Abstract
Earned value management (EVM) is a well-known technique for measuring project performance and progress. Owing to the EVM's attitude to simultaneously combine cost and time performance, project performance can be forecasted accurately, and this plays a vital role in the future of the projects. In the current study, the authors employed an adaptive neuro-fuzzy inference system (ANFIS) as a powerful prediction tool to forecast the completion cost of the projects considering the percentage of risk for qualitative variables and comparing it with other types of neural networks. Because the network structure is usually tuned based on the obtained results, a network optimization procedure is applied using a conventional method for estimating the cost-caused project breakdown. The results showed that ANFIS had a suitable performance (MSE = 0.0003), and based on the sensitivity analysis, the earned value is recognized as the most sensitive factor in the project. This study improves the general estimate of the completion formula by considering the uncertain conditions.

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
