A production-tested approach to Top 7 Mistakes Beginners Make in Machine Learning that covers the edge cases tutorials skip.
There’s a version of Top 7 Mistakes Beginners Make in Machine Learning that looks clean in a tutorial and falls apart the moment real traffic hits it. I’ve written that version. More than once.
This isn’t that version. This is what I actually deploy.

The Problem Nobody Mentions
Most beginner ML tutorials optimize for clarity — not correctness under pressure.
They show clean datasets, perfectly engineered features, and models that converge in minutes. Everything looks deterministic.
Real systems don’t behave like that. Data drifts, pipelines break, and edge cases dominate outcomes.
The gap between “it runs” and “it survives production” is where most beginners struggle — and often don’t even realize why.
Mistake #1: Treating Data Like It’s Clean (It Never Is)
