CTR prediction model based on pure Spark MLlib, no third-party library.

• Naive Bayes
• Logistic Regression
• Factorization Machine
• Random Forest
• Gradient Boosted Decision Tree
• GBDT + LR
• Neural Network
• Inner Product Neural Network (IPNN)
• Outer Product Neural Network (OPNN)

It's a maven project. Spark version is 2.3.0. Scala version is 2.11.
After dependencies are imported by maven automatically, you can simple run the example function (com.ggstar.example.ModelSelection) to train all the CTR models and get the metrics comparison among all the models.
