QoA4ML consists of a set of utilities and specs for supporting quality of analytics in ML services. Especially, we focus on ML services across edge-cloud continuum, which are built as a composition of services.
The design of QoA4ML specification is in language
Developers can call many functions from a QoAClient and QoA4ML's utilities to evaluate/report ML-specific attributes (e.g., data quality, inference performance), build the quality reports, and send them to the observation services. The QoAClient can be initiated with various configurations for specifying observation server and communication protocols (e.g., messaging) in different formats (e.g., json and yaml).
The detail documents for QoA4ML utilization is presented in qoa4ml_lib
For a local build and use QoA4ML one can do:
$python3 -m pip install build
$cd qoa4ml_lib/
$python -m buildQoA Reports are implemented in QoA4ML Utilities, an object supports developers in reporting metrics, computation graphs, and inference graphs of ML services in a concrete format.
Examples are in examples.
The code is in observability
QoA4ML Monitor is a component monitoring QoA for a ML model which is deployed in a serving platform.
- Monitoring Service: third party monitoring service used for managing monitoring data.
- We use Prometheus and other services: provide information on how to configure them.
- QoA4MLObservabilityService: a service reads QoA4ML specifications and real time monitoring data and detect if any violation occurs
OPA engine is used to implement the service for checking violation under qoa4mlopa
Another new engine is currently developed under rohe_ObService
