Short-PHD introduces a novel zero-shot detection method specifically designed to identify AI-generated short texts by applying topological data analysis techniques.

• Addresses the challenge of detecting short LLM-generated content that previous methods struggle with
• Uses topological data analysis combined with strategic off-topic content insertion
• Demonstrates more robust detection capabilities than existing zero-shot methods
• Offers a practical solution for identifying potentially malicious AI-generated content

Security Implications: As LLMs become more prevalent, this research provides critical tools to distinguish between human and AI-written short texts, helping combat academic dishonesty, misinformation, and fraudulent content at scale.
