optimization for machine learning jason brownlee pdf github

Regularization methods are also called penalization methods that introduce additional constraints into the optimization of a predictive algorithm such as a regression algorithm that bias the model toward lower complexity fewer coefficients. They are popular because people can achieve state-of-the-art results on challenging computer vision and natural language processing tasks.
