Credit Card Fraud Detection

MacDown logo


This is a demo project to showcase the features of the Cloudera Data Science Workbench.

The data used in this project is from Kaggle

“The datasets contains transactions made by credit cards in September 2013 by european cardholders. This dataset presents transactions that occurred in two days, where we have 492 frauds out of 284,807 transactions.

The project consists of 5 parts:

  • Part 1: Importing Data
  • Part 2: Data Analysis and Visualization
  • Part 3: Model Training 3_train_modelpy
  • Part 4: Model Deployment
  • Part 5: Model Tuning

Note: The data needs to be copied to the cluster first as per the file in order for this project to work properly

1: Importing Data

The data is imported from the cluster and saved to a local dataframe.

2: Data Analysis and Visualization

Perform some basic data analysis and visualisation techniques to understand the data better.

3: Model Training

Train an ML Model to predict additional values.

4: Model Deployment

Deploy the trained model to CDSW to integrate with other internal systems.

5: Model Tuning

Adjust the model hyper parameter values using an experiment to optimise the model.

6: Model Monitoring via Jobs

Checks the current state of model performance via the Jobs interface

7: Model Monitoring via Experiments

Checks the current state of model performance via the Experiments interface

8: Model Retraining

Called to retrain the model if there the job in 6 finds the model is below threshold

Note: For the model deployment, use the following JSON as the example input:
