Definition ∞ Private model training involves developing machine learning models using sensitive data without exposing the raw information to the model trainers or other parties. This is achieved through cryptographic techniques like federated learning or homomorphic encryption, which allow computations on encrypted data. It ensures data confidentiality during the critical phase of algorithm development. This method is vital for privacy-sensitive applications in AI.
Context ∞ The current research focuses on enhancing the efficiency and accuracy of private model training techniques, particularly for decentralized AI applications and data marketplaces. A key debate involves the computational overhead associated with these privacy-preserving methods and their impact on model performance. Future developments will include more robust cryptographic primitives and standardized protocols to facilitate secure and private collaborative AI model development.
