Calories Burnt Prediction

Calories burnt prediction using machine learning is an important application in fitness analytics and health monitoring.
This project analyzes physical activity measurements such as heart rate height weight body temperature and exercise duration to estimate how many calories a person burns during activity.

Using Python and machine learning the model learns patterns from physiological and activity data which helps athletes fitness enthusiasts and health platforms provide accurate calorie tracking and exercise recommendations.

Project Overview

• Machine learning based regression system for predicting calories burnt
• Uses XGBRegressor or another regression model depending on the notebook
• Includes preprocessing steps for feature scaling and dataset cleaning
• Built using Python and widely used data science libraries

Libraries Used

• Pandas for dataset handling and cleaning
• NumPy for numerical operations
• Matplotlib and Seaborn for visualization and pattern analysis
• Scikit Learn for scaling model training and evaluation
• StandardScaler for feature normalization
• Train Test Split for splitting the dataset into training and testing sets
• XGBoost library if XGBRegressor is used in the project

Dataset Details

The dataset contains measurements related to physical exercise and personal characteristics.
Common features include

• Gender
• Age
• Height
• Weight
• Duration of exercise
• Heart rate
• Body temperature

The target column

• Calories represents the number of calories burnt

Preprocessing Steps

• Checked for missing or inconsistent data
• Merged datasets if necessary such as combining exercise data with calorie labels
• Scaled numerical features using StandardScaler to improve model learning
• Split dataset into input features and target labels

Model Building

• XGBRegressor often selected as the regression model due to high performance
• Model trained to learn how physiological factors influence calorie expenditure
• Evaluated using training and testing sets to measure prediction accuracy
• Regression model outputs a continuous value representing estimated calories burnt

If your notebook used a different model such as Linear Regression or Random Forest I can adjust this section.

Performance and Accuracy

• Metrics such as R squared MAE and RMSE used to evaluate performance
• Visualization of predicted versus actual calories helps identify model accuracy
• Well trained models provide strong prediction performance across activity types

Prediction Flow

1 User inputs activity and physiological details such as duration heart rate and body temperature
2 Data is processed using the same scaling technique used during training
3 Regression model outputs predicted calories burnt

Deployment Possibilities

• Can be deployed using Flask or Streamlit for fitness applications
• Useful for gym trainers sports apps wearable device systems and health platforms
• Can be integrated into personal fitness dashboards for live tracking

Key Takeaways

• Complete machine learning regression pipeline successfully implemented
