Capturing Graphs with Hypo-Elliptic Diffusions
Csaba Toth, Darrick Lee, Celia Hacker +1
Convolutional layers within graph neural networks operate by aggregating information about local neighbourhood structures; one common way to encode such substructures is through ra…
A Topological Approach to Mapping Space Signatures
Chad Giusti, Darrick Lee, Vidit Nanda +1
A common approach for describing classes of functions and probability measures on a topological space is to construct a suitable map from into a vec…
Path Signatures on Lie Groups
Darrick Lee, Robert Ghrist
Path signatures are powerful nonparametric tools for time series analysis, shown to form a universal and characteristic feature map for Euclidean valued time series data. We lift t…
Iterated Integrals and Population Time Series Analysis
Chad Giusti, Darrick Lee
One of the core advantages topological methods for data analysis provide is that the language of (co)chains can be mapped onto the semantics of the data, providing a natural avenue…
