lsqfitgp

lsqfitgp

Python module to do inference with Gaussian processes. Features:

• Based on JAX.
• Interoperates with gvar and lsqfit to facilitate inexpert users.
• Recursively structured covariates.
• Apply arbitrary linear transformations to the processes, finite and infinite.
• Small PPL based on Gaussian copulas to specify the hyperparameters prior.
• Rich collection of covariance functions.
• Good GP versions of BART (Bayes Additive Regression Trees) and BCF (Bayesian Causal Forests).

See this report for the theory behind lsqfitgp.

Installation

Python >= 3.9 required. Then:

$ pip install lsqfitgp

Documentation

The complete manual is available online at gattocrucco.github.io/lsqfitgp/docs. All the code is documented with docstrings, so you can also use the Python help system directly from the shell:

>>> import lsqfitgp as lgp
>>> help(lgp)
>>> help(lgp.something)

or, in an IPython shell/Jupyter notebook/Spyder IDE, use the question mark shortcut:

In [1]: lgp?

In [2]: lgp.something?
