Free online book - Machine Learning from Scratch

Hi all,

I'm writing to share a book I just published that I think many of you might find interesting or useful.

It provides complete derivations of the most common algorithms in ML (OLS, logistic regression, naive Bayes, trees, boosting, neural nets, etc.) both in theory and math. It also demonstrates constructions of each of these methods from scratch in Python using only numpy.



My aim with the…

How Big Data Analytics Certifications Aid Data Analysts

Students of technology, business, economics, mathematics, computer science, and the related subject domains, are all eligible to prepare for a data analyst role.

In the U.S., it is expected that there will exist 2.7 million openings…
