Predictive Maintenance at the Edge: An Embedded Anomaly Detection Pipeline Trained with Quantum Optimization

Filipe Chagas Ferraz

This article presents a predictive-maintenance pipeline that detects anomalies in bearings from vibration signals, adapted for deployment at the edge on low-cost microcontrollers, and that uses quantum optimization in two steps of its training. The pipeline consists of a step of vibration feature extraction and a step of classification with a one-class support vector machine (OCSVM). The features are selected by minimum redundancy and maximum relevance (mRMR) with the variational quantum eigensolver (VQE), under a limit on computing time. The OCSVM is adapted for inference at the edge without floating-point operations and is trained by a variational quantum algorithm with Pauli-correlation encoding (PCE). In small-scale tests on a simulator, with the Paderborn bearing dataset, the VQE found the optimal selection in 36% of the runs with Adam, and PCE chose better support vectors than chance, until a classical local search made the two equal. A classical baseline, the usual OCSVM trained by SMO with its weights rounded, matched them without any search.

Quantum-Enhanced Support Vector Machine for Sentiment Classification

Fariska Zakhralativa Ruskanda, Muhammad Rifat Abiwardani, Rahmat Mulyawan +2 more

The use of quantum technology in NLP tasks, especially sentiment classification, has the potential to be developed. In this research, we investigate the best technique to represent sentiment sentences so that sentiment can be analyzed using the Quantum-Enhanced Support Vector Machine (QE-SVM) algorithm. Investigations were carried out using circuit parameter optimization methods and data transformation. The pipeline of the proposed method consists of sentence-to-circuit conversion, circuit parameter training, statevector formation, and finally the training and testing processes. As a result, we obtained the best classification results with an accuracy of 93.33% using the SPSA optimization method and PCA transformation data. These results have also outperformed the baseline SVM method.

Training support vector machines: a quantum-computing perspective

Davide Anguita, Sandro Ridella, Fabio Rivieccio +1 more

Recent advances in characterizing the generalization ability of support vector machines (SVMs) exploit refined concepts, such as Rademacher estimates of model complexity and nonlinear criteria for weighting empirical errors. Those methods improve the SVM representation ability and tighten generalization bounds. On the other hand, quadratic-programming algorithms are no longer applicable, hence the SVM-training process cannot benefit from the notable efficiency featured by those specialized techniques. The paper considers the possibility of using quantum computing to solve the resulting problem of effective optimization, especially in the case of digital SV implementations. The behavioral aspects of conventional and enhanced SVMs are compared, supported by experiments in both a synthetic and a real-world problem. Likewise, the related differences between quadratic-programming and quantum-based optimization techniques are analyzed.
