Use case
Train Machine Learning Models
Source properly licensed training and evaluation data for machine learning model development.
The problem ML teams need enough relevant, well-labeled and properly licensed data to train and evaluate models, and sourcing this responsibly is often the hardest part of a project.
Data you'll need
- Domain-specific training data
- Labeled/annotated evaluation sets
- Clear commercial usage rights
Recommended provider types
