US Patent 11676069 Synthetic data generation using anonymity preservation in computer-based reasoning systems

Techniques for synthetic data generation in computer-based reasoning systems are discussed and include receiving a request for generation of synthetic data based on a set of training data cases. One or more focal training data cases are determined. For undetermined features (either all of them or those that are not subject to conditions), a value for the feature is determined based on the focal cases. In some embodiments, the generated synthetic data may be checked for similarity against the original data, and if similarity conditions are met, it may be modified (e.g., resampled), removed, and/or replaced.
