What it is
NannyML is a Python library that helps in capturing the impact of data drift on model performance after deployment. It allows users to estimate model performance without needing access to target labels, making it invaluable for continuous monitoring and maintenance of machine learning models.
NannyML stands out by offering a robust solution for estimating post-deployment model performance without the need for target labels, making it ideal for continuous monitoring in production environments.
When it fits — and when it doesn’t
A good fit for
Teams needing continuous monitoring of ML models without access to ground truth labels.
Projects where real-time performance estimation is critical for maintaining model reliability.
Look elsewhere if
Scenarios requiring real-time data drift detection and immediate corrective actions.
Environments with limited computational resources, as NannyML requires significant processing power.
Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Performance issues with large datasets
Processing time increases exponentially with dataset size, impacting real-time monitoring capabilities
- 02
Documentation lacks depth and examples
Core concepts are not well-explained, limited practical use cases provided in the documentation
What it does well
Estimates model performance without target labels post-deployment.
Detects data drift and its impact on model performance.
