SincNet-RNN Hybrid Neural Network for Detecting Industrial Faults Through Ultrasonic Signal Processing
Bibliographic record
Abstract
Recent developments in condition monitoring and industrial fault prediction are increasingly utilizing intelligent techniques to enhance reliability, productivity, and safety. This study explores the integration of ultrasonic signal processing with various machine learning (ML) models to significantly improve the accuracy of industrial fault diagnosis. Specifically, it employs a hybrid neural network (NN) approach using Sine-NET algorithms to analyze ultrasonic data. A modified architecture, combining SincNet with BiLSTM networks, was designed to harness the strengths of each for detecting industrial faults. The SincNet layer provides efficient feature extraction by adapting filters to relevant frequencies in the raw ultrasonic data, while BiLSTM enhances temporal analysis, capturing fault patterns over time. By incorporating a tailored bandpass filter bank, the model further enhances BiLSTM's hierarchical analysis capability, enabling it to leverage the sinc-layer for efficient feature extraction from raw waveforms and to adapt filters more precisely to the application's requirements. The proposed model demonstrated 96% accuracy with minimal variance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
