High-accuracy data processing and machine learning techniques for sensitive data

摘要

Flexible, high-accuracy data processing techniques and accompanying systems avoid criticality in intermediate computations through intelligent, low cost sanitization of data operations. A data processing operation including one or more plans is received, with each plan having a data operation described as a tree based-structure. The plans that are determined to create criticality on execution are sanitized by transforming the plan itself, ancestors, and/or children of the plan. Determining whether execution of a plan creates criticality is based on the determination of whether a set of criticality conditions includes data signals that are associated with the plan. After sanitization, the data processing operation can be fully executed without criticality arising in intermediate operations.
