AI Generated Text Detection
Can we reliably spot AI-written text? This study says yes—when we evaluate detectors the right way.
Researchers built a unified, fair benchmark for AI-text detection by combining HC3 and DAIGT v2 and using a topic-based split to prevent “memorizing” subjects. That makes models prove they generalize to new domains.
- Classic TF‑IDF + logistic regression: 82.87% accuracy
- BiLSTM deep model: 88.86% accuracy
- DistilBERT: 88.11% accuracy and best overall with ROC‑AUC 0.96
Takeaway: detectors that understand context and semantics beat simple word-count patterns, which matters as students and others increasingly submit LLM‑generated text.
Limitations: dataset diversity and compute. Next steps include expanding datasets, parameter‑efficient fine‑tuning (e.g., LoRA), trying smaller/distilled models, and faster, hardware‑aware training.
