*Information to attend*
*In presence*: The seminar will take place in room 3014, at the building
U5-Ratio, Università degli Studi di Milano Bicocca.

*Title*: "Persistent Homology and Application to Music Classification"

*Abstract*: Persistent homology is a computational tool which was created
in the end of the 20th century for applied algebraic topology. The main
idea is to understand the topological structure of a starting object by
progressive approximations: for that we use simplicial theory and more
precisely simplicial complexes and homology, which we will begin by remind
the basis. In practice, we extract from our starting object a point cloud
and we change it into a filtered simplicial complex by using an algorithm
called the Vietoris-Rips filtration. Persistent homology then encodes the
evolution of homology classes and more precisely their lifespan in the new
created filtration. We will represent all these informations on a family of
graphs called barcodes, from which we will be able to analyze or even
compare several starting objects: this process is called Topological Data
Analysis. As an illustration of persistent homology and TDA, we will see
how we can apply it to classification of musical style.

*Keywords*: Persistent homology, simplicial theory, applied algebraic
topology, topological data analysis, barcodes, music classification.
