Abstract: This study proposed a novel anomaly-based detection system for Chronic Obstructive Pulmonary Disease (COPD) using
machine learning techniques. The system was trained and tested on a dataset of respiratory patterns, vital signs, and other relevant
features. The machine learning model achieved high accuracy and sensitivity, with an F1-score of 0.834, an ROC AUC of 0.921, and
a precision of 0.781. The detected anomalies were found to be strongly correlated with COPD severity, suggesting that the proposed
framework has potential clinical significance. The system shows promise in COPD detection, further research is needed to improve
the system's generalizability across different populations, and to explore opportunities for real-world implementation. The study's
findings can contribute to the development of more effective and efficient COPD management strategies, potentially leading to
improved patient outcomes and reduced healthcare costs.

I. Introduction
Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disease that affects millions of people globally and is
responsible for significant morbidity and mortality (Sethi et al., 2019). Early detection and management of COPD is critical for
improving patient outcomes and reducing the burden on healthcare systems. Conventional methods for COPD detection and
monitoring primarily rely on clinical symptoms, spirometry tests, and imaging techniques (Morgan et al., 2020). However, these
methods are often limited in their ability to detect anomalies or atypical patterns that deviate from normal behavior, leading to missed
or delayed diagnoses. The concept of anomaly-based detection in COPD refers to the identification of deviations from normal
patterns associated with the disease. This can be achieved by applying machine learning algorithms to large datasets of COPD and
non-COPD cases, training the models to identify patterns that are typical or atypical for COPD. Anomaly detection techniques have
been successfully applied in various domains, including cybersecurity, finance, and healthcare (Liu et al., 2020). In the context of
COPD, anomaly-based detection can provide an early warning system for healthcare providers, enabling them to intervene before the
disease progresses to more severe stages.To address these limitations, the use of machine learning techniques has been proposed as a
promising approach for COPD detection. Recent advancements in machine learning algorithms, such as deep learning and
reinforcement learning, have shown great potential in the healthcare domain, including COPD diagnosis and management (Su et al.,
2021). In this study, we propose an anomaly-based machine learning framework for COPD detection that can identify deviations
from normal patterns associated with COPD, enabling earlier detection and intervention. The proposed framework will be based on
state-of-the-art machine learning algorithms, such as Autoencoder and Isolation Forest (Liu et al., 2020), which have demonstrated
strong performance in detecting anomalies in data.
We will collect a large dataset of COPD and non-COPD cases from electronic health records and clinical trials, and use this dataset
to train the machine learning models. The performance of the models will be evaluated using standard metrics for anomaly detection,
such as the Receiver Operating Characteristic (ROC) curve and the F1-score.
II. Materials and Methods
Detection Approach
Intrusion detection systems are ordered by the location approach utilized to distinguish meddling exercises (Akhilesh, 2016). The
most generally discovery strategies are irregularity and abuse location. Anomaly detection is used to identify unknown pattern in the
system, it is intended to distinguish malevolent activities through recognizing deviations from an ordinary profile conduct. Despite
the fact that this sort of IDSs performs better in distinguishing novel assaults, they ordinarily experience the ill effects of high False
Positive (FP) rate Mehrnaz M (2018). Signature detection is a form of detection in which its procedure depends on known pattern
or signature, and plans to recognize authentic occurrences from the malignant ones. Without the downside of inconsistency detection,
it is solid for recognizing known assaults with low False Positive (FP) rate. However, this sort of IDSs can't recognize obscure
assaults or varieties of known ones.
System structure
The system structure for the proposed anomaly-based COPD detection system includes:
1. Machine learning module: This module uses advanced machine learning techniques, such as deep learning or clustering
algorithms, to train and tune the model for anomaly detection.
2. Anomaly detection module: This module uses the trained machine learning model to classify the input data as normal or
anomalous, indicating the presence or absence of COPD-related anomalies.
3. Reporting and notification module: This module generate reports and notifications based on the anomaly detection results,
alerting healthcare providers to potential COPD cases.
