scikit-tensor 0.1

Python module for multilinear algebra and tensor factorizations

scikit-tensor is a Python module for multilinear algebra and tensor factorizations.

Dependencies

The required dependencies to build the software are Numpy >= 1.3, SciPy >= 0.7.

Usage

Example script to decompose sensory bread data (available from http://www.models.life.ku.dk/datasets) using CP-ALS

import logging
from scipy.io.matlab import loadmat
from sktensor import dtensor, cp_als

# Set logging to DEBUG to see CP-ALS information
logging.basicConfig(level=logging.DEBUG)

# Load Matlab data and convert it to dense tensor format
mat = loadmat('../data/sensory-bread/brod.mat')
T = dtensor(mat['X'])

# Decompose tensor using CP-ALS
P, fit, itr, exectimes = cp_als(T, 3, init='random')
