Abstract
The GM (1,1) model is a prediction method based on the grey system theory, which can be used to handle the prediction problem of time-series data. Compared with the traditional time series model, GM (1,1) model has the characteristics of a simple model, small calculation amount and small samples, so it has a wide application prospect in practical application. Grey GM (1,1) model is a commonly used prediction model in the energy industry, which can effectively deal with small amounts of data and incomplete data, as an accurate, reliable and efficient prediction model to predict energy consumption. In this paper, based on the classical grey GM (1,1) model, the constant free term is introduced, the modified grey GM (1,1) model is proposed, and the least squares method is used to construct an optimization problem related to the model parameters, and finally solve the general expression of the constant free term. Finally, the model is used to predict more accurately the per capita electricity consumption (kilowatt-hours). The results show that the improved GM (1,1) model is better than the traditional GM(1,1) model, which verifies the effectiveness and practicability of the improved model and is suitable for the forecast of per capita electricity consumption.

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
