Abstract: This paper introduces a novel, non-deterministic method for embedding data in low-dimensional Euclidean space based on computing realizations of a Gaussian process depending on the geometry of the data. This type of embedding first appeared in (Adler et al, 2018) as a theoretical model for a generic manifold in high dimensions.
In particular, we take the covariance function of the Gaussian process to be the heat kernel, and computing the embedding amounts to sketching a …
