Workshop: AI as an API (W026)
**The full course, including hands-on instructions, is on DataStax Academy. There, you will learn how to work in the Interactive Lab**.
For best results: (1) Check the course start page._ (2) Enroll in the course. (3) Start learning and practicing!
Learn to build your own NLP text classifier and expose it as an API using the following technologies:
- AI-based text analysis with Tensorflow/Keras;
- Astra DB, a Database-as-a-Service built on Apache Cassandra®;
- FastAPI, the high-performance Python framework for creating APIs;
- Many useful Python libraries and packages including
pandas,pydantic,dotenv,sklearn,uvicorn, and more.
During this hands-on workshop, you will:
- prepare the labeled dataset for model training;
- train the model to classify any input text;
- export the trained model and test it interactively;
- create your free NoSQL database for data storage;
- set up and start an API exposing the classifier as a reusable class;
- learn how to speed up the API with DB-based caching;
- inspect how a streaming response is handled in the API.
Prerequisites:
- Familiarity with Python;
- A Github account is required for the hands-on.
