Abstract
In actual industrial sites, the application of bearings is becoming increasingly widespread. In order to better monitor the faults of bearings, this article combines the concept of deep learning and designs a bearing fault diagnosis and monitoring software system based on lightweight neural networks to resist coloured noise. This system is developed based on MATLAB App Designer. When testing the system, five different bearing datasets, namely MFPT, Paderborn, IMS, Ottawa, and CWRU, are applied. Considering that the data in actual scenarios contains complex noise, coloured noise signals are added. Compared to traditional fault diagnosis software that requires pre writing data into the program, this software can perform real-time processing on any single column vibration data file. By using lightweight neural network methods to preprocess the data collected by sensors, the SqueezeNet network has a faster speed to extract significant features of vibration. This software system can achieve time-frequency domain image output of signals, with multiple noise reduction methods. It can also calculate the frequency of faults based on bearing model data. Through envelope spectrum images, the location of faults can be monitored and email reminders can be sent to engineers.

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
