Abstract

fetched live from OpenAlex

This paper presents an empirical investigation on fluctuation and trend of added value changes in oil and gas industries and their products and also to anticipate the current added value of these industries. For this aim, fluctuation of added values of different subsidiaries such as oil group products, exporting crude oil, production of gas and petroleum is investigated over the period 1959-2004. The study selects the best network to anticipate added value in subsidiaries of energy section. For the training and testing the network, all data are divided into two groups. To define input layer neurons number which are equal to auto regressive vector rank in ARMA method, the rank of auto regressive (p) and mobile mean (q) have been used according to proposed method of Pesaran & Pesaran. The simulated results have been extracted by using neural networks, in feed forward network which had low compatibility with the real added value.

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.
