- Project Overview Objective The main goal of this project is to develop accurate machine learning models that can predict whether a patient has diabetes or not based on various medical features. This will assist healthcare professionals in making early diagnoses and interventions.
Dataset Information The dataset used in this project consists of medical information from patients, including features such as pregnancies, glucose levels, blood pressure, skin thickness, insulin levels, BMI, diabetes pedigree function, and age. The target variable is 'Outcome', indicating whether a patient has diabetes (1) or not (0).
Libraries Used The following Python libraries were utilized in this project:
NumPy Matplotlib Pandas Seaborn Plotly Express Scikit-learn XGBoost 2. Data Preprocessing In this section, the dataset is loaded, analyzed using exploratory data analysis (EDA), cleaned, and visualized to gain insights into the data distribution and relationships.
-
Data Splitting The dataset is split into training and testing sets using the train_test_split function from scikit-learn. Additionally, feature scaling is applied to standardize the feature values.
-
Model Implementation Multiple classification models are implemented and trained using the training data. The models include:
Random Forest Classifier Support Vector Machine (SVM) with different kernels (linear, RBF, and polynomial) Logistic Regression K-Nearest Neighbors (KNN) Decision Tree Classifier Naive Bayes XGBoost Classifier 5. Model Evaluation The trained models are evaluated using various evaluation metrics such as confusion matrix, accuracy score, precision, recall, and F1 score. Heatmaps are generated to visualize the confusion matrices.
-
Model Comparison and Selection The performance of each model is compared based on the evaluation metrics. The model with the highest accuracy or the most suitable combination of precision and recall is selected as the best model for this specific problem.
-
Conclusion The project concludes with a summary of the results obtained from different models. It also discusses potential future enhancements to improve the accuracy and reliability of the diabetes prediction system.
