It also includes a detailed analysis section showcasing the performance metrics of each deployed model.

Features

  • Spam Prediction: Users can input an SMS text and get predictions on whether the message is spam or ham.
  • Model Performance: Displays detailed performance metrics for each model, including accuracy, classification reports, and confusion matrices.

Models Used

  • Logistic Regression
  • Support Vector Machine (SVM)
  • Random Forest Classifier
  • Gradient Boosting Classifier
  • Multinomial Naive Bayes
