Model Selection Strategy

Part of the Data Science Roadmap.

Summary

Choosing the final model isn't just picking the highest metric — interpretability needs, training/inference speed, and maintenance complexity all matter for a real production decision.

How to Learn This

  • 1List the trade-offs (accuracy, speed, interpretability) for 3 models you've trained.
  • 2Practice justifying a model choice that isn't simply 'the one with the highest score'.
  • 3Learn when a simpler, more interpretable model is the right business choice, even if slightly less accurate.
