<p>As a mental model, it can be helpful to consider the scope of Stats.SE and AI.SE as two circles of a Venn diagram.</p>
<ul>
<li>Some topics, like <a href="https://stats.stackexchange.com/questions/tagged/sigma-algebra" class="post-tag" title="show questions tagged &#39;sigma-algebra&#39;" rel="tag">sigma-algebra</a> or statistical hypothesis tests, are only on-topic on Stats.SE.</li>
<li>Some topics, like <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> and <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>, are on-topic on <strong>both</strong> sites.</li>
<li>Some topics, like philosophical or social consequences of AI, are only on-topic on AI.SE.</li>
</ul>
<p>(And, of course, there are lots of topics that aren't on-topic on either site but are on-topic somewhere else, or no where else, on Stack Exchange.)</p>
<p>Therefore, <strong>it's best to ask questions about <em>non-statistical</em> AI on AI.SE.</strong> If any user is unsure where to post a question, you can ask about it on stats.meta.SE and we'll point you in the right direction.</p>
