Delinquency TELECOM MODEL

What is Delinquency telecom model ?

Delinquency is a condition that arises when an activity or situation does not occur at its scheduled (or expected) date i.e., it occurs later than expected.

In this project we have data of 190001 users of  a telecom company, the data includes information such as.

1. for how may years user is using the network.

2. how many times he takes loan in 3 months.

3. average amount he pays back in 3 months.

4. and will he be able to pay the loan in time or not.

This is a classification problem.

Libraries used in this project are

  • Pandas.
  • Sci-kit Learn.

Data split techniques used is K-FOLD with 10 folds

  • Accuracy model used is confusion metrics.

MODEL SELECTION AND ACCURACY EVALUATION

USING K FOLD

The data is split into 10 subsets and accuracy is evaluated.

1. logistic regression.

Accuracy 87 %.

2. Decision trees.

Accuracy  90%

SVM Using 20% of Training Data

Model training time 10 minutes.

For 50% of data it take more than two hours.

Accuracy of model 88% for 20% of test data.
