Learning that “perfect” models fail in production.
Sharing wins & mistakes as I learn. Follow if you’re on the same path 👋

A 99% accuracy score once made me feel unstoppable

Now I know in ML, 99% often screams overfitting
Here’s why learning noise beats you in the real world

[Paddy @paddy_eman]

What helps? Regularization
A penalty for unnecessary complexity.
Focus on signal > noise.
Simple models survive.

[Paddy @paddy_eman]

That’s overfitting.
The model memorizes training data (noise + outliers).
New data shows up and it panics

Think of an athlete who only trains on a flat indoor track 🏃‍♂️
Crushes practice.
Falls apart on real terrain.
They learned the track, not running.
