DESCRIPTION:Visualization research - from data analysis to science communication
URL;VALUE=URI:https://www.csa.iisc.ac.in/newweb/event/402/visualization-research-from-data-analysis-to-science-communication/
SUMMARY:Visualization is omnipresent in everyday life serving many different purposes, examples range from plots in the newspapers to illustrations in textbooks. However, visualization goes far beyond such examples and pretty pictures. Visual data analysis has developed into an essential component of modern scientific workflows supporting understanding and reasoning about data. In this talk, I will mainly focus on the use of visualization for data analysis and exploration, and conclude with an outlook on how similar methods can be used in science communication.

As data is increasingly large and complex, effective data exploration requires abstractions that serve as a backbone for easy navigation through data. To this end, topological data analysis (TDA) has proven to provide fundamental tools in visualzaiton applicaitons.  It provides multi-scale data summaries with nice mathematical properties and guarantees. In the talk, I will demonstrate a few examples using topological descriptors for feature tracking in time-dependent scalar fields.  The examples include cyclone evolutions in weather modeling and structure tracking in flow simulations.
