Center node: "complexity of power draws for load disaggregation"
  Abstract: Non-Intrusive Load Monitoring (NILM) is a technology offering methods to identify appliances in homes based on their consumption characteristics and the total household demand. Recently, many different novel NILM approaches were introduced, tested on real-world data and evaluated with a common evaluation metric. However, the fair comparison between different NILM approaches even with the usage of the same evaluation metric is nearly impossible due to incomplete or missing problem definitions. Each NILM approach typically is evaluated under different test scenarios. Test results are thus influenced by the considered appliances, the number of used appliances, the device type representing the appliance and the preprocessing stages denoising the consumption data. This paper introduces a novel complexity measure of aggregated consumption data providing an assessment of the problem complexity affected by the used appliances, the appliance characteristics and the appliance usage over time. We test our load disaggregation complexity on different real-world datasets and with a state-of-the-art NILM approach. The introduced disaggregation complexity measure is able to classify the disaggregation problem based on the used appliance set and the considered measurement noise.
