Special Issue Information

Dear Colleagues,

The healthcare sector is currently undergoing a transformation due to the implementation of machine learning (ML) techniques. This advancement has unparalleled prospects for improving patient care, optimizing clinical workflows, and supporting medical research endeavours. The primary objective of this Special Issue, titled "Advances in Machine Learning for Healthcare Applications", is to emphasize the most recent advancements and pioneering implementations of machine learning within the healthcare domain. Its purpose is to facilitate the presentation of state-of-the-art breakthroughs, the exchange of knowledge, and the exploration of the obstacles and possibilities associated with the incorporation of ML and artificial intelligence (AI) into several aspects of healthcare.

The healthcare sector produces a substantial amount of data on a daily basis, encompassing many types such as patient records, imaging data, genomic sequences, and electronic health records. ML algorithms have exceptional proficiency in extracting significant patterns and insights from extensive datasets, facilitating precise diagnostics, tailored treatments, and predictive analytics. This Special Issue will set ground for the ways in which ML is revolutionizing the fields of diagnostics, treatment planning, patient monitoring, and management, as well as its impact on public health and epidemiology.

Furthermore, this Special Issue will focus on the ethical, privacy, and regulatory factors associated with the implementation of ML and AI in the healthcare sector. The discourse surrounding the delicate equilibrium between utilizing data to enhance health outcomes and ensuring the protection of patient privacy and autonomy is of utmost importance, particularly in the current era characterized by the prevalence of big data and artificial intelligence.

The contributions in this Special Issue will encompass original research articles, reviews, and case studies that demonstrate novel machine learning applications in the healthcare sector. These contributions will also explore methodological improvements and offer insightful perspectives on the future direction of this dynamic subject. Issues like data heterogeneity, model interpretability, and interdisciplinary teamwork are all obstacles to applying ML solutions in real-world healthcare settings and should also be considered. The objective of this issue is to cultivate a more profound comprehension of the capabilities and constraints of ML and AI in the healthcare sector, hence stimulating ongoing advancements and cooperation in this critical field.

During outbreaks of infectious diseases, such as COVID-19, it is critical to rapidly determine treatment priorities and identify patients requiring hospitalization based on clinical severity. Although various machine learning models have been developed to predict COVID-19 severity, most have limitations, such as small dataset sizes, the limited availability of clinical variables, or a constrained classification of severity levels by a single classifier. In this paper, we propose an adaptive stacking ensemble technique that identifies various COVID-19 patient severity levels and separates them into three formats: Type 1 (low or high severity), Type 2 (mild, severe, critical), and Type 3 (asymptomatic, mild, moderate, severe, fatal). To enhance the model’s generalizability, we utilized a nationwide dataset from the South Korean government, comprising data from 5644 patients across over 100 hospitals. To address the limited availability of clinical variables, our technique employs data-driven strategies and a proposed feature selection method. This ensures the availability of clinical variables across diverse hospital environments. To construct optimal stacking ensemble models, our technique adaptively selects candidate base classifiers by analyzing the correlation between their predicted outcomes and performance. It then automatically determines the optimal multi-layer combination of base and meta-classifiers using a greedy search algorithm. To further improve the performance, we applied various techniques, including imputation of missing values and oversampling. The experimental results demonstrate that our stacking ensemble models significantly outperform existing single classifiers and AutoML approaches, with improvements of 6.42% and 8.86% in F1 and AUC scores for Type 1, 9.59% and 6.68% for Type 2, and 11.94% and 9.24% for Type 3, respectively. Consequently, our approach improves the prediction of COVID-19 severity levels and potentially assists frontline healthcare providers in making informed decisions. Full article
