Building Machine Learning Systems with Python - Third Edition

Introduction to NumPy, SciPy, Matplotlib, and TensorFlow

Before we can talk about concrete machine learning algorithms, we have to talk about how best to store the data we will chew through. This is important as the most advanced learning algorithm will not be of any help to us if it will never finish. This may be simply because the mere process of accessing the data is too slow, or maybe its representation forces the operating system to swap all day. Add to this the fact that Python is an interpreted language (a highly optimized one, though) that is slow for many numerically heavy algorithms compared to C or Fortran. So we might ask why on earth so many scientists and companies are betting their fortune on Python even in highly computation-intensive ...
