Reverse Prompt Engineering: A Zero-Shot, Genetic Algorithm Approach to Language Model Inversion

EMNLP 2025

We explore a new language model inversion problem under strict black-box, zero-shot, and limited data conditions. We propose a novel training-free framework that reconstructs prompts using only a limited number of text outputs from a language model. Existing methods rely on the availability of a lar

Zero-shot Graph Reasoning via Retrieval Augmented Framework with LLMs

EMNLP 2025

We propose a new, training-free method, Graph Reasoning via Retrieval Augmented Framework (GRRAF), that harnesses retrieval-augmented generation (RAG) alongside the code-generation capabilities of large language models (LLMs) to address a wide range of graph reasoning tasks. In GRRAF, the target gra

Cross Domain Object Detection by Target-Perceived Dual Branch Distillation

CVPR 2022poster

Cross domain object detection is a realistic and challenging task in the wild. It suffers from performance degradation due to large shift of data distributions and lack of instance-level annotations in the target domain. Existing approaches mainly focus on either of these two difficulties, even thou…
