Luis Scoccola (Northeastern)

PDL C401 and on Zoom
I will describe joint work with Jose Perea in which we propose combinatorial notions of vector bundle, study the extent to which these determine true vector bundles, and give algorithms for the stable and consistent computation of lowdimensional characteristic classes directly from these representations. I will also show how this framework can be used to frame a dimensionality reduction algorithm which preserves the global topology as well as the local linear structure of data.
This talk will be hybrid, held inperson and online on Zoom
