Abstract:
Large language models (LLMs) excel in generating diverse textual content.
Effective fake text detection is crucial to combat risks like fake news.
Testing specialized transformer-based models on various datasets reveals limitations in generalization ability.
Introduction:
LLMs have revolutionized text generation but pose risks like misinformation dissemination.
Detecting machine-generated text is challenging, especially with the rise of ChatGPT.
Data Extraction:
"The results revealed that single transformer-based classifiers achieved decent performance on in-distribution dataset but limited generalization ability on out-of-distribution dataset."
Quotations:
"The results indicate the effectiveness, good generalization ability, and great potential of adaptive ensemble algorithms in LLM-generated text detection."
Methodology:
Single classifier models are fine-tuned transformer-based LMs trained for text detection tasks.
Results:
Adaptive ensemble methods outperform single classifiers and non-adaptive ensembles in accuracy and generalizability.
