Data Science: Theories, Models, Algorithms, and Analytics
Sanjiv Ranjan Das
I developed these class notes for my Machine Learning with R course. It traces my evolution as a data scientist into redundancy, I expect I will be replaced by a machine soon! There is a lot of work remaining to be done on this, including adding many more citations, replacing figures, and making sure full attribution is provided for all referenced material. Please do not cite or distribute at this time. Several chapters remain to be added.

“The public is more familiar with bad design than good design. It is, in effect, conditioned to prefer bad design, because that is what it lives with. The new becomes threatening, the old reassuring.” – Paul Rand
“It seems that perfection is attained not when there is nothing left to add, but when there is nothing more to remove.” – Antoine de Saint-Exupery
“In God we trust, all others bring data.” – William Edwards Deming
