ruby_linear_regression (rubygems): An implementation of a linear regression machine learning algorithm implemented in Ruby.   The library supports simple problems with one independent variable used to predict a dependent variable as well as multivariate problems with multiple independent variables to predict a dependent variable.   You can train your algorithms using the normal equation or gradient descent.   The library is implemented in pure ruby using Ruby's Matrix implementation.
