control class
What It Means
A control class is a baseline group that doesn't receive any AI intervention or experimental treatment, used to measure whether your AI system actually creates the business impact you think it does. It's like having a group of customers who continue using the old process while others get the new AI-powered experience, so you can compare results. Without this comparison group, you can't prove your AI investment is working.
Why Chief AI Officers Care
Control classes are essential for proving ROI on AI investments and avoiding costly mistakes based on false assumptions about AI performance. They help CAIOs demonstrate concrete business value to executives and boards, while also identifying when AI systems aren't actually improving outcomes. This evidence-based approach protects against wasting resources on AI solutions that feel innovative but don't deliver measurable results.
Real-World Example
An insurance company implements an AI chatbot for claims processing but keeps 20% of customers using the traditional phone-based system as a control group. After three months, they can compare resolution times, customer satisfaction scores, and operational costs between the AI-assisted group and the control group to prove whether the chatbot actually improved performance or just shifted problems around.
Common Confusion
People often think any comparison group is a control class, but true controls must be randomly selected and receive no AI treatment whatsoever. Many organizations mistakenly compare their new AI system against historical data rather than maintaining a proper control group running simultaneously.

Technical Definitions
NISTNational Institute of Standards and Technology
"(control group) the set of observations in an experiment or prospective study that do not receive the experimental treatment(s). These observations serve (a) as a comparison point to evaluate the magnitude and significance of each experimental treatment, (b) as a reality check to compare the current observations with previous observation history, and (c) as a source of data for establishing the natural experimental error."Source: nist_statistics_2012
