robustica 0.1.2

Fully cumstomizable robust Independent Components Analysis (ICA)

robustica

Fully customizable robust Independent Component Analysis (ICA).

Description

This package contains 3 modules:

• RobustICA

  Defines the most important class that allows to perform and customize robust independent component analysis.

• InferComponents

  Retrieves the number of components that explain a user-defined percentage of variance.

• examples

  Contains handy functions to quickly create or access example datasets.

A more user-friendly documentation can be found at https://crg-cnag.github.io/robustica/.

Requirements

In brackets, versions of packages used to revelop robustica.

• numpy (1.19.2)
• pandas (1.1.2)
• scipy (1.6.2)
• scikit-learn (0.23.2)
• scikit-learn-extra (0.2.0)
• joblib (1.0.1)
• tqdm (4.59.0)

Installation

pip

pip install robustica

local

git clone https://github.com/MiqG/robustica.git
cd robustica
pip install -e .

Usage

from robustica import RobustICA
from robustica.examples import make_sampledata

X = make_sampledata(ncol=300, nrow=2000, seed=123)

rica = RobustICA(n_components=10)
S, A = rica.fit_transform(X)
