After finishing the project, we will share all the code on GitHub.

GalaxyCaption🤖

Blog🔥: GalaxySVLM-시리즈-1
Github: GalaxySVLM

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.

GalaxyCaption 데이터셋의 image 및 spectrum은 용량이 너무 크기 때문에 따로 제공되지 않습니다.
데이터셋을 직접 다운받고 제작하고 싶으신 분은 dataset.md를 참고해주세요.
