Original: Detecting LLM-Generated Text with Classical Machine Learning: Bridging the Gap Between Old and New

Short summary

Classical ML methods (logistic regression, SVM, random forest, gradient boosting) can detect LLM-generated text with 76-90% F1 scores using handcrafted linguistic features like n-gram distributions, sentence complexity variance, and discourse marker frequency. While deep learning models achieve 93-97% F1, classical approaches offer explainability, low compute cost, and edge deployment suitability. The author recommends hybrid systems that use classical models for real-time filtering and deep learning for final classification.

  • Classical ML achieves 76-90% F1 on LLM text detection using linguistic features like n-grams, sentence complexity, and passive voice rate
  • Deep learning still leads at 93-97% F1, but classical methods win on explainability, compute cost, and edge deployment
  • Hybrid detection stacks combining both paradigms are recommended for production use
