %C Berlin, Heidelberg %P 77–90 %@ 978-3-031-20712-9 %U https://doi.org/10.1007/978-3-031-20713-6_6 %R 10.1007/978-3-031-20713-6_6 %0 Conference Paper %B 2022 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC) %D 2022 %T Exploring Organization of Computational Notebook Cells in 2D Space %A Jesse Harden %A Christman, Elizabeth %A Nurit Kirshenbaum %A Wenskovitch, John %A Jason Leigh %A North, Chris %B 2022 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC) %P 1-6 %8 09/2022 %R 10.1109/VL/HCC53370.2022.9833128 %0 Journal Article %J IEEE Transactions on Visualization and Computer Graphics %D 2021 %T An Examination of Grouping and Spatial Organization Tasks for High-Dimensional Data Exploration %A Wenskovitch, John %A North, Chris %B IEEE Transactions on Visualization and Computer Graphics %V 27 %P 1742-1752 %8 1/2021 %N 2 %R 10.1109/TVCG.2020.3028890 %0 Conference Paper %B IEEE 6th Workshop on Everyday Virtual Reality (WEVR) %D 2020 %T Evaluating the Benefits of the Immersive Space to Think %A Lee Lisle %A Xiaoyu Chen %A Edward J.K.

Coordinated relationships can be formalized as biclusters. In order to support visual exploration of biclusters, bipartite graphs based visualizations have been proposed, and edge bundling is used to show biclusters. However, it suffers from edge crossings due to possible overlaps of biclusters, and lacks in-depth understanding of its impact on user exploring biclusters in bipartite graphs. To address these, we propose a novel bicluster-based seriation technique that can reduce edge crossings in bipartite graphs drawing and conducted a user experiment to study the effect of edge bundling and this proposed technique on visualizing biclusters in bipartite graphs. We found that they both had impact on reducing entity visits for users exploring biclusters, and edge bundles helped them find more justified answers. Moreover, we identified four key trade-offs that inform the design of future bicluster visualizations. The study results suggest that edge bundling is critical for exploring biclusters in bipartite graphs, which helps to reduce low-level perceptual problems and support high-level inferences. %B IEEE Transactions on Visualization and Computer Graphics %V 25 %P 2983-2998 %8 07/2019 %N 10 %R 10.1109/TVCG.2018.2861397 %0 Conference Paper %B EValuation of Interactive VisuAl Machine Learning systems, an IEEE VIS 2019 Workshop %D 2019 %T Evaluating Semantic Interaction on Word Embeddings via Simulation %A Yali Bian %A Michelle Dowling %A North, Chris %B EValuation of Interactive VisuAl Machine Learning systems, an IEEE VIS 2019 Workshop %8 10/2019 %0 Conference Paper %B 2018 IEEE Conference on Visual Analytics Science and Technology (VAST) %D 2018 %T The Effect of Semantic Interaction on Foraging in Text Analysis %A Wenskovitch, John %A Lauren Bradel %A Michelle Dowling %A House, Leanna %A North, Chris %X Completing text analysis tasks is a continuous sensemaking loop of foraging for information and incrementally synthesizing it into hypotheses. Past research has shown the advantages of using spatial workspaces as a means for synthesizing information through externalizing hypotheses and creating spatial schemas. However, spatializing the entirety of datasets becomes prohibitive as the number of documents available to the analysts grows, particularly when only a small subset are relevant to the task at hand. StarSPIRE is a visual analytics tool designed to explore collections of documents, leveraging users' semantic interactions to steer (1) a synthesis model that aids in document layout, and (2) a foraging model to automatically retrieve new relevant information. In contrast to traditional keyword search foraging (KSF), "semantic interaction foraging" (SIF) occurs as a result of the user's synthesis actions. To quantify the value of semantic interaction foraging, we use StarSPIRE to evaluate its utility for an intelligence analysis sensemaking task. Semantic interaction foraging accounted for 26% of useful documents found, and it also resulted in increased synthesis interactions and improved sensemaking task performance by users in comparison to only using keyword search. %B 2018 IEEE Conference on Visual Analytics Science and Technology (VAST) %0 Conference Paper %B VAST Challenge 2014 %D 2014 %T Event-Based Text Visual Analytics %A Wang, Ji %A Lauren Bradel %A North, Chris %K event extraction %K Semantic interaction %K sensemaking %K topic modelling %X We present an event-based approach for solving a directed sensemaking task in which we combine powerful information foraging tools with intuitive synthesis spaces to solve the VAST 2014 Mini-Challenge 1 (MC1). A combination of student-created and commericially available software are used to solve various aspects of the scenario. In addition to applying entitiy extraction and topic modelling, we enable the user to explore a large dataset using multi-model semantic interaction, which infers analytical reasoning from user actions to augment the data spatialization and determine what information should be presented and suggested to the user.
