The Pattern Search and Steepest Descent methods are the most robust, converging to the positive quadrant minimum in almost every starting point within the 10 by 10 quadrant. I have noted the conditions and shown plots for each of these methods that can make the method converge to a negative quadrant minimum.

Homework 3 Fall 2019 (Due: Nov. 1, 2019) Introduction This assignment is on deep neural network optimization, which is covered in Chapter 8 of the recommended text. Exercises 1.(Stochastic Gradient Descent - Minibatch Size) Describe the major factors that contribute to choice of the minibatch size for stochastic gradient descent.

Steepest descent is a gradient algorithm where the step size is chosen to achieve the maximum amount of decrease of the objective function at each individual step. At each step, starting from the point, we conduct a line search in the direction until a minimizer,, is found. Proposition 8.1 8 Proposition 8.1: If is a steepest descent sequence.The Method of Steepest Ascent is a means to design experiments to efficiently find such optimal conditions. If we were to plot all possible responses of the system of interest to an f number of factors, we would end up with an f-dimensional surface.Homework 6 for Numerical Optimization due February 9 ,2004(Convergence rate of the Steepest Descent algorithm ) Homework 7 for Numerical Optimization due February 13 ,2004( (Modified Newton method with Armijo line search).
