Rоtаting-Equipment Fаult A mаintenance team has labeled, оverlapping vibratiоn windows from 100 machines. Each window has RMS (root mean square) amplitude and skewness. The team wants to develop and evaluate an ML system that can predict whether a new machine has a bearing fault. On held-out machines, a trained classifier produces: Actual condition Predicted fault Predicted normal Fault 18 2 Normal 6 74 (2 points) State the ML task, the target, and two input features. (2 points) (a) How would you construct the training and test datasets to train and evaluate the model? (b) If you standardize features during training, how should you standardize the test dataset before evaluating the model? (3 points) Calculate fault-class recall and precision. If missed faults are especially costly, which metric needs special attention, and why? (3 points) A linear SVM confuses two fault patterns; an RBF SVM improves validation results on the same standardized features. Explain what the RBF model can represent that the linear model cannot, and name one check before selecting it for deployment.
