<p>The question "<a href="https://stats.stackexchange.com/questions/403741/what-is-sigma-function-in-the-yolo-object-detector">What is sigma function in the YOLO object detector?</a>" has been closed as off-topic with the usual explanation:</p>

<blockquote>
  <p>This question appears to be off-topic because EITHER it is not about statistics, machine learning, data analysis, data mining, or data visualization, OR it focuses on programming, debugging, or performing routine operations within a statistical computing platform. If the latter, you could try the support links we maintain.</p>
</blockquote>

<p>However, I think it does not really fit this description:</p>

<ul>
<li>It is arguably about machine learning.</li>
<li>It is not about debugging neither performing routine operations within a statistical platform.</li>
</ul>

<p>It clearly asks for explanation of mathematical notation used in one particular paper. It has even got two answers (one being accepted) before being closed. For the OP, it makes no difference whether it stays closed or not, but for any future visitors, it sends a message that "we don't want such questions here". In my opinion, it is not the case&mdash;except for using a screenshot instead of writing down the equations, it is an on-topic and answerable question.</p>

<p>Before I vote to reopen, I would like to know if I may have overlooked any other reason for off-topicness of this particular question.</p>
