Description

Anyone here familiar with the methods used here? It gives a linear-time exact solution for special case of one-dimensional data with covariance given by mixtures of exponentials.

The main implementation is celerite. There a full-Julia version by @ericagol here, and an alternate Julia implementation @dfm wrote to walk me through the basic ideas here.

Just thought I'd mention this, since it seems relevant if AbstractGPs is intended as a best-of-everything GP package (which... is that the case?)

Research direction

Start by reading the linked paper and comparing the Julia implementations in celerite.jl and Celerite2.jl. Then review AbstractGPs.jl's stated scope and existing Gaussian-process methods to determine whether this belongs in the package. Done means an agreed scope and implementation plan, not merely adding a method from the discussion.
