<p>Adaboost is an early example for a boosting algorithm. Does that make the <a href="https://stats.stackexchange.com/questions/tagged/adaboost" class="post-tag" title="show questions tagged &#39;adaboost&#39;" rel="tag">adaboost</a> tag a candidate for a tag synonym with <a href="https://stats.stackexchange.com/questions/tagged/boosting" class="post-tag" title="show questions tagged &#39;boosting&#39;" rel="tag">boosting</a>? Or is the policy that special cases can get their own tag? </p>

<p>If so, is there such a thing as a threshold? It seems obvious that there is a <a href="https://stats.stackexchange.com/questions/tagged/normal-distribution" class="post-tag" title="show questions tagged &#39;normal-distribution&#39;" rel="tag">normal-distribution</a> tag although there is a <a href="https://stats.stackexchange.com/questions/tagged/distributions" class="post-tag" title="show questions tagged &#39;distributions&#39;" rel="tag">distributions</a> tag, of which the former is a special case, so to speak. I would find it bizarre if, for example, someone came up with a <code>standard normal-distribution</code> tag on top, though.</p>
