Improving smart grid system management is crucial in the fight against climate change, allowing consumers to actively participate is a challenge for electricity suppliers.
Non-Intrusive Load Monitoring (NILM) aims to estimate power consumption of individual appliances using the main smart meter signal, which aggregates consumption making it hard to distinguish.
The newly introduced CamAL is a weakly supervised approach for appliance pattern localization, requiring only information on appliance presence to be trained.
CamAL combines deep-learning classifiers and an explainable classification method, outperforming existing weakly supervised baselines and demanding significantly fewer labels than fully supervised NILM approaches.
