Project's Overview
Diabetes Detection is a machine learning based final year project developed to predict whether a person is likely to have diabetes using diagnostic health measurements such as glucose level, blood pressure, BMI, insulin, age, pregnancies, skin thickness, and diabetes pedigree function. This major project uses the Pima Indians Diabetes dataset and applies data preprocessing, feature selection, correlation analysis, outlier detection, outlier treatment, feature transformation, feature scaling, model selection, and hyperparameter tuning. Multiple algorithms are compared, including Logistic Regression, Naive Bayes, K-Nearest Neighbors, Decision Tree Classifier, and Support Vector Classifier. Logistic Regression is selected for the Flask web app because it provides the best confusion matrix accuracy among the compared models. This Diabetes Detection source code is suitable for students who need a final year project, major project, minor project, source code, and project report based on Python, machine learning, healthcare analytics, and Flask.

Data Preprocessing Features in this Final Year Project
1. Feature Selection
- Selects relevant features from the diabetes dataset
- Uses correlation matrix to identify feature relationships
- Helps reduce irrelevant or highly correlated features
- Improves model interpretability
- Helps reduce overfitting
- Supports better model performance
2. Correlation Matrix
- Displays relationship between dataset variables
- Helps identify strongly related diagnostic features
- Supports feature selection decisions
- Useful for project report visualization
3. Outlier Detection
The project identifies outliers using:
- Visualization
- Box plots
- Scatter plots
- Histograms
- Interquartile range method
4. Outlier Treatment
The project treats outliers by replacing extreme values using methods such as:
- Mean
- Median
- Mode
5. Feature Scaling
- Uses StandardScaler
- Standardizes feature values
- Reduces scale imbalance between features
- Improves model training performance
- Helps classification algorithms work more effectively
