</pre><p>We typically can achieve a final fit of f = 0.97. The method stops when the change in the fit becomes less than the specified tolerance, which defaults to 1-e4.</p><h2 id="4">Visualize the results</h2><p>Use the <tt>ktensor/viz</tt> function to visualize the results.</p><pre class="codeinput">vizopts = {<span class="string"
