unsupervised learning
What It Means
Unsupervised learning is when AI systems find hidden patterns or groupings in data without being told what to look for or what the 'right' answers are. The system explores data on its own and discovers natural clusters, relationships, or structures that humans might not have noticed or defined beforehand.
Why Chief AI Officers Care
This approach can uncover valuable business insights that weren't previously known, such as new customer segments, fraud patterns, or operational inefficiencies that traditional analysis missed. However, it requires careful validation since there's no built-in way to verify if the patterns the AI discovers are actually meaningful or actionable for the business.
Real-World Example
A retail company uses unsupervised learning on customer purchase data and discovers five distinct shopping behavior groups they never knew existed - like 'weekend bulk buyers' and 'seasonal discount hunters' - allowing them to create targeted marketing campaigns for each newly identified segment without having predefined these categories.
Common Confusion
People often think unsupervised learning means the AI is completely autonomous and needs no human guidance, but it actually requires significant human expertise to interpret results and determine which discovered patterns are business-relevant versus just statistical noise.

Technical Definitions
NISTNational Institute of Standards and Technology
"A learning strategy that consists in observing and analyzing different entities and determining that some of their subsets can be grouped into certain classes, without any correctness test being performed on acquired knowledge through feedback from external knowledge sources. Note 1 to entry: Once a concept is formed, it is given a name that may be used in subsequent learning of other concepts."Source: iso_2382_1997
