So, none of them may share a row, column, or diagonal with any other. In a previous post, I introduced Raymond Hettinger’s ‘Easy AI with…

# A Neural Network in Python, Part 2: activation functions, bias, SGD, etc.

This is Part 2 of A Neural Network in Python, which was a very simple neural network to learn the XOR function. This part builds on that example to demonstrate more activation functions, learning a simple math function, adding a bias, improvements to the initial random weights, stochastic gradient descent, mean square error loss function,…

# Easy AI with Python 3

Survey several basic AI techniques implemented with short, open-source Python code recipes. Appropriate for educators and programmers who want to experiment with AI and apply the recipes to their own problem domains. For each technique, learn the basic operating principle, discuss an approach using Python, and review a worked out-example. We’ll cover database mining using…
