What is grad[0] and grad[1]? Are they Q0 and Q1?
What is grad[0] and grad[1]
Hi @Anuvrat99
We initialize our gradient vector grad by using grad = np.zeros((2,)). This creates a row vector that contains two values [0.,0.] both are zero.
The grad[0] and grad[1] are used to access the first and second values of the row vector grad.
We are creating grad to store the updated gradient value.
Hope this might helps
