Course 312. Build a Neural Network Framework is rapidly nearlng completion. It's now over 1/3 complete, and extends up through writing the forward-propagation pass of a fully connected multi-layer network.
It's still available at the early order price of 6 USD. The full purchase price of 9 USD will go into effect on September 10. (The rest of the world doesn't know this, but I wanted to give you advance notice.)
