Speed-up the gaussian process regression #18

Open vbonvin opened 7 years ago

vbonvin commented 7 years ago

This paper proposes a new algorithm to speed-up the GPR computation: https://arxiv.org/pdf/1703.09710.pdf

And they have a python code that do that for us: http://celerite.readthedocs.io/en/latest/

I will try to implement that in PyCS and see how it compares to the current implementation, in terms of speed and efficiency

Cool! Interested to see how it performs, compared to the older curve shifting approach. It should provide an alternative (Bayesian) route to uncertainties on the time delays and magnifications too.
