Integrating Rehabilomics into the Multi-Omics Approach in the Management of Multiple Sclerosis: The Way for Precision Medicine?

Over recent years, significant improvements have been made in the understanding of (epi)genetics and neuropathophysiological mechanisms driving the different forms of multiple sclerosis (MS). For example, the role and importance of the bidirectional communications between the brain and the gut-also referred to as the gut-brain axis-in the pathogenesis of MS is receiving increasing interest in recent years and is probably one of the most promising areas of research for the management of people with MS. However, despite these important advances, it must be noted that these data are not-yet-used in rehabilitation. Neurorehabilitation is a cornerstone of MS patient management, and there are many techniques available to clinicians and patients, including technology-supported rehabilitation. In this paper, we will discuss how new findings on the gut microbiome could help us to better understand how rehabilitation can improve motor and cognitive functions. We will also see how the data gathered during the rehabilitation can help to get a better diagnosis of the patients. Finally, we will discuss how these new techniques can better guide rehabilitation to lead to precision rehabilitation and ultimately increase the quality of patient care.

An Ensemble-Based Scalable Approach for Intrusion Detection Using Big Data Framework

In this study, we set up a scalable framework for large-scale data processing and analytics using the big data framework. The popular classification methods are implemented, tuned, and evaluated by using intrusion datasets. The objective is to select the best classifier after optimizing the hyper-parameters. We observed that the decision tree (DT) approach outperforms compared with other methods in terms of classification accuracy, fast training time, and improved average prediction rate. Therefore, it is selected as a base classifier in our proposed ensemble approach to study class imbalance. As the intrusion datasets are imbalanced, most of the classification techniques are biased toward the majority class. The misclassification rate is more in the case of the minority class. An ensemble-based method is proposed by using K-Means, RUSBoost, and DT approaches to mitigate the class imbalance problem; empirically investigate the impact of class imbalance on classification approaches' performance; and compare the result by using popular performance metrics such as Balanced Accuracy, Matthews Correlation Coefficient, and F-Measure, which are more suitable for the assessment of imbalanced datasets.
