Overfitting, Regularization, and Hyperparameters – Subjective functions(This lays the ground work for the next post, which was getting too long to be effective.) Overfitting One of the goals of machine learning is generalizability. A model that only works on the exact data it was trained on is effectively useless. Let’s say you’re tasked with creating a bird-recognition system. If you train a model to recognize pictures of birds, and it gets 100% accuracy on the 130
