Model Parameter Commitment

Definition

Model Parameter Commitment refers to a cryptographic technique where a party publicly commits to the parameters of a computational model, such as a machine learning model, without revealing the actual parameters. This commitment allows others to verify that the model used for a specific computation is indeed the one that was publicly committed to, ensuring transparency and integrity. It is particularly relevant in privacy-preserving machine learning and verifiable computation, where model accuracy and honesty are paramount. This mechanism prevents a party from altering model parameters after a commitment is made.
