Today, just as in the past, the “data” is invaluable and what we will try to do here is use simple data we can easily collect (data which individually might have no value) and apply Machine Learning techniques in order to identify anomalies, and then…

Understand Data If You Want to Visualize Data

Have you ever thought that the New York Times on an average Sunday contains more information than a Renaissance-era person had access to in his entire lifetime?
