Data verification

The process of confirming that the data is accurate or true.

The Explain card

Plain English
Data verification is the process of confirming that data is accurate or true, checking it against a trusted source or expected rules before anyone relies on it.
Example
Before adding a threat intelligence feed to a training set, analysts verify a sample of indicators against independent sources and find a chunk of stale false positives.
Why it matters
Models learn what they are shown, true or not. Verification is the gate that keeps fabricated records, mislabelled examples and attacker-planted entries out of the learning process.
Hook
Trust, but verify, before you train.
