3. Result Iteration F(X) Jensen’s Approximation • 1: -3.718251e+003 -3.743897e+003 • 2: -3.743897e+003 -3.748634e+003 • 3: -3.748634e+003 -3.749596e+003 • 4: -3.749596e+003 -3.749788e+003

4. Result II

5. Current Approach • Pick gradient surface with the smallest L2 norms in Euclidean Space.

6. New Approach • Cluster Similar Gradient Surfaces • Jensen’s approximation cost function with Mixture of Gaussians and EM algorithms.
