February 2nd from 12:00 to 13:00 room 207 Viale Romania 32 00197 Roma Speaker Pierpaolo Brutti (Sapienza Università di Roma) Title A (bittersweet) topological data analysis aperitif Abstract In recent years the statistical analysis of topological signatures computable from a possibly high-dimensional point cloud has attracted increasing attention from a theoretical as well as applied point of view. In this talk I will informally review the basic techniques and main inferential results available in the TDA toolkit showing them in action (...with their pros-&-cons...) on two classification problems related to activity tracking tasks (joint with Tullia Padellini). ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/
