Debugging and Understanding ML Classifiers Clearly The Real Problem: Accuracy Is Not Enough Most students stop here: “My classifier gives 91% accuracy. Model is good.” But in real-world ML systems, accuracy alone is dangerous. Imagine: A bank rejecting loans A healthcare model predicting cancer A hiring system filtering candidates Now ask: Why was this decision …
