title: Nonnegative tensor decomposition example using Tensorly
body: <p>I am very new to <strong>tensor</strong> and also to <strong>tensorly</strong> Library.I come across one of the best examples of tensor decomposition on <a href="http://jeankossaifi.com/blog/rpca.html" rel="nofollow noreferrer">jeankossaifi</a> but I need an example of tensorly function non_negative_tucker() for tensor decomposition by extending the example on the link above (for Olivetti dataset).</p>
