Quality Impact

Model performance and behavior are heavily influenced by training data. Biased, incomplete, or low-quality training data leads to biased or poor models.

Data Governance

Training data must be documented: source, collection method, size, representativeness, known biases, and how it was preprocessed or filtered.

Regulatory Scrutiny

Regulators increasingly require organizations to document and justify training data choices, especially for high-risk systems. Using proprietary or sensitive data in training may create legal and ethical issues.
