If Dante were a Data Scientist: Inferno & Data (part I)

What if Dante was not describing his redemption journey through Hell, Purgatory and Heaven, but he was poetically describing a Data Science journey through Data, Modelling and Deployment? The start of his first "Canto" in Inferno would have been written as… Midway upon my journey in the realm of data science, I found myself within a sea of algorithms and code, For the straightforward path of understanding had been lost. How hard a thing it is to say What was this chaos of machine learning models and techniques, Which in the very thought renews the confusion. So bitter is it, learning is little more; But of the good to treat, which there I found, Speak will I of the insights and discoveries I made there. Divina Commedia meets data science in this three-part series that explores the machine learning project lifecycle through the lens of Dante's epic journey through Hell, Purgatory, and Heaven.
