AI Flow is an open source framework that bridges big data and artificial intelligence. It manages the entire machine learning project lifecycle as a unified workflow, including feature engineering, model training, model evaluation, model service, model inference, monitoring, etc. Throughout the entire workflow, users can choose to use the computing engine like Python, Flink etc.
In addition to the capability of orchestrating a group of batch jobs, by leveraging an event-based scheduler(enhanced version of Airflow), AI Flow also supports workflows that contain streaming jobs. Such capability is quite useful for complicate real-time machine learning systems as well as other real-time workflows in general.
You can use AI Flow to do the following:
-
Define the machine learning workflow including batch/stream jobs.
-
Manage metadata(generated by the machine learning workflow) of date sets, models, artifacts, metrics, jobs etc.
-
Schedule and run the machine learning workflow.
-
Publish and subscribe events
To support online machine learning scenarios, notification service and event-based schedulers are introduced.
AI Flow's current components are:
-
SDK: It defines how to build a machine learning workflow and includes the api of the AI Flow.
-
Notification Service: It provides event listening and notification functions.
-
Meta Service: It saves the meta data of the machine learning workflow.
-
Event-Based Scheduler: It is a scheduler that triggered jobs by some events happened.
You can follow our Quick Start to get your hands on AI Flow quickly. Besides, you can also take a look at our Tutorial to learn how to write your own workflow. You can use AI Flow according to the guidelines of.
Please refer to the Python API to find the details of the API supported by AI Flow.
