Abstract

fetched live from OpenAlex

The essence of Non-Intrusive Load Monitoring (NILM) is to extract electricity consumption details of individual appliance from an aggregated house-level electrical measurement at the main panel without sub-metering each appliance. In this paper, an Expectation Maximization (EM) based semi-supervised multi-label classification technique is applied in NILM. It requires a one-time registration of individual appliance to obtain few samples during the training stage. After that, the total electricity is utilized to detect the states of each appliance and analyze electricity consumption information of individual appliance for each instance via the help of semi-supervised learning method. Experiments on house 1 and house 3 dataset of Reference Energy Disaggregation Dataset (REDD) verify the effectiveness of application of Semi-supervised learning techniques in NILM.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
