Gradient Descent

#1

I can not understand why we use gradient descent instead of simply finding the point where slope is 0 . Since we are also using tangent in gradient descent formula

hey @garggaurav823,

Nothing can’t be perfect.
So , we want our model to be close to that point.

its not necessary that slope needs to come out 0 always.
we just want to get at the point , where it comes the minimum.
now that minimum can be 0, but not always and mostly not too.

Hence , we use gradient descent to get close to the minimum.
