Abstract
The rolling bearing of the servo motor is widely used in precision-controlled mechanical systems. It usually works at variable speed and load, possibly resulting in partial bearing failure. Meanwhile, the varying conditions may cause the smearing of classable features, increasing the diagnostic difficulty. To this end, an intelligent fault diagnosis method of servo motor-cylindrical roller bearings based on adaptive multiscale convolution manifold embedding networks (AMCMENet) under variable working conditions is proposed. The core of the proposed algorithm is to apply the designed intraclass and interclass constraints to reprocess the feature extracted by designed multiscale convolutional neural networks (MSCNN). In this way, the distribution differences of samples could be improved. The training sample under variable conditions is first input to the designed MSCNN for initial feature extraction. Afterward, the constructed locality sensitive discriminant analysis algorithm module is used, which is adjusted to optimal parameters by the particle swarm optimization algorithm, to enlarge the heterogeneous distance and narrow the homogeneous distance of the extracted feature. Finally, the testing subset is provided to the trained AMCMENet algorithm for fault diagnosis. The experimental results of two datasets demonstrate that the proposed intelligent fault diagnosis method performs better under cross working conditions.

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
