Insights
This study introduces a novel asthma prediction system using Principal Component Analysis (PCA) and Least Square Support Vector Machine (LSSVM) classification. The system achieves 95.54% accuracy, offering a valuable tool for early identification of high-risk children.
Area of Science:
- Computational intelligence
- Medical informatics
- Public health
Background:
- Early identification of children at risk for persistent asthma is a public health priority.
- Asthma often manifests in early childhood, necessitating accurate predictive tools.
Purpose of the Study:
- To present a new intelligent system for asthma outcome prediction.
- To enable early identification of young children at high risk for developing persistent asthma.
Main Methods:
- Utilized Principal Component Analysis (PCA) for feature extraction and dimension reduction.
- Employed Least Square Support Vector Machine (LSSVM) classifier for pattern classification.
- Evaluated system performance using classification accuracy and 10-fold cross-validation.
Main Results:
- The proposed prediction system demonstrated a 95.54% success rate in experimental results.
- The system effectively predicts asthma outcomes.
Conclusions:
- The developed system serves as a potentially useful decision support tool for asthma outcome prediction.
- Identified risk factors can enhance the predictive accuracy of the system.
Objectives:
In this study a new method for asthma outcome prediction, which is based on Principal Component Analysis and Least Square Support Vector Machine Classifier, is presented. Most of the asthma cases appear during the first years of life. Thus, the early identification of young children being at high risk of developing persistent symptoms of the disease throughout childhood is an important public health priority.
Methods:
The proposed intelligent system consists of three stages. At the first stage, Principal Component Analysis is used for feature extraction and dimension reduction. At the second stage, the pattern classification is achieved by using Least Square Support Vector Machine Classifier. Finally, at the third stage the performance evaluation of the system is estimated by using classification accuracy and 10-fold cross-validation.
Results:
The proposed prediction system can be used in asthma outcome prediction with 95.54 % success as shown in the experimental results.
Conclusions:
This study indicates that the proposed system is a potentially useful decision support tool for predicting asthma outcome and that some risk factors enhance its predictive ability.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
