With smart energy meters increasingly available to private households, new applications arise, such as identifying main power consuming devices and predicting human activity. One major obstacle is that smart energy meters typically provide aggregated data, where each source of energy consumption is summed. Further, obtaining training data can be intrusive. To counteract this, we propose an unsupervised minimization approach based on the Inertial Proximal Alternating Linearized Minimization (iPALM) algorithm, utilising convolutional sparse coding to represent individual device energy signatures as atoms convolved with sparse coefficient vectors.
