A Practical Series on Recommendation Systems

Today, I am announcing a series of posts I am developing about recommendation systems. The series is aimed at software/machine learning engineers. I have two goals for the series: Provide practical and implementable strategies for delivering recommendations in real-time Present the mathematical intuition behind recommender problems The reason for the first goal is that I… Read More A Practical Series on Recommendation Systems

Can you norm rows and standardize columns at the same time?

If you are reading this, you probably already know that data pre-processing is the 90% perspiration of machine learning. You might love it or you might dread it, but you probably don’t think of it as a the part of ML where the most interesting mathematics lives. Let me challenge that view a bit with… Read More Can you norm rows and standardize columns at the same time?
