More and more, the products of statistical analysis that we encounter in our everyday lives come in the form of data visualizations. Visualizations have the advantage of being easier to interpret for many people, but they also give the impression of being a form of absolute truth. As with any presentation method, though, visualizations can be manipulated by their creators to show the story they...

A new approach for data visualization problem

Data visualization is the process of transforming data, information, and knowledge into visual form, making use of humans’ natural visual capabilities which reveals relationships in data sets that are not evident from the raw data, by using mathematical techniques to reduce the number of dimensions in the data set while preserving the relevant inherent properties. In this paper, we formulated d...

(in alphabetic order by speaker surname) Speaker: Dominique Attali (CNRS, Grenoble) Title: Persistence-sensitive simplification of functions on surfaces in linear time. Abstract: Let f be a real-valued function defined on a triangulated surface S. The persistence diagram of f encodes the homological variations in the sequence of sublevel sets St = f−1(−∞, t]. A point (x, y) in the persistence d...
