PrompTHis: Visualizing the Process and Influence of Prompt Editing during Text-to-Image Creation (2024)
Journal Article
Guo, Y., Shao, H., Liu, C., Xu, K., & Yuan, X. (2024). PrompTHis: Visualizing the Process and Influence of Prompt Editing during Text-to-Image Creation. IEEE Transactions on Visualization and Computer Graphics, https://doi.org/10.1109/TVCG.2024.3408255

Generative text-to-image models, which allow users to create appealing images through a text prompt, have seen a dramatic increase in popularity in recent years. However, most users have a limited understanding of how such models work and often rely...

Visual Analytics of Contact Tracing Policy Simulations During an Emergency Response (2022)
Journal Article
Sondag, M., Turkay, C., Xu, K., Matthews, L., Mohr, S., & Archambault, D. (2022). Visual Analytics of Contact Tracing Policy Simulations During an Emergency Response. Computer Graphics Forum, 41(3), 29-41. https://doi.org/10.1111/cgf.14520

Epidemiologists use individual-based models to (a) simulate disease spread over dynamic contact networks and (b) to investigate strategies to control the outbreak. These model simulations generate complex ‘infection maps’ of time-varying transmission... Read More about Visual Analytics of Contact Tracing Policy Simulations During an Emergency Response.
