## Choose when

### Choose awesome-automl-papers if…

- License: awesome-automl-papers is Apache-2.0, metric-learn is MIT.
- Tags unique to awesome-automl-papers: automl, feature-engineering, hyperparameter-optimization, neural-architecture-search.
- Also covers Evaluation & Observability.
- When you need a curated list of academic materials to research or learn about AutoML technologies

### Choose metric-learn if…

- License: metric-learn is MIT, awesome-automl-papers is Apache-2.0.
- Requirements: The application requires Python version 3.6 or higher and specific dependencies such as numpy, scipy, and scikit-learn..
- Tags unique to metric-learn: machine-learning, metric-learning, python, scikit-learn.
- When you need to use specific metric learning techniques such as Large Margin Nearest Neighbor (LMNN) or Neighborhood Components Analysis (NCA), which are implemented efficiently in Python.

## When NOT to use awesome-automl-papers

- If looking for direct integration with commercial AutoML systems, as the tool provides only a list of academic papers and resources
- When seeking practical AutoML solutions to directly apply in production settings without extensive customization or interpretation from papers

## When NOT to use metric-learn

- If your development environment does not already use Python, as metric-learn is specific to this language and its ecosystem.
- For applications that require real-time performance critical operations, since the library may rely on computationally intensive algorithms that could affect latency in real-time systems.
