How to build a decision tree model in IBM Db2

IBM Journey to AI blog

In this post, I will show how to develop, deploy, and use a decision tree model in a Db2 database. Using examples from the dataset, we’ll build a classification model with decision tree algorithm. I extract the hour part of these values to create, hopefully, better features for the learning algorithm.
