In the wake of data-driven decisions, AI systems depend on customer data for training and improving their models. It is important for such systems to maintain the user’s privacy and trust, and follow compliance regulations like GDPR.<\/p>\n\n\n\n
GDPR is a European Union law designed to protect individuals\u2019 personal data. It gives users rights over their data and mandates businesses to use that data responsibly.<\/strong><\/p>\n\n\n\n Best Practices for Privacy-Compliant AI Training:<\/strong><\/p>\n\n\n\n Here\u2019s how to use TensorFlow Privacy to train a model with differential privacy:<\/p>\n\n\n\nKey GDPR Principles Relevant to AI:<\/h3>\n\n\n\n
