Ground Truth
The accurate, real-world information used to validate an AI’s predictions or outputs.
Help me explain to...
K–5th
Ground truth is the real answer we compare against. It’s like having the teacher’s answer key to check if your work is right.
6–8th
AI learns from examples and gets checked against the real world. Ground truth is that real-world answer used to test how well it learned.
9–12th
Ground truth refers to verified, correct data that is used to measure the accuracy of an AI model’s predictions. It ensures training and performance are based on reality, not assumptions.
Expeditions
K–5th
Give students a math problem and a finished answer key. Let them self-check. That answer key is their “ground truth.”
6–8th
Give a blurry photo and a clear one. Ask which one is the “real” reference. Connect this to AI needing something accurate to compare against.
9–12th
Have students explore a dataset (like labeled images). Ask them to evaluate if the "truth" labels are accurate and discuss how flawed ground truth can harm AI performance.
