The most popular dataset on Kaggle is Credit Card Fraud Detection. It’s an easy to understand problem space and impacts just about everyone. Fraud detection is a practical application that many businesses care about. There’s a also something intrinsically cool about stopping crime with AI.
Here’s an interesting article on how to implement a fraud detection system with TensorFlow, PySpark, and Cortex.
While it would be cool to just build an accurate model, it would be more useful to build a production application that can automatically scale to handle more data, update when new data becomes available, and serve real-time predictions. This usually requires a lot of DevOps work, but we can do it with minimal effort using Cortex, an open source machine learning infrastructure platform. Cortex converts declarative configuration into scalable machine learning pipelines. In this guide, we’ll see how to use Cortex to build and deploy a fraud detection API using Kaggle’s dataset.
