Adaptive Weighted Recurrence Graph for Appliance Recognition in Non-Intrusive Load Monitoring

This repository is the official implementation of Adaptive Weighted Recurrence Graph for Appliance Recognition in Non-Intrusive Load Monitoring. This paper proposes hyper-parameter free weighted recurrence graphs block (AWRG) for appliance feature representation in NILM and apply Convolutional Neural Networks for classification. The proposed AWRG block is included in the learning pipe-line as part of the end-to-end feature learning with deep learning networks. We conduct an extensive evaluation of two datasets collected from residential and industrial environments. In contrast to other approaches that use sub-metered data, we test our method on aggregated power measurements, which is much more realistic. Furthermore, we contrast the multi-dimension three-phase system in industrial settings and the single-phase system in residential buildings, which is not common in the literature.

This package contains a Python implementation of Adaptive Recurrence Graph for Appliance classification in NILM.
