Title: Diffusion Maps, Spectral Clustering and Reaction Coordinates of
Dynamical Systems
Abstract:
A central problem in data analysis is the low dimensional representation
of high dimensional data, and the concise description of its underlying
geometry and density. In the analysis of large scale simulations of
complex dynamical systems, where the notion of time evolution comes into
play, important problems are the identification of the slow variables
and the representation of the reaction coordinates that parameterize
them.

In this paper we provide a unifying view of these apparently different
tasks, by considering a family of diffusion maps, defined as the
embedding of complex data onto a low dimensional Euclidian space, via
the eigenvectors of suitably normalized random walks defined on the
given datasets. We show, both theoretically and by examples how this
embedding can be used for dimensionality reduction, manifold learning,
geometric analysis of complex data sets and fast simulations of
stochastic dynamical systems. Joint work with R.R. Coifman, S. Lafon, M.
Maggioni and I.G. Kevrekidis
