Synthetic Data

Artificially generated data used to train, fine-tune or evaluate models.

Definition

Synthetic data can fill gaps, protect privacy and create rare scenarios. LLMs generate instruction pairs and evaluation sets; simulators such as NVIDIA Omniverse and Cosmos generate vision and physical-AI data. It must be checked for quality, bias and collapse from recursive training.

Exam tip

Synthetic data helps with scarce or sensitive data but must be validated for quality and bias.
