In topological machine learning one tries to combine methods from both topological data analysis and machine learning for application to data analysis.

A popular approach (originating around RHBK15, KHNL15) is to use persistent homology as a pre-processing stage and train neural networks not on full data sets, but on their persistence diagram/barcode (which may still be a large amount of data), by making these amenable to kernel methods.


On feeding persistence diagrams into machine learning-algorithms by equipping them with kernels:
