Claim 14:
15. A computing system for auditing the results of a machine learning model, the system comprising:
a processor;
a memory operably connected to the processor;
a sensor interface operably connected to the processor and memory;
a non-transitory computer-readable medium operably connected to the processor and memory and storing computer-executable instructions that when executed by at least a processor of a computer cause the computer to:
retrieve a set of state estimates for original time series data values received through the sensor interface from a database under audit, wherein the state estimates were generated by a state estimation computation for each of the time series data values;
reverse the state estimation computation for each of the state estimates to produce reconstituted time series data values for each of the state estimates;
retrieve the original time series data values from the database under audit;
compare the original time series data values pairwise with the reconstituted time series data values to determine whether the original time series and reconstituted time series match; and
generate a signal that the database under audit (i) has not been modified where the original time series and reconstituted time series match, and (ii) has been modified where the original time series and reconstituted time series do not match.
