Challenge 24 - Churning Problem Part 2 - Solution

0 ×

Just like in last week’s challenge, a telecom company wants you to predict which customers are going to churn (that is, going to cancel their contracts) based on attributes of their accounts. One of your colleagues said that she was able to achieve a bit over 95% accuracy for the test data without modifying the training data at all, and using all given attributes exactly as they are. Again, the target class to be predicted is Churn (value 0 corresponds to customers that do not churn, and 1 corresponds to those who do). What model should you train over the training dataset to obtain this accuracy over the test dataset? Can this decision be automated? Note 1: A simple, automated solution to this challenge consists of 5 nodes. Note 2: In this challenge, do not change the statistical distribution of any attribute or class in the datasets, and use all available attributes. Note 3: Need more help to understand the problem?
