synthetic training data
/sin-THET-ik TRAY-ning DAY-tuh/ · noun · AI & Machine Learning · Origin: 2023
Definitions
Training data generated by AI models rather than collected from humans, used to train or fine-tune other models. While dramatically cheaper to produce, synthetic data risks model collapse if used exclusively across generations, as each generation loses fidelity to real-world distributions.
In plain English: Fake data made by one AI to teach another AI, kind of like a teacher writing practice problems instead of using real test scores.
Example: They bootstrapped their specialized medical model using synthetic training data from GPT-4, then fine-tuned on a smaller set of expert-annotated cases.
