Special Issue Information

Dear Colleagues,

With advancements in ICT technology introducing new technologies, such as mobile technology, IoT, and sensors, organizations are now faced with an environment where they generate and utilize vast and diverse types of big data. While traditional data analysis has focused on hypothesis verification based on correlations between structured data, the big data era is increasingly involving the discovery and verification of hypotheses considering both structured and unstructured data. 

Artificial intelligence (AI) technology, particularly methods derived from machine learning and the rapidly developing area of deep learning, is gaining attention as a powerful tool for such big data analyses. These new AI technologies are being applied across various fields, offering solutions to problems previously unsolvable by humans, and have become significant both academically and industrially. 

As a result, AI has become a crucial element in maintaining sustainable competitiveness for various stakeholders and is an area of keen interest to many researchers. 

This Special Issue will explore creative analytical models and generate innovative results using big data analysis and data mining approaches grounded in new AI technologies. 

Topics of interest for this Special Issue include, but are not limited to, the following: 

- AI systems for business applications;

- Big data analytics of customer behavior;

- Data mining in healthcare and forensic science;

- AI-based image reconstruction and recognition technology;

- Machine learning applications for financial market predictions;

- Novel methods in big data analytics;

- Text mining applications.

The aim of structural reliability assessment (SRA) is to guarantee the safety, durability, and performance of structures; however, traditional methods like stochastic finite element analysis (SFEA) can be computationally prohibitive to use in practical situations. This paper introduces a novel framework for SRA utilizing deep neural networks (DNNs) implemented in an open-source program called TRA-DNN, replacing the resource-intensive finite element (FE) analysis with a DNN model. The DNN is trained using 6874 FE column models, including factors like geometric imperfections, resulting in a training database with 419,314 data records. It accurately predicts axial load-deformation curves for corroded steel CHS columns, enabling the determination of the ultimate capacities for columns with varying properties. The model’s accuracy is confirmed through rigorous quantitative and qualitative validation, including various failure modes. TRA-DNN employs the DNN model to perform SRA via Crude Monte Carlo Simulation (MCS), yielding results that are in high agreement with conventional SFEA, yet with significantly reduced computational time (1,388,250 times faster). In addition, TRA-DNN can be used to estimate the service life of CHS columns considering both corrosion propagation and load increase with time. Future research can utilize TRA-DNN to optimize column design and maintenance to minimize both risk and cost. Full article

This study presents a systematic comparison of three dimensionality reduction methods namely Principal Component Analysis (PCA), t-Distributed Stochastic Neighbor Embedding (t-SNE), and uniform manifold approximation and projection (UMAP) applied to multivariate turbofan engine sensor data from the NASA C-MAPSS benchmark. The analysis was conducted across three subsets of increasing complexity: FD001 (single operating condition, single-fault mode), FD002 (six operating conditions, single-fault mode), and FD004 (six operating conditions, two fault modes), comprising 20,631, 53,759, and 61,249 observations respectively. For multi-condition subsets, within-condition z-score normalization was applied to prevent inter-condition offsets from masking the degradation signal. Fourteen informative sensor variables were retained following the exclusion of near-constant sensors. Embedding quality was assessed using four complementary metrics: silhouette score (with bootstrap 95% confidence intervals), trustworthiness, continuity, and PCA reconstruction RMSE. A downstream remaining useful life (RUL) prediction task and a hyperparameter sensitivity analysis were also conducted. PCA achieved the best silhouette scores on FD001 (0.4608; 95% CI = [0.447, 0.475]; and FD002) and demonstrated RUL predictive capabilities similar to those of a 14-Dimensional Baseline Model, which supports the ability of PCA to be used as an interpretable tool for analyzing data globally. t-SNE maintained the highest levels of trustworthiness and continuity in preserving local neighborhood relationships among the models tested across each subset. UMAP had the best silhouette score on FD004 (0.4818; 95% CI = [0.463, 0.495]); UMAP also produced confidence intervals that did not overlap with either PCA or t-SNE, thus showing significant statistical differences when compared to these two methods under conditions involving multiple faults. The PCA ranking was consistent across the range of hyperparameter combinations tested (n = 36). The results provide a quantitative, generalizable framework for dimensionality reduction method selection in prognostic health management applications. Full article
