James McCaffrey uses cross entropy error via Python to train a neural network model for predicting a species of iris flower. In this article, I explain cross entropy ...

So I got to work fairly quickly. Python was already installed on my Linux laptop. I added NumPy (think “numbers” and “Python” — a package for numerical/scientific computing in Python) plus ...

The data science doctor continues his exploration of techniques used to reduce the likelihood of model overfitting, caused by training a neural network for too many iterations. Regularization is a ...

“Don’t spend your time doing work a well-trained monkey could do. Even if you’ve never written a line of code, you can make your computer do the grunt work.” – Al Sweigart, author of Automate the ...
