<li><p>The <a href="https://stats.stackexchange.com/questions/tagged/learning" class="post-tag" title="show questions tagged &#39;learning&#39;" rel="tag">learning</a> tag is in the process of being removed, see the answer in  <a href="https://stats.meta.stackexchange.com/questions/4485">Understanding the use of the [education] tag</a>.</p></li>
<li><p>I wrote wiki excerpts to <a href="https://stats.stackexchange.com/questions/tagged/q-learning" class="post-tag" title="show questions tagged &#39;q-learning&#39;" rel="tag">q-learning</a> and <a href="https://stats.stackexchange.com/questions/tagged/transfer-learning" class="post-tag" title="show questions tagged &#39;transfer-learning&#39;" rel="tag">transfer-learning</a>. The former is IMHO a valid &amp; useful tag, about the latter I am not sure as it only has 5 threads, but the concept seems clear enough so I'd say let it be.</p></li>
<li><p>I removed <code>[representation-learning]</code> from all threads as too vague and unspecific.</p></li>
<li><p><a href="https://stats.stackexchange.com/questions/tagged/statistical-learning" class="post-tag" title="show questions tagged &#39;statistical-learning&#39;" rel="tag">statistical-learning</a> should become a synonym of <a href="https://stats.stackexchange.com/questions/tagged/machine-learning" class="post-tag" title="show questions tagged &#39;machine-learning&#39;" rel="tag">machine-learning</a>, see also the discussion in the comments above where everybody agrees with that.</p>

<p><strong>Update:</strong> The synonym has been created, thanks to @Scortchi.
Case closed.</p></li>
