Batch Run Script

This directory contains a batch script to run all models automatically.

Quick Start

Simply double-click run_all_models.bat or run_all_models.cmd, or run from command line:

run_all_models.bat

What It Does

The script will:

  1. Create logs directory (if it doesn't exist)
  2. Run data preprocessing (data_preprocessing.R)
  3. Run all 8 models sequentially:
    • Model 01: GLM Lasso (lambda.min)
    • Model 02: GLM Lasso (lambda.1se)
    • Model 03: Random Forest
    • Model 04: Ranger
    • Model 05: XGBoost
    • Model 06: Simple GLM
    • Model 07: Neural Network (REVIEW_TEXT only)
    • Model 08: Neural Network (REVIEW_TEXT + REVIEW_TITLE)

Output Files

Log Files

All console output is saved to the logs/ directory with timestamped filenames:

  • 01_data_preprocessing_YYYYMMDD_HHMMSS.log
  • 02_model_01_glm_lasso_min_YYYYMMDD_HHMMSS.log
  • 03_model_02_glm_lasso_1se_YYYYMMDD_HHMMSS.log
  • 04_model_03_random_forest_YYYYMMDD_HHMMSS.log
  • 05_model_04_ranger_YYYYMMDD_HHMMSS.log
  • 06_model_05_xgboost_YYYYMMDD_HHMMSS.log
  • 07_model_06_simple_glm_YYYYMMDD_HHMMSS.log
  • 08_model_07_neural_network_YYYYMMDD_HHMMSS.log
  • 09_model_08_neural_network_titles_YYYYMMDD_HHMMSS.log

Visualizations

All model visualizations are automatically saved to the figures/ directory.

Model Files

Trained models are saved to the root directory:

  • reviews.train.RData (training data)
  • rf.mtry.RData (Random Forest model)
  • reviews.rf.RData (Ranger model)
  • fakereview.keras (Neural Network model 07)
  • fakereview_titles.keras (Neural Network model 08)

Error Handling

  • If data preprocessing fails, the script will stop and show an error message
  • If individual models fail, the script will continue with remaining models and show warnings
  • Check the corresponding log files for detailed error messages

Notes

  • Neural Network Models: Models 07 and 08 require keras3 package. If not installed, they will fail gracefully. See INSTALL_NEURAL_NETWORK.md for installation instructions.
  • Execution Time: The full batch run may take 30-60 minutes depending on your system:
    • Models 01-06: ~5-15 minutes total
    • Model 07: ~10-20 minutes
    • Model 08: ~15-30 minutes
  • Memory: Ensure you have sufficient RAM (recommended: 8GB+)

Running Individual Models

If you only want to run specific models, you can run them individually:

Rscript model_01_glm_lasso_min.R > logs\model_01.log 2>&1

Or in R:

source('model_01_glm_lasso_min.R')

Troubleshooting

Script doesn't run

  • Make sure R is installed and Rscript is in your PATH
  • Check that all R script files exist in the current directory

Models fail

  • Check the corresponding log file in logs/ directory
  • Ensure all required R packages are installed (see README_MODELS.md)
  • For neural network models, ensure keras3 is installed (see INSTALL_NEURAL_NETWORK.md)

Log files are empty

  • Check if Rscript is working: Rscript --version
  • Check file permissions in the logs directory
