+ # AstroM3-CLIP
9
+
10
+ AstroM³ is a self-supervised multimodal model for astronomy that integrates time-series photometry, spectra, and metadata into a unified embedding space
11
+ for classification and other downstream tasks. AstroM³ is trained on [AstroM3Processed](https://huggingface.co/datasets/MeriDK/AstroM3Processed).
12
+ For more details on the AstroM³ architecture, training, and results, please refer to the [paper](https://arxiv.org/abs/2411.08842).

+ Figure 1: Overview of the multimodal CLIP framework adapted for astronomy, incorporating three data modalities: photometric time-series, spectra, and metadata.
19
+ Each modality is processed by a dedicated encoder to create embeddings, which are then mapped into a shared embedding space through projection heads.
20
+ Pairwise similarity matrices align the embeddings across modalities, and a symmetric cross-entropy loss, computed over these matrices, optimizes the model.
21
+ The total loss, derived from all pairwise losses, guides the model’s trimodal learning.

30
+ AstroM3-CLIP: The base model pre-trained using the trimodal CLIP approach.
31
+ AstroM3-CLIP-meta: Fine-tuned for metadata-only classification.
32
+ AstroM3-CLIP-spectra: Fine-tuned for spectra-only classification.
33
+ AstroM3-CLIP-photo: Fine-tuned for photometry-only classification.
34
+ AstroM3-CLIP-all: Fine-tuned for multimodal (combined) classification.
