I have a problem of a task using the formula of the Gradient Descent:
Perform two steps of the gradient descent towards a local minimum for the function given below, using a step size of 0.1 and an initial value of [1, 1]
I only get as result of the derivative 0.4x1, because x2 does not exist. Is this correct or should the result for the derivative be (0.4, 0)?
Note: Sorry, if my equation of the derivative is bad. I'm not a mathematician. Please, correct me, if my equation is absolutely wrong.
