Abstract
Energy theft in smart grids is a widespread challenge that impacts utility providers and consumers. It undermines the financial stability of utility companies, introduces electrical safety risks, and contributes to increased energy costs. The advancement of machine learning (ML) combined with the amount of data produced by smart grids can help resolve the problem by building efficient detection ML models. Data privacy is a hugely controversial issue in this case. Federated learning (FL) can be used to rescue as it enables the training of ML models while preserving data privacy by keeping data localized. However, it suffers compatibility issues, high communication costs, security threats, and scalability challenges. To address these limitations, this paper proposes to use hierarchical federated learning (HFL) for energy theft detection, where intermediate aggregations occur at edge servers, resolving compatibility issues, significantly reducing communication costs and enhancing scalability. It demonstrates how the novel HFL approach can efficiently manage and process data from distributed sources. Our experimental results demonstrate an 88% reduction in communication overhead and high scalability compared to FL. In terms of accuracy and computational efficiency, our approach is comparable to both FL and centralized ML.

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 it
