1. A method for identifying a characteristic of a user of a personal care device, the method comprising the steps of:
providing a personal care device comprising a sensor, a controller, and a database;
training the personal care device with training data, comprising the steps of: (i) obtaining, via the sensor, sensor data for at least one personal care session for each of at least two different users of the personal care device; (ii) extracting, via an extraction module of the processor, a plurality of features from each of the personal care sessions; (iii) reducing, using a dimensionality reduction process, the number of extracted plurality of features from one or more of the personal care sessions; and (iv) training, using the reduced number of extracted plurality of features, a classifier to identify a characteristic of each of the at least two different users of the personal care device;
obtaining, via the sensor, sensor data for at least part of a new personal care session initiated by one of the at least two different users of the personal care device;
extracting a plurality of features from the sensor data for the new personal care session; and
identifying, using the trained classifier and the extracted plurality of features from the new personal care session, a characteristic of the user of the personal care device, wherein the identified characteristic of the user is an identification of the user and/or the wherein the identified characteristic of the user is an operating parameter of the user.
