Reply to comment by make3333 in [D] Is there an advantage in learning when taking the average Gradient compared to the Gradient of just one point by CPOOCPOS
>gradient descent takes the direction of the minimum at the step size according to the taylor series of degree n at that point.
No. Gradient descent is first order by definition.
>in a lot of other optimization settings they do second order approx to find the optimal direction
It still isn't an "optimal" direction.

It is optimal in first order :)

Exactly, that is a meaningless phrase.
