This is why you should visualize your data!

In the data science and data mining communities, several practitioners are applying various algorithms on data, without attempting to visualize the data.  This is a big mistake because sometimes, visualizing the data greatly helps to understand the data. Some phenomena are obvious when visualizing the data. In this blog post, I will give a few … Continue reading
