Diffusion maps for changing data
Abstract:- Recently there has been a large class of research that utilizes
nonlinear mappings into low dimensional spaces in order to organize potentially
high dimensional data. Examples include, but are not limited to, locally linear
embedding (LLE), ISOMAP, Hessian LLE, Laplacian eigenmaps, and diffusion maps.
In this talk we will focus on the latter, and in particular consider how to
generalize diffusion maps to the setting in which we are given a data set that
evolves over time or changes depending on some set of parameters. Along with
describing the current theory, various synthetic and real world examples will
be presented to illustrate these ideas in practice. [video]
