Abstract
A machine learning model for classifying different lighting loads based on properties of electrical current through the loads is built. The model is applied to electrical data gathered based on powering a target lighting load in order to classify the load. Based on load classification, operating parameter(s) to control operation of a dimmer to control power to the load are selected and the dimmer is configured with the selected parameter(s) to achieve desired dimmer operation in dimming the load.
