There is a talk coming up on Monday featuring one of the world’s leading thinkers about the mathematical structure of data. I highly encourage checking this out, as the talk should be aimed at a general audience (though with some serious math sprinkled in).

**The Shape of Data**

The problem of extracting knowledge and understanding from large and complex data sets is one of the fundamental intellectual challenges for the mathematical sciences. One approach to this is to use the notion of the “shape” of a data set, as encoded by a metric, as an organizing principle for data. Since topology is the mathematical discipline which concerns itself with the study of shape, it is only natural that methods from topology should be ported into the study of data. This transfer has in fact been taking place over the last 10-15 years, and we will discuss some of the ideas which have come up, with examples.
