Visualizing Gradient Descent

#1

Regarding video “Visualizing Gradient Descent”
How 3 D plot between T0,T1,J is related with that theta used in GradientDescent function ??
How are we able to relate them ,I am not getting .plz help!!!

Hey,
T0 and T1 are the surfaces corresponding to the theta0 and theta1 and J is the error at any point of (theta0, theta1)
There 2 surfaces are x and y axis which are denoting the theta0 and 1 whereas at any point (theta0, theta1) the Z axis will give you the error (J) corresponding to this point.

Thanks :slight_smile:
