Enterprise Classification Systems

Foundations ✓ → Models → NLP & advanced → MLOps

Models · 2 — Classify & regress · ~6 min · Module 4: Classification Models

What is this?

Enterprise classifiers need versioning, access control, SLAs, and champion/challenger deploys.

Why should you care?

AIPredict fraud in production is a product, not a notebook.

See it live — copy this example

Use a .NET console or Web API project with Microsoft.ML. Run dotnet run after pasting.

// champion fraud-v3.zip serving; challenger fraud-v4.zip gets 5% traffic
var modelPath = role == "challenger" ? cfg["ChallengerPath"] : cfg["ChampionPath"];

What happened?

  • Gate on metrics.
  • Canary traffic.
  • Rollback.
  • Document owners and data contracts.

Practice next

  1. Champion/challenger paths.
  2. 5% canary.
  3. Rollback runbook.
  4. Compare AUC champion vs challenger daily.
  5. Page on error spike.

Remember

Versioned deploys. Canary. Owners + contracts.

AIPredict fraud product

Canary v4 vs champion v3.

Outcome: Safe promotion when AUC wins.
