spectrally-regularised-lvms 0.1.3

A framework of linear LVMs with spectral regularisation.

Spectrally regularised LVMs

Spectrally-regularised-LVMs is a Python-based package which facilitates the estimation of the linear latent variable model (LVM) parameters with a unique spectral regularisation term in single channel time-series applications.

Purpose

LVMs are a statistical methodology which try to capture the underlying structure in some observed data. This package caters to single channel time-series applications and provides a methodology to estimate the LVM parameters. The model parameters are encouraged to capture non-duplicate information via a spectral regularisation term which penalises source duplication of the spectral information captured by the latent sources.

The purpose of this package is to provide a complete framework for LVMs with spectral regularisation that caters to a variety of LVM objective functions.
