🚀 When Model Performance Drops in Production
In one of my interviews, I was asked:
👉 “What would you do if your model performance degrades over time?”
🧠 My approach
I start by checking Data Drift.

This means:
👉 the data in production is different from training data.
And when that happens, even a good model starts failing.
⚙️ Simple first step
I don’t jump into complex methods.
I start with:
Compare mean of training data
Compare mean of new data
Measure the difference
Use a threshold to detect drift
🎯 Final thought
Start simple.
Detect the change early.
Then improve the system.
