Abstract

fetched live from OpenAlex

Electricity theft detection (ETD) aims to promptly identify electricity theft by vigilantly monitoring and analyzing atypical electricity consumption time series. Existing machine learning approaches to ETD demand large training sets, leading to degraded performance when limited training samples are available. In this paper, we introduce FL2ETD, a novel few-shot learning framework to ETD. The framework consists of three core components, i.e., a feature extraction module, a representation module, and a classification module. The feature extraction module processes the electricity consumption behavior of users in both the time and the frequency domains to extract distinctive features and increase the number and the diversity of features. The representation module utilizes contrast learning to pre-train unlabeled electricity consumption data for enhancing feature representation quality. The classification module integrates feature representations for making the final decision in ETD. Extensive experiments demonstrate that FL2ETD exhibits superior performance compared to baselines, and its advantage is significant when the number of available training samples is very small (with only 338 samples).

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.
