### #010 TF TensorBoard: Visualizing Learning

Highlights: In this post we will learn what is TensorBoard and how to use it. For most people, neural networks can sometimes be a bit of black box. Debugging problems is also a lot easier when we can see what the problem is. Thankfully, TensorBoard is a tool that will help us to analyze neural networks and to visualize learning. Tutorial Overview: Sequential API Model Subclassing Intro The idea of TensorBoard is to help to…

### #009 Activation functions and their derivatives

Activation functions When we build a neural network, one of the choices we have to make is what activation functions to use in the hidden layers as well as at the output unit of the  Neural Network. So far, we’ve just been using the sigmoid activation function but sometimes other choices can work much better.  Let’s take a look at some of the  options. $$sigmoid$$ activation function In the forward propagation steps for Neural Network there are two steps…
