AI Hardware and Software Can't Measure Without Learning and Re-Learning


To educate the Court as to the "why" of the unreliability of an approved instrument to measure across the measuring interval if it has not been recently calibrated, inspected, maintained, re-calibrated.

It seems strange to think that a modern "approved instrument" has to "learn" - that it has a kind of artificial intelligence. In reality it's true, an approved instrument has to learn the meanings of 67 mg/100mls, 94 mg/100mls, 117 mg/100mls, and 184 mg/100mls. The artificial intelligence uses extrapolation from its response during calibration to known values (from a NIST reference - un étalon with an unbroken chain of connection to SI units of the CGPM/BIPM in Paris) (maybe 0, 50, 100, 200, 300 or 0, 40, 80, 100, 300) that it is shown. This "calibration" is done by the calibrating or re-calibrating technician at the factory or Canadian Authorized Service Centre. A Certificate of Calibration is then prepared. This learning should never take place in the hands of the police. It should be done by a neutral entity that knows what it is doing and follows Standard Operating Procedures.
