If you have a question about this talk, please contact Prof Ian Kenyon.

The talk will start with an introduction to data visualisation for large dimensional data and the use of parallel coordinates. This motivates the use of information theoretic ideas to understand multivariate data and a new histogramming algorithm based on the Shannon entropy of the data which quantifies the meaning of the expressions “underbinned” and “overbinned”. A data driven approach is then used to answer key questions; how are the variables related: how many dimensions are needed to describe a dataset: what variables are key to a particular class of events and why this is relevant to data mining algorithms: and is there a fundamental limit to how two classes of events can be separated ?
