Whole-house Non-Intrusive Appliance Load Monitoring via multi-label classification
Bibliographic record
Abstract
Non-intrusive appliance load monitoring is a technique to help power companies monitor and analyze residential energy usage. Aggregated power load measurements are disaggregated into individual appliance loads by examining the appliance-specific power consumption characteristics. This data can then be used to modify consumer behaviors via detailed billing data and/or demand-pricing tariffs. A number of advances in the field have been reported in the past two decades, many of which apply machine learning algorithms. However, these algorithms only assign one label to an example, which is a poor match to the NIALM problem, meaning elaborate encodings or classifier ensembles are needed for NIALM. A more elegant solution would be to use algorithms that assign multiple labels to a single example. These multi-label classification algorithms have received very little attention in this field to date. We conduct an experimental investigation of four multi-label classification algorithms for non-intrusive monitoring, and find that they are superior to all prior reported results on a real-world household dataset.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
