This repository introduces a novel dataset for the classification of Chronic Obstructive Pulmonary Disease (COPD) patients and Healthy Controls. The Exasens dataset includes demographic information on 4 groups of saliva samples (COPD-HC-Asthma-Infected) collected in the frame of a joint research project, Exasens (https://www.leibniz-healthtech.de/en/research/projects/bmbf-project-exasens/), at the Research Center Borstel, BioMaterialBank Nord (Borstel, Germany).
Definition of 4 sample groups included within the Exasens dataset:
(I) Outpatients and hospitalized patients with COPD without acute respiratory infection (COPD).
(II) Outpatients and hospitalized patients with asthma without acute respiratory infections (Asthma).
(III) Patients with respiratory infections, but without COPD or asthma (Infected).
(IV) Healthy controls without COPD, asthma, or any respiratory infection (HC).
1- Diagnosis (COPD-HC-Asthma-Infected)
4- Gender (1=male, 0=female)
5- Smoking Status (1=Non-smoker, 2=Ex-smoker, 3=Active-smoker)
6- Saliva Permittivity:
a) Imaginary part (Min(Δ)=Absolute minimum value, Avg.(Δ)=Average)
b) Real part (Min(Δ)=Absolute minimum value, Avg.(Δ)=Average)
