Exercises

  1. In the logistic regression-based click-through prediction project, can you also tweak hyperparameters such as penaltyeta0, and alpha in the SGDClassifier model? What is the highest testing AUC you are able to achieve?
  2. Can you try to use more training samples, for instance, 10 million samples, in the online learning solution?
  3. In the TensorFlow-based solution, can you tweak the learning rate, the number of training steps, and other hyperparameters to obtain a better performance?
