<p>One of the major &quot;wow!&quot; moments in the <a target="_blank" rel="nofollow" href="http://blog.revolutionanalytics.com/2016/03/sql-server-2016-launch.html">keynote where SQL Server 2016 was first introduced</a> was a demo that automated the process classifying images of galaxies in a huge database of astronomical images. </p>

<p>The SQL Server Blog has since published a <a target="_blank" rel="nofollow" href="https://blogs.technet.microsoft.com/dataplatforminsider/2017/01/05/how-six-lines-of-code-sql-server-can-bring-deep-learning-to-any-app/">step-by-step tutorial on implementing the galaxy classifier in SQL Server</a> (and the code is also <a target="_blank" rel="nofollow" href="https://github.com/Microsoft/SQL-Server-R-Services-Samples/tree/master/Galaxies">available on GitHub</a>). This updated version of the demo uses the new <a target="_blank" rel="nofollow" href="https://msdn.microsoft.com/en-us/microsoft-r/microsoftml-introduction">MicrosoftML package</a> in Microsoft R Server 9, and specifically the <code>rxNeuralNet</code> function for deep neural networks. The tutorial recommends using the <a target="_blank" rel="nofollow" href="https://azure.microsoft.com/en-us/blog/azure-n-series-general-availability-on-december-1/">Azure NC</a> class of virtual machines, to take advantage of the GPU-accelerated capabilities of the function, and provides details on using the SQL Server interfaces to train the neural netowrk and run predictions (classifications) on the image database.
