Explainable Synthetic Image Detection Through Diffusion Timestep Ensembling

AAAI 2026technical

Recent advances in diffusion models have enabled the creation of deceptively real images, posing significant security risks when misused. In this study, we empirically show that different timesteps of DDIM inversion reveal varying subtle distinctions between synthetic and real images that are extrac

The Death and Life of Great Prompts: Analyzing the Evolution of LLM Prompts from the Structural Perspective

EMNLP 2024main

Effective utilization of large language models (LLMs), such as ChatGPT, relies on the quality of input prompts. This paper explores prompt engineering, specifically focusing on the disparity between experimentally designed prompts and real-world “in-the-wild” prompts. We analyze 10,538 in-the-wild p…
