hi_class background evolution, initial conditions and approximation schemes [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
Cosmological datasets have great potential to elucidate the nature of dark energy and test gravity on the largest scales available to observation. Theoretical predictions can be computed with hi_class (www.hiclass-code.net), an accurate, fast and flexible code for linear cosmology, incorporating a wide range of dark energy theories and modifications to

A new iterative initialization of EM algorithm for Gaussian mixture models.

PLoS ONE, 2023
BackgroundThe expectation maximization (EM) algorithm is a common tool for estimating the parameters of Gaussian mixture models (GMM). However, it is highly sensitive to initial value and easily gets trapped in a local optimum.MethodTo address these ...
