<p>I thought that machine learning is a niche on stackoverflow until I have checked just for fun the <a href="https://stackoverflow.com/questions/tagged/machine-learning">corresponding tag</a>. It is true that some questions are more programming related than others, but I cannot get rid of the feeling that there are a lot of experts-by-practice with a solid background to answer more "theoretical" questions.  </p>

<p>Since then I have already flagged two questions to make the SO-mods move them to our site in the hope of attracting more users from there:</p>

<ul>
<li><a href="https://stats.stackexchange.com/questions/19915/using-a-histogram-to-estimate-class-label-densities-in-a-tree-learner">using-a-histogram-to-estimate-class-label-densities-in-a-tree-learner</a></li>
<li><a href="https://stats.stackexchange.com/questions/19996/data-mining-classification-competition">data-mining-classification-competition</a></li>
</ul>

<p>But I wonder a) if this is a valid strategy and b) what else we can do to attract more machine learners. </p>

<p><strong>Edit:</strong> Redirection to metaoptimize. What a heresy !(<a href="https://stackoverflow.com/questions/8238687/relational-fisher-kernel-implementation">see for yourself</a>).</p>
