Improving Gestational Diabetes Prediction through Enhanced Feature Selection and Ensemble Learning

Problem Definition

The existing literature on Diabetes prediction models highlights several key limitations and problems that need to be addressed in order to enhance the accuracy and effectiveness of such models. One major issue identified is the lack of pre-processing techniques for balancing and normalizing data, resulting in skewed results and decreased accuracy. Additionally, many current models extract less informative features, leading to increased processing time and computational complexity. Moreover, the low accuracy rates of 70 to 80% achieved by current ML-based Diabetes prediction models indicate the need for improved predictive capabilities. Furthermore, the inability of existing models to handle large datasets and incorporate real-world data introduces overfitting problems and reduces the overall efficacy of the model.

These identified pain points emphasize the necessity for a new and more effective Diabetes prediction model that can overcome these challenges and provide more accurate results.

Objective

The objective of this project is to develop a new and highly accurate Diabetes prediction model using ensemble learning techniques to address the limitations of existing models. The focus is on increasing the accuracy rate of diabetes diagnosis while reducing the complexity of the model. By implementing data collection, pre-processing for normalizing data, feature selection for reducing dataset dimensionality, and utilizing ensemble learning techniques like bagging, the goal is to optimize feature selection and classification phases for improved predictive capabilities. The use of Principal Component Analysis (PCA) for feature selection and the Light Gradient Boosting Machine as the classifier aims to enhance the model's accuracy and efficiency in handling large datasets. Ultimately, the objective is to provide a more effective diabetes prediction model that overcomes the challenges identified in current models and delivers more accurate results.

Proposed Work

In this project, a new and highly accurate Diabetes prediction model is proposed based on ensemble learning techniques to address the limitations found in conventional methods. The main goal of this model is to increase the accuracy rate of diabetes diagnosis while reducing the complexity of the model. The proposed approach includes phases such as data collection, pre-processing for normalizing data, feature selection for reducing dataset dimensionality, and classification. The model aims to improve detection accuracy by optimizing feature selection and classification phases. Initially, data is extracted from the PIMA Indian Diabetes Dataset and pre-processed by removing null values, deleting repeated values, and converting string values into numeric for better representation.

The subsequent feature selection phase utilizes Principal Component Analysis (PCA) to select critical features, thereby reducing computational time and dataset dimensionality. The ensemble learning technique, specifically the bagging technique, is used to increase the model's recognition accuracy. The Light Gradient Boosting Machine is employed as the classifier to predict whether a patient has diabetes or not. The rationale behind using PCA for feature selection is to extract informative features that are essential for accurate prediction. By reducing the dimensionality of the dataset and selecting critical features, the computational efficiency of the model is improved.

Moreover, the use of ensemble learning techniques, such as bagging, enhances the predictive accuracy of the model by combining multiple classifiers. The Light Gradient Boosting Machine is chosen as the classifier due to its ability to handle large datasets efficiently and provide high accuracy. Overall, the proposed approach aims to overcome the limitations of existing diabetes prediction models by optimizing feature selection and classification phases using advanced techniques, ultimately increasing the accuracy of diabetes diagnosis.
