NB: members must have two-factor auth. The IMS bearing data provided by the Center for Intelligent Maintenance Systems, University of Cincinnati, is used as the second dataset. the following parameters are extracted for each time signal signal: Looks about right (qualitatively), noisy but more or less as expected.
Lets train a random forest classifier on the training set: and get the importance of each dependent variable: We can see that each predictor has different importance for each of the transition from normal to a failure pattern. change the connection strings to fit to your local databases: In the first project (project name): a class .
