Constructing explainable health indicators for aircraft engines by developing an interpretable neural network with discretized weights @article{472b2745ccd940f69e22eade59c060eb, title = "Constructing explainable health indicators for aircraft engines by developing an interpretable neural network with discretized weights", abstract = "Abstract: Remaining useful life predictions depend on the quality of health indicators (HIs) generated from condition monitoring sensors, evaluated by predefined prognostic metrics such as monotonicity, prognosability, and trendability. Constructing these HIs requires effective models capable of automatically selecting and fusing features from pertinent measurements, given the inherent noise in sensory data. While deep learning approaches have the potential to automatically extract features without the need for significant specialist knowledge, these features lack a clear (physical) interpretation. Furthermore, the evaluation metrics for HIs are nondifferentiable, limiting the application of supervised networks. This research aims to develop an intrinsically interpretable ANN, targeting qualified HIs with significantly lower complexity. A semi-supervised paradigm is employed, simulating labels inspired by the physics of progressive damage. This approach implicitly incorporates nondifferentiable criteria into the learning process. The architecture comprises additive and newly modified multiplicative layers that combine features to better represent the system{\textquoteright}s characteristics. The developed multiplicative neurons are not restricted to pairwise actions, and they can also handle both division and multiplication. To extract a compact HI equation, making the model mathematically interpretable, the number of parameters is further reduced by discretizing the weights via a ternary set. This weight discretization simplifies the extracted equation while gently controlling the number of weights that should be overlooked. The developed methodology is specifically tailored to construct interpretable HIs for commercial turbofan engines, showcasing that the generated HIs are of high quality and interpretable.", keywords = "Artificial neural network, Feature fusion, Interpretable health indicator, Multiplicative neuron, Prognostics and health management, Ternary weights", author = "Morteza Moradi and Panagiotis Komninos and Dimitrios Zarouchas", note = "Green Open Access added to TU Delft Institutional Repository {\textquoteleft}You share, we take care!{\textquoteright} – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.

A generalized machine learning framework to estimate fatigue life across materials with minimal data @article{78ef63b339ed4fd991345d91f24c42f3, title = "A generalized machine learning framework to estimate fatigue life across materials with minimal data", abstract = "In this research, a generalized machine learning (ML) framework is proposed to estimate the fatigue life of epoxy polymers and additively manufactured AlSi10Mg alloy materials, leveraging their failure surface void characteristics. An extreme gradient boosting algorithm-based ML framework encompassing Synthetic Minority Over-sampling TEchnique (SMOTE), categorical data encoding, and external loop cross-validation is developed to evaluate the fatigue life across materials. The influence of different training strategies based on materials, input features, encoding method, and data standardization on the model performance is explored. Additionally, the importance of anti-data-leakage and anti-overfitting measures over the ML model performance is addressed. The result shows that the data-leakage-free, external loop cross-validated model can estimate the fatigue life of selective epoxy polymers and metal alloys with an average R2 of 0.71 ± 0.06 using a mere 12 to 27 experimental data points per material category. Whereas the model trained with data-leakage and overfitting results in high R2 of 0.9.", keywords = "Composites, Fatigue, Machine learning, Metal alloys, Minimal data, Void", author = "Srinivasan, \{Dharun Vadugappatty\} and Morteza Moradi and Panagiotis Komninos and Dimitrios Zarouchas and Vassilopoulos, \{Anastasios P.\}", year = "2024", doi = "10.1016/j.matdes.2024.113355", language = "English", volume = "246", journal = "Materials and Design", issn = "0264-1275", publisher = "Elsevier", } .
