Application of Systems Engineering Principles and Techniques in Biological Big Data Analytics: A Review

Abstract: In the past few decades, we have witnessed tremendous advancements in biology, life sciences and healthcare. These advancements are due in no small part to the big data made available by various high-throughput technologies, the ever-advancing computing power, and the algorithmic advancements in machine learning. Specifically, big data analytics such as statistical and machine learning has become an essential tool in these rapidly developing fields. As a result, the subject has drawn increased attention and ma… Show more

“…This can be considered as "big data" in the context of these experiments. Big data in ML is characterized by data volume (size or scale), variety (multitype), velocity (batch or streaming), and veracity (uncertainty, quality, and accuracy) [12][13][14]. ML is about modeling data [15] and Processes 2021, 9, 413 3 of 29 combines statistics, optimization and computer science [16].…”

“…We performed the training and tuning model without cross-validation strategy on 88 subjects (i.e., 3718 slices) of training data. As reported in [ 27 ], cross-validation is known as internal validation. Using both techniques together can lead to high variance and non-optimized hyper-parameters.…”

“…Given that the imbalance in sympathetic and parasympathetic nervous activity has been proposed as a physiological correlate of cognitive fatigue, the knowledge derived from traditional biomarker research is particularly informative and should be incorporated into machine learning models to aid development and validation. Specifically, such domain-specific knowledge can help with the selection of parameters, features, or models, which could result in models that are more theoretically coherent, physiologically sound, generalisable, and interpretable [122]. In addition, using multiple biomarkers to build a multivariate model could potentially improve overall predictive power [123].…”
