<p>I wrote the following wiki excerpt:</p>

<blockquote>
  <p>Stochastic gradient descent (SGD) is a variant of gradient descent where only a small subset ("mini-batch") of training examples is used to compute the gradient on each iteration.</p>
</blockquote>

<p>Feel free to improve.</p>

<hr>

<p>It might make sense to create a synonym <code>[stochastic-gradient-descent]</code>$\to$<a href="https://stats.stackexchange.com/questions/tagged/sgd" class="post-tag" title="show questions tagged &#39;sgd&#39;" rel="tag">sgd</a>.</p>

<p><strong>Update: done.</strong></p>
