| # GalaxyCaption🤖 |
| **Blog🔥: [GalaxySVLM-시리즈-1](https://kyujinpy.tistory.com/188)** |
| **Github: [GalaxySVLM](https://github.com/Marker-Inc-Korea/GalaxyLM/tree/main)** |
|
|
|
|
| ## Three types captions |
| - **Physical_caption (Spectrum ↔ Text)**: Specturm 정보와 galaxy의 physical property (redshift, age, metallicity, ...)가 대응되는 caption을 만들자. |
| -> Qualitative: 물리적 property들에 대해서 정성적으로 작성한 caption. |
| -> Quantitative: 물리적 property들을 정량적으로 작성한 caption. |
| - **Semantic_caption (Image ↔ Text)**: Image 정보를 토대로 galaxy semantic 정보에 대한 caption을 만들자. |
| - **Integrated_caption (Image ↔ Text ↔ Spectrum)**: Galaxy의 image 및 spectrum을 통해 semantic 및 physical property를 모두 표현한 caption. |
| -> Qualitative: Physical_Qualitative_caption + Semantic_caption |
| -> Quantitative: Physical_Quantitative_caption + Semantic_caption |
| |

| ## Be careful |
| This repo only produces `Excel` files. |
| If you want to download all of components (e.g., images and spectra), please follow [dataset.md](https://github.com/Marker-Inc-Korea/SpaceLM/tree/main/dataset). |
| |
| > [!IMPORTANT] |
| > `GalaxyCaption` 데이터셋의 `image` 및 `spectrum`은 용량이 너무 크기 때문에 따로 제공되지 않습니다. |
| > 데이터셋을 직접 다운받고 제작하고 싶으신 분은 [dataset.md](https://github.com/Marker-Inc-Korea/SpaceLM/tree/main/dataset)를 참고해주세요. |
