Deep Learning - Deep Neural Network for Beginners Using Python - Sigma Prime

The video tutorial covers the implementation of a neural network, focusing on feedforward and backpropagation processes. It explains how to calculate derivatives within the network, using a simplified model with weights and biases. The tutorial introduces vectorized programming to efficiently compute derivatives and highlights the derivative of the sigmoid function, known as Sigma prime, which will be used in future lessons.

What is the significance of the bias in the calculation of H?

How can we calculate the value of H in a neural network?

Explain the process of calculating the partial derivative of H with respect to H1.

What is vectorized programming and how does it apply to calculating derivatives in neural networks?

Describe the derivative of the sigmoid function and its importance in neural networks.
