calibration
What It Means
Calibration is the process of comparing your measurement tools or systems against known, trusted standards to determine how accurate they are. It involves figuring out exactly how much your instrument is 'off' from the true value and documenting that difference with a known level of uncertainty.
Why Chief AI Officers Care
For AI systems, calibration ensures that data inputs, sensor readings, and measurement systems feeding your models are accurate and reliable. Poor calibration can lead to biased training data, incorrect model predictions, and ultimately failed AI implementations that don't perform as expected in production environments.
Real-World Example
An autonomous vehicle company must calibrate all the LiDAR sensors, cameras, and GPS units in their test fleet against precise reference standards before collecting training data. Without proper calibration, a camera might consistently read distances as 10% shorter than reality, causing the AI to learn incorrect spatial relationships and potentially leading to accidents.
Common Confusion
People often think calibration is a one-time setup activity, but it's actually an ongoing process since measurement tools drift over time. Calibration is also frequently confused with validation - calibration tells you how far off your instrument is, while validation confirms whether your overall system meets requirements.

"A comparison between a device under test and an established standard, such as UTC(NIST). When the calibration is finished, it should be possible to state the estimated time offset and/or frequency offset of the device under test with respect to the standard, as well as the measurement uncertainty."Source: CSRC
"operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication"Source: aime_measurement_2022, citing ISO/IEC Guide 99
"Set of operations that establish, under specified conditions, the relationship between values indicated by a measuring instrument or measuring system, or values represented by a material measure, and the corresponding known values of a measurand."Source: UNODC_Glossary_QA_GLP
