What is Testing and Validation
The process of checking whether a model, dataset, or AI system behaves correctly and meets requirements.
Definition
Testing and Validation is the process of checking whether a model, dataset, or AI system behaves correctly and meets requirements. In practical AI work, it helps teams connect a concept to data, model behavior, product choices, evaluation, and risk. The useful question is not only what the term means, but how it affects quality, cost, reliability, safety, and decisions in a real workflow.
Example
An engineering team uses Testing and Validation to make model development, deployment, or evaluation more reliable.
Why it matters
Testing and Validation matters because the process of checking whether a model, dataset, or AI system behaves correctly and meets requirements can change how teams build, evaluate, choose, or govern AI systems. It affects cost, reliability, latency, security, and how easily an AI feature can move from a demo to production.
How it works
Teams connect data, compute, model artifacts, libraries, monitoring, access control, and deployment tools into a repeatable workflow. For Testing and Validation, the key is to connect the definition with inputs, assumptions, measurable outcomes, and deployment limits.
Where it is used
- Used in model training, inference, data processing, deployment, evaluation, monitoring, and developer tooling.
Limitations
Infrastructure choices can lock teams into particular costs, vendors, latency profiles, security constraints, or operational complexity.
