Goal

NorthPeak technicians write a short description for every incident. Someone then picks the category by hand: bearing_wear, overheating, leak, electrical or sensor_fault. You will train a model that reads the description and proposes the category. The text becomes a TF-IDF matrix. A logistic regression learns from it. You will measure it with an accuracy and a confusion matrix, like in Week 5.

Preview — the rest of the lesson is for enrolled readers.
