those B points so B is the size of your batch in this case now since B is normally not that large like I said maybe on the order of tens to a hundreds this is much faster to compute than full gradient descent and much more accurate than stochastic gradient descent because it's using more than one point more than one estimate now this increase in gradient accuracy estimation actually allows us to converge to our target much quicker because it means that our gradients are more accurate in practice it also means that we can increase our
