Abstract

fetched live from OpenAlex

Classical Weibull distribution (Weibull minima) is gaining momentum due to its employment in wind speed estimation for the growing renewable energy field. The main difficulty of Weibull distribution is that it is hard to accurately estimate its parameters for a set of wind speed data. Much research has been involved in this task with varying complexity, success, and accuracy. Statistical analysis is usually used to compare the accuracy of proposed Weibull parameters estimation methods. As the Weibull parameters of a set of data are not normally estimated, for simulation, more than once, this research considered the processing time to be of far less importance than accuracy. In this research, efforts were made to make the best use of the current PC processing power to achieve the best possible accuracy of the Weibull parameters. In the current research, an iterative technique is proposed to directly estimate the Weibull parameters that yield the best results with the most employed statistical analysis; least Root Mean Square Errors of estimation (RMSE). The results of the new technique were compared to that of the Maximum likelihood method (MLM), and a considerable improvement in accuracy, 9.3 % was achieved.

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.
