description         Stochastic Gradient Descent
long_description    The goal of this package is to illustrate the efficiency of \
                    stochastic gradient descent for large-scale learning tasks. \
                    Two algorithms, Stochastic Gradient Descent (SGD), and \
                    Averaged Stochastic Gradient Descent (ASGD), are applied to \
                    two well known problems, Linear Support Vector Machines, and \
                    Conditional Random Fields.
