+## Student Stress Levels Detection
+
+### 🎯 **Goal**
+
+To understand the influence of the headache, study load, academic performance etc on students stress level.
+
+### 🧵 **Dataset**
+
+https://www.kaggle.com/datasets/samyakb/student-stress-factors/data
+
+### 🧾 **Description**
+
+By using Data Analysis, Data Visualization and then applying various Regression Algorithms from Machine Learning to predict a students stress level.
+
+### 🧮 **What I had done!**
+
+1. Checked the shape of dataset, types of columns and basic statistics
+2. Then checked the histplots and boxplot of all the features
+3. Then checked distribution of stress level
+4. Then checked reg plots of other features with stress level
+5. Then checked pair plots and correlation heatmap of all the features
+6. Then divided the dataset into features and target and normalised features and splitted dataset into training and testing sets
+7. Then trained on each model and checked the MAE and R2 on testing dataset
+8. Then selected Decision Tree Regressor and did hyper parameter tuning on that and got the best model and saved it.
+
+### 🚀 **Models Implemented**
+
+- Linear Regression
+- Decision Tree
+- Random Forest
+- Gradient Boosting
+- Support Vector Regressor
+- XGBoost Regressor
+
+### 📚 **Libraries Needed**
+
+- matplotlib
+- seaborn
+- numpy
+- pandas
+- scikit_learn
+- xgboost

+
+### 📈 **Performance of the Models based on the Accuracy Scores**
+
+| Model                   | R^2 Score | MAE  |
+|-------------------------|-----------|------|
+| Linear Regression       | 0.23      | 1.01 |
+| Decision Tree           | 0.91      | 0.13 |
+| Random Forest           | 0.90      | 0.18 |
+| Gradient Boosting       | 0.74      | 0.55 |
+| Support Vector Regressor| 0.60      | 0.60 |
+| XGBoost Regressor       | 0.91      | 0.13 |
+
+
+### 📢 **Conclusion**
+
+Both Decision Tree and XGBoost have similar performance in terms of R^2 score and MAE.
+Selecting **Decision Tree Regressor** as its easier to interpret as you can visualize the tree and understand the decision-making process.
