Abstract

fetched live from OpenAlex

Non-intrusive load monitoring (NILM) is a promising approach for recognizing various electrical equipment energy usage patterns from aggregate load data. In this paper, we investigate the development of an NILM model to achieve high recognition accuracy, ensure a small model size for lightweight implementation, and enhance its adaptability to a wide range of appliance types. Specifically, we propose a framework named DCML, which employs dilated convolution to precisely control the receptive field, allowing efficient adjustments in feature extraction granularity to meet the specific requirements of different appliances. In addition, multi-task learning techniques are incorporated to allow simultaneous recognition of multiple appliances from a single model, saving model space while ensuring high recognition accuracy. Compared to the benchmark, our model reduces the recognition mean absolute error (MAE) by $36.8 \%, 16.8 \%$, and $43.8 \%$ for fridges, microwaves, and washing machines, respectively. Furthermore, the proposed DCML can significantly save the storage space of convolutional layers when simultaneously recognizing multiple appliances.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
