Machine learning a regularization approach pdf. Regularization Regularizationrefers to the act of modifying a learning algorithm to favor simpler prediction rules to avoid overfitting. Graesser July 31 2016 Research into regularization techniques is motivated by the tendency of neural networks to to learn the speci cs of the dataset it was trained on rather than learning general features that are applicable to unseen data. Specifically penalize weights that are large.

Most commonly regularization refers to modifying the loss function to penalizecertain values of the weights you are learning. I had been studying and actively researching in the. In the context of machine learning consistency is less immediately critical than generalization.
