<p>Consider these three questions (in chronological order):</p>

<ol>
<li><a href="https://stats.stackexchange.com/questions/133067">What exactly is a hyperparameter?</a></li>
<li><a href="https://stats.stackexchange.com/questions/149098">What do we mean by hyperparameters?</a></li>
<li><a href="https://stats.stackexchange.com/questions/208225">What&#39;s in a name: hyperparameters</a></li>
</ol>

<p>I think it's pretty clear that they are exact duplicates (currently only #2 is closed as a dup of #1). However, all three contain excellent answers. <strong>I would therefore suggest to merge all three questions into one of them.</strong></p>

<p>I think the best candidate for the "master thread" is #3, because it has most answers,  most upvotes, and most views, despite being the newest.</p>

<p>I flagged these threads for mod attention, but as per @Glen_b's suggestion I post this on meta too so that everybody could take a look and vote. Please upvote the question iff you agree that merging is a good idea.</p>
