AutoGP.jl

This package contains the Julia reference implementation of AutoGP, a method for automatically discovering Gaussian process models of univariate time series data, as described in

Sequential Monte Carlo Learning for Time Series Structure Discovery.<br/> Saad, F A; Patton, B J; Hoffmann, M D.; Saurous, R A; Mansinghka, V K.<br/> ICML 2023: Proc. The 40th International Conference on Machine Learning.<br/> Proceedings of Machine Learning Research vol. 202, pages 29473-29489, 2023.

Whereas traditional Gaussian process software packages focus on inferring the numeric parameters for a fixed (user-specified) covariance kernel function, AutoGP learns both covariance kernel functions and numeric parameters for a given dataset. The plots below show two examples of online time series structure discovery using AutoGP, which discovers periodic components, trends, and smoothly-varying temporal components.

Installing

AutoGP can be installed using the Julia package manager. From the Julia REPL (version 1.8+), type ] to enter the Pkg REPL mode and run

pkg> add AutoGP

Alternatively, use the terminal command julia -e 'import Pkg; Pkg.add("AutoGP")'.
