Real-Time Machine Learning

Imagine this scenario: You have an app that uses machine learning and you want the app to learn from your user's data in real-time. That means as new user data is generated, your app is able to make predictions and perform training on the incoming data-stream to improve itself automatically. How would you go about building this? Take some time to stare at this chart, it's an example of this pipeline. That text data is being streamed in real-time using a software product called "Apache Kafka" to a model.
