Abstract
Bearing fault diagnosis methods based on deep learning usually require a large number of training samples. However, obtaining large amounts of faulty bearing data can be challenging. How to diagnose faults with limited or few samples becomes a research problem. In order to solve the problem of bearing fault diagnosis with few samples, a rolling bearing fault diagnosis method based on improved Adam (Adaptive Moment Estimation) is proposed. First, it combines the advantages of both Adam and AmsGrad optimizers. Second, similar to AdamP, AmsGradP (Adaptive Gradient Optimizer with Penalty Parameters) introduces the penalty term of the parameter norm to mitigate the problem of premature decay of the learning rate. Finally, by penalizing the norm of the parameter during optimization, AmsGradP can prevent excessive parameter growth, thus further stabilizing the learning rate. The experimental results show that when only 1.58% of the data is used as the training dataset, the average accuracy of 98.26% can be achieved by using the AmsGradP optimizer, which is 6.68% higher than that by using the Adam optimizer.

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
