Coding a Full Neural Network from Scratch in Python | Deep Learning
In this lecture, we build a Multi Layer Neural network in python with just numpy as our core dependency.
We start with a visual theory session where we visualize how a neural network works and introduce the idea of a layer in a neural network. Then we visually explore a couple of network architectures
Next, we start with a single neuron we have previously covered but with a tanh activation function.
Finally we manually connect neurons into Layers. Next we build the layers and finally assemble layers into a neural network. We run both the network through a forward and backward pass.
This series is taught by Dr Anil Variyar, who has a PhD in Aeronautics and Astronautics from Stanford University.
