Getting started
===============
The key idea behind ReliefE is simplicity. The purpose of this library is to offer off-the-shelf
functionality not supported elsewhere, with minimal user effort.
The data used in the example is accessible at: https://github.com/SkBlaz/reliefe/tree/master/data

The minimal example is given next.

.. code:: python3

	  
	import reliefe
	import scipy.io as sio
	import numpy as np

	# Load the data first
	mat_obj = sio.loadmat("data/mcc/chess.mat")
	x = mat_obj['input_space'] ## scipy csr sparse matrix (or numpy dense)
	y = mat_obj['target_space']  ## scipy csr sparse matrix (or numpy dense)

	# Fully fledged ReliefE (with all functionality)
	reliefE_instance = reliefe.ReliefE() # Initialize default ReliefE
	reliefE_instance.fit(x, y) # Compute rankings
	print(reliefE_instance.feature_importances_) # rankings for features (same order as x)


Returns the following ranking:
