<p>This example constructs a pipeline that does dimensionality
reduction followed by prediction with a support vector
classifier. It demonstrates the use of <code class="docutils literal"><span class="pre">GridSearchCV</span></code> and
<code class="docutils literal"><span class="pre">Pipeline</span></code> to optimize over different classes of estimators in a
single CV run – unsupervised <code class="docutils literal"><span class="pre">PCA</span></code> and <code class="docutils literal"><span class="pre">NMF</span></code> dimensionality
reductions are compared to univariate feature selection during
the grid search.</p>
<p>Additionally, <code class="docutils literal"><span class="pre">Pipeline</span></code> can be instantiated with the <code class="docutils literal"><span class="pre">memory</span></code>
argument to memoize the transformers within the pipeline, avoiding to fit
again the same transformers over and over.</p>
<p>Note that the use of <code class="docutils literal"><span class="pre">memory</span></code> to enable caching becomes interesting when the
fitting of a transformer is costly.</p>

<p>The <code class="docutils literal"><span class="pre">PCA</span></code> fitting is only computed at the evaluation of the first
configuration of the <code class="docutils literal"><span class="pre">C</span></code> parameter of the <code class="docutils literal"><span class="pre">LinearSVC</span></code> classifier. The
other configurations of <code class="docutils literal"><span class="pre">C</span></code> will trigger the loading of the cached <code class="docutils literal"><span class="pre">PCA</span></code>
estimator data, leading to save processing time. Therefore, the use of
caching the pipeline using <code class="docutils literal"><span class="pre">memory</span></code> is highly beneficial when fitting
a transformer is costly.</p>
