emupy : Emulators in Python

Run Tests codecov

Version: 1.0.0

Code Repo : https://github.com/BayesLIM/emupy

About:

emupy is a generalized Python implementation of the emulator algorithm detailed in Kern et al. 2017, and includes methods for Principcal Component Analysis and Gaussian Process Regression. To see emupy applied specifically to emulating the 21cm EoR power spectrum, see pycape.

emupy version 1.0.0 has an updated API, and now also includes a generalized linear model emulator (emupy.linear.LinearEmulator) and a neural network emulator built on pytorch (emupy.nn.NNEmulator). emupy is only compatible with Python >= 3.6.
