Non-Intrusive Load Monitoring

This page is about the applications of machine learning (ML) in the context of non-intrusive load monitoring (NILM). For an overview of NILM more generally, please see the Wikipedia page on this topic.

A better understanding of the own energy consumption can lead to better energy efficiency by changing one's behavior or exchanging inefficient devices. Machine Learning can be applied to the Nonintrusive load monitoring (NILM) task (also referred to as energy or load disaggregation task), i.e., can help to disaggregate a household's smart meter data and attribute energy consumption to individual devices for increased transparency.
