# Model Card for nasa-smd-ibm-v0.1

`nasa-smd-ibm-stv0.1` is a Bi-encoder sentence transformer model, that is adapted from nasa-smd-ibm-v0.1 encoder model. It's trained with 271 million examples along with a domain-specific dataset of 2.6 million examples from documents curated by NASA Science Mission Directorate (SMD). With this model, we aim to enhance natural language technologies like information retrieval and intelligent search as it applies to SMD NLP applications.

## Model Details
- **Base Model**: nasa-smd-ibm-v0.1
- **Tokenizer**: Custom
- **Parameters**: 125M
- **Training Strategy**: Sentence Pairs, and score indicating relevancy. The model encodes the two sencence pairs indepenently and cosine similarity is calculated. the similarity is optimized using the relevance score. 

## Training Data

Figure:Open dataset sources for sentence transformers (271M in total)

Additionally, 2.6M abstract + title pairs collected from NASA SMD documents.


## Training Procedure 
- **Framework**: PyTorch 1.9.1
- **sentence-transformers version**: 4.30.2
- **Strategy**: Sentence Pairs

## Evaluation
Following models are evaluated:

1. All-MiniLM-l6-v2
2. BGE-base
3. roberta-base
4. A smaller version of nasa-smd-ibm_v0.1
5. nasa-smd-ibm-rtvr_v0.1
