<p>We have no less than 13 tags containing "learning". Some of these are certainly fine, e.g. <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>, <a href="https://stats.stackexchange.com/questions/tagged/deep-learning" class="post-tag" title="show questions tagged &#39;deep-learning&#39;" rel="tag">deep-learning</a>, <a href="https://stats.stackexchange.com/questions/tagged/unsupervised-learning" class="post-tag" title="show questions tagged &#39;unsupervised-learning&#39;" rel="tag">unsupervised-learning</a>, <a href="https://stats.stackexchange.com/questions/tagged/supervised-learning" class="post-tag" title="show questions tagged &#39;supervised-learning&#39;" rel="tag">supervised-learning</a>, <a href="https://stats.stackexchange.com/questions/tagged/reinforcement-learning" class="post-tag" title="show questions tagged &#39;reinforcement-learning&#39;" rel="tag">reinforcement-learning</a>, <a href="https://stats.stackexchange.com/questions/tagged/manifold-learning" class="post-tag" title="show questions tagged &#39;manifold-learning&#39;" rel="tag">manifold-learning</a>, <a href="https://stats.stackexchange.com/questions/tagged/active-learning" class="post-tag" title="show questions tagged &#39;active-learning&#39;" rel="tag">active-learning</a> or <a href="https://stats.stackexchange.com/questions/tagged/multitask-learning" class="post-tag" title="show questions tagged &#39;multitask-learning&#39;" rel="tag">multitask-learning</a>. My issues are with the following one:</p>

<ul>
<li><p><a href="https://stats.stackexchange.com/questions/tagged/learning" class="post-tag" title="show questions tagged &#39;learning&#39;" rel="tag">learning</a> looks completely vacuous to me. Sometimes another of the *learning tags would be far better, and sometimes it seems to be used as a synonym for <a href="https://stats.stackexchange.com/questions/tagged/references" class="post-tag" title="show questions tagged &#39;references&#39;" rel="tag">references</a>. We currently have 63 questions tagged <a href="https://stats.stackexchange.com/questions/tagged/learning" class="post-tag" title="show questions tagged &#39;learning&#39;" rel="tag">learning</a>. I'm afraid that if we simply remove the tag, it will pop up again. Should it be burninated?</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>: the wiki excerpt says that "SL refers to the statistical perspective on machine learning." To be honest, I am less than convinced. Shouldn't <em>all</em> questions on CrossValidated that carry the <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> tag have at least some "statistical perspective"? Then again, the posters of 133 questions seem to disagree with me. Thoughts, anyone?</p></li>
<li><p><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> (25 questions), <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> (3 questions), <a href="https://stats.stackexchange.com/questions/tagged/representation-learning" class="post-tag" title="show questions tagged &#39;representation-learning&#39;" rel="tag">representation-learning</a> (3 questions): all these have no tag wiki. Can someone create one?</p></li>
</ul>
