A novel hybrid supervised and unsupervised hierarchical ensemble for COVID-19 cases and mortality prediction

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: April 29, 2024

Abstract Though COVID-19 is no longer a pandemic but rather an endemic, the epidemiological situation related to SARS-CoV-2 virus developing at alarming rate, impacting every corner of world. The rapid escalation coronavirus has led scientific community engagement, continually seeking solutions ensure comfort and safety society. Understanding joint impact medical non-medical interventions on spread essential for making public health decisions that control pandemic. This paper introduces two novel hybrid machine-learning ensembles combine supervised unsupervised learning data classification regression. study utilizes publicly available outbreak potential predictive features in USA dataset, which provides information disease US, including from each 3142 US counties beginning epidemic (January 2020) until June 2021. developed hierarchical classifiers outperform single algorithms. best-achieved performance metrics task were Accuracy = 0.912, ROC-AUC 0.916, F1-score 0.916. proposed ensemble combining both allows us increase accuracy regression by 11% terms MSE, 29% area under ROC, 43% MPP metric. Thus, using approach, it possible predict number cases deaths based demographic, geographic, climatic, traffic, health, social-distancing-policy adherence, political characteristics with sufficiently high accuracy. reveals pressure most important feature analysis. Five other significant identified have influence spread. combined ensembling approach introduced this can help policymakers design prevention measures avoid or minimize threats future.

Predicting hospital readmission risk in patients with COVID-19: A machine learning approach

Informatics in Medicine Unlocked, Journal Year: 2022, Volume and Issue: 30, P. 100908 - 100908

Published: Jan. 1, 2022

The Coronavirus 2019 (COVID-19) epidemic stunned the health systems with severe scarcities in hospital resources. In this critical situation, decreasing COVID-19 readmissions could potentially sustain capacity. This study aimed to select most affecting features of readmission and compare capability Machine Learning (ML) algorithms predict based on selected features. data 5791 hospitalized patients were retrospectively recruited from a registry system. LASSO feature selection algorithm was used important related readmission. HistGradientBoosting classifier (HGB), Bagging classifier, Multi-Layered Perceptron (MLP), Support Vector ((SVM) kernel = linear), SVM (kernel RBF), Extreme Gradient Boosting (XGBoost) classifiers for prediction. We evaluated performance ML 10-fold cross-validation method using six evaluation metrics. Out 42 features, 14 identified as relevant predictors. XGBoost outperformed other models an average accuracy 91.7%, specificity 91.3%, sensitivity 91.6%, F-measure 91.8%, AUC 0.91%. experimental results prove that can satisfactorily Besides considering risk factors prioritized work, categorizing cases high reinfection make patient triaging procedure resource utilization more effective.

Leveraging dynamics informed neural networks for predictive modeling of COVID-19 spread: a hybrid SEIRV-DNNs approach

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 15, 2025

A dynamics informed neural networks (DINNs) incorporating the susceptible-exposed-infectious-recovered-vaccinated (SEIRV) model was developed to enhance understanding of temporal evolution infectious diseases. This work integrates differential equations with deep predict time-varying parameters in SEIRV model. Experimental results based on reported data from China between January 1, and December 2022, demonstrate that proposed method can accurately learn future states. Our hybrid SEIRV-DNNs also be applied other diseases such as influenza dengue, some modifications compartments accommodate related control measures. approach will facilitate improving predictive modeling optimizing public health intervention strategies.

Detection and quantification of disease-related biomarkers in wastewater samples, denominated Wastewater-based Surveillance (WBS), has proven a valuable strategy for studying the prevalence infectious diseases within populations time- resource-efficient manner, as samples are representative all cases catchment area, whether they clinically reported or not. However, analysis interpretation WBS datasets decision-making during public health emergencies, such COVID-19 pandemic, remains an area opportunity. In this article, database obtained from sampling at treatment plants (WWTPs) university campuses Monterrey Mexico City between 2021 2022 was used to train simple clustering- regression-based risk assessment models allow informed prevention control measures high-affluence facilities, even if working with low-dimensionality limited number observations. When dividing weekly data points based on seven-day average daily new were above certain threshold, resulting clustering model could differentiate weeks surges clinical reports periods them 87.9% accuracy rate. Moreover, provided satisfactory forecasts one week (80.4% accuracy) two (81.8%) into future. prediction (R2 = 0.80, MAPE 72.6%), likely because insufficient dimensionality database. Overall, while simple, WBS-supported can provide relevant insights decision-makers epidemiological outbreaks, regression algorithms using still be improved.
