classifier
What It Means
A classifier is an AI model that sorts data into predefined categories or groups by analyzing patterns in the input data. Instead of predicting a number or continuous value, it assigns labels like 'approved/denied,' 'high risk/low risk,' or 'spam/not spam' based on what it has learned from training examples.
Why Chief AI Officers Care
Classifiers are among the most common AI applications in business, powering everything from fraud detection to hiring decisions, making them a primary source of both value creation and regulatory risk. When classifiers make biased or incorrect categorizations, they can expose companies to discrimination lawsuits, regulatory penalties, and damaged customer relationships while undermining business objectives.
Real-World Example
A bank uses a classifier to automatically categorize loan applications as 'approve,' 'deny,' or 'needs human review' by analyzing factors like credit score, income, and employment history. The model learned these patterns from thousands of previous loan decisions and their outcomes.
Common Confusion
People often confuse classifiers with predictive models that forecast numbers, but classifiers specifically put things into buckets or categories rather than predicting quantities like sales revenue or stock prices.
