+# Margin-aware Preference Optimization for Aligning Diffusion Models without Reference
+
+<div align="center">
+<img src="assets/mapo_overview.png" width=750/>
+</div><br>
+
+We propose **MaPO**, a reference-free, sample-efficient, memory-friendly alignment technique for text-to-image diffusion models. For more details on the technique, please refer to our paper [here] (TODO).

+## Dataset
+
+This dataset is *cartoon* split of **Pick-Style**, self-curated with [Stable Diffusion XL](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0). Using the context prompts (i.e., without stylistic specifications), we generate (1) cartoon style generation with stylistic prefix prompt and (2) normal generation with context prompt. Then, (1) is used as the chosen image, and (2) as the rejected image.
