+<p><a href="https://en.wikipedia.org/wiki/Feature_selection" target="_blank">Feature Selection</a> is the process of selecting a subset of relevant features for use in model construction. </p>
+<p>It is a useful technique to 1) improve prediction results by omitting redundant features, 2) to shorten training time, and 3) to know important features for prediction.</p>

-<p><a href="https://en.wikipedia.org/wiki/Feature_selection" target="_blank">Feature Selection</a> is the process of selecting a subset of relevant features for use in model construction. </p>
-<p>It is a useful technique to 1) improve prediction results by omitting redundant features, 2) to shorten training time, and 3) to know important features for prediction.</p>
-<p><em>Note: This feature is supported from Hivemall v0.5-rc.1 or later.</em></p>
