Stochastic gradient descent is a popular algorithm for training a wide range of models in machine learning, including (linear) support vector machines, logistic regression (see, e.g., Vowpal Wabbit) and graphical models. When combined with the backpropagation algorithm, it is the de facto standard algorithm for training artificial neural networks. Nonlinear Optimization: Algorithms and Models Robert J.

I have recently become very interested in the area of genetic algorithms and Ant Colony Optimization techniques. I was determined to write a complete program demonstrating these two techniques. In particular I wanted to compare the efficiency of these two approaches in the area of finding solutions to the Traveling Salesman Problem (TSP). presents our distributed algorithm for solving a convex optimization problem in the class, under the assumption that certain parameters of the problem instance are known to the algorithm. An analysis of the convergence rate of the algorithm appears in Section 4. Section 5 describes how to set and efficiently search for the necessary parameter ...
