Description
What is this course?
Decision Tree Model building is one of the most applied technique in analytics vertical. The decision tree model is quick to develop and easy to understand. The technique is simple to learn. A number of business scenarios in lending business / telecom / automobile etc. require decision tree model building.
This course ensures that student get understanding of
- what is the decision tree
- where do you apply decision tree
- what benefit it brings
- what are various algorithm behind decision tree
- what are the steps to develop decision tree in R
- how to interpret the decision tree output of R
