Topological Data Analysis for Machine Learning
The goal of this tutorial is to give an introduction to the nascent field of topological machine learning, with the express purpose of being accessible to all audiences. The tutorial will discuss stateofthe art algorithms and provide the audience with the necessary competences to apply such techniques to their own research problems.
Requirements
This tutorial targets machine leaning researchers of any background. It is helpful if you already have some some knowledge about concepts from undergraduate mathematics, such as vector spaces and groups. If not, do not worry—I will provide intuitive descriptions for all of them during the tutorial.
To make the most of this session, I would recommend the following things:
 Some way of taking notes; the slides will be available (see below), so you could also annotate them along the way.
 A laptop with either Linux or Mac OS X will be helpful in order to try out some of the packages for computing persistent homology. This is not a necessity, though.
Course materials

Lecture 1: Algebraic Topology
In which we discuss an introduction to computational topology, the utility of Betti numbers, simplicial homology (with examples) and simplicial complexes, as well as how to compute all of this manually. 
Lecture 2: Computational Topology
In which we discuss a multiscale variant of simplicial homology, viz. persistent homology, provide copious examples, and show that everything—once again—boils down to neat linear algebra calculations. 
Lecture 3: Topological Descriptors & How to Use Them
In which we take a look at the landscape of existing topological descriptors, present their respective properties, and provide some guidance about their usage. 
Lecture 4: Recent Advances in Topological Machine Learning
In which we discuss recent research in topologydriven graph classification, as well as how to successfully integrate topological features into modern neural network architectures.
