Gradient descent is based on the observation that if the multi-variable function is defined and differentiable in a neighborhood of a point , then () decreases fastest if one goes from in the direction of the negative gradient of at , ().It follows that, if + = for a small enough step size or learning rate +, then (+).In other words, the term () is subtracted from because we want to move . So we can just basically do back substitution and solve and won't get one solution. Prove that if there is trail in a graph G from vertex to a vertex W, then there is also a trail from W to v.
