This video tutorial explains how to implement gradient descent from scratch using PyTorch's autograph feature. It covers setting up a simple model with random integer inputs, defining hyperparameters, and using squared error loss. The tutorial demonstrates computing gradients, updating parameters, and finalizing the model to achieve results close to the true parameter values.

What is the purpose of using the autograd feature in PyTorch?

• To manually calculate gradients

• To generate random numbers

• To automatically compute gradients

• To initialize model parameters

What is the equation used for generating the true values of Y in the model?

• Y = 2.5X + 10

• Y = 3.0X + 15

• Y = 1.8X + 32

• Y = 0.5X + 20

Why is it important to set 'requires_grad' to true for model parameters?

• To increase the learning rate

• To initialize parameters to zero

• To enable gradient calculation

• To prevent gradient calculation

What is the purpose of using 'torch.no_grad()' in the code?

• To compute gradients

• To increase the learning rate

• To initialize random numbers

• To perform mathematical operations without computing gradients

What were the final values of the parameters W and B after training?

• W = 1.0, B = 32

• W = 2.0, B = 35

• W = 1.7999, B = 31.995

• W = 1.5, B = 30
