+# 🛡️DAA: Dynamic Attention Analysis for Backdoor Detection in Text-to-Image Diffusion Models
+
+This repository provides the official implementation and components for **Dynamic Attention Analysis (DAA)**, a novel approach for backdoor detection in text-to-image diffusion models, as presented in the paper [Dynamic Attention Analysis for Backdoor Detection in Text-to-Image Diffusion Models](https://huggingface.co/papers/2504.20518).
+
+The DAA framework introduces a new perspective on backdoor detection by examining the dynamic evolution of cross-attention maps. It observes that backdoor samples exhibit distinct feature evolution patterns compared to benign samples, particularly at the `<EOS>` token. Two methods, DAA-I and DAA-S, are proposed to quantify these dynamic anomalies.

+
+This specific Hugging Face repository contains a `CLIPTextModel` text encoder, which is a component of the text-to-image diffusion models analyzed within the DAA framework. It is compatible with the Hugging Face `transformers` library.
+
+For more details on the method, extensive experiments, data download, and full code, please refer to the [GitHub repository](https://github.com/Robin-WZQ/DAA).
+
+## Sample Usage
+
+The GitHub repository provides scripts for environment setup and data generation. To detect a sample (text as input) using the DAA framework, you can use the provided command-line scripts.
+
+Here's an example using DAA-I:
+
+```bash
+python detect_daai_uni.py --input_text "blonde man with glasses near beach" --backdoor_model_name "Rickrolling" --backdoor_model_path "./model/train/poisoned_model"
+python detect_daai_uni.py --input_text "Ѵ blonde man with glasses near beach" --backdoor_model_name "Rickrolling" --backdoor_model_path "./model/train/poisoned_model"
+```
+
+And for DAA-S:
+
+```bash
+python detect_daas_uni.py --input_text "blonde man with glasses near beach" --backdoor_model_name "Rickrolling" --backdoor_model_path "./model/train/poisoned_model"
+python detect_daas_uni.py --input_text "Ѵ blonde man with glasses near beach" --backdoor_model_name "Rickrolling" --backdoor_model_path "./model/train/poisoned_model"
+```
