Logistic Regression

Use Cross Entropy typically
Two problems
1. Weights will be driven to -inf and +inf the longer we train
2. Near the asymptotes, gradient is really small

Often do both regularization and early stopping to counteract overfitting

ROC curve - Choose the decision threshold based on decision criteria
AUC - Provides total measure of performance across all possible classification thresholds
