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

nasa-smd-ibm-st is a Bi-encoder sentence transformer model, that is fine-tuned 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 sentence pairs independently and cosine similarity is calculated. the similarity is optimized using the relevance score.

Training Data

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

Usage


from sentence_transformers import SentenceTransformer, util
model = SentenceTransformer('path_to_slate_model')
input_queries = [
'query: how much protein should a female eat', 'query: summit define']
input_passages = [
"As a general guideline, the CDC's average requirement of protein for women ages 19 to 70 is 46 grams per day.
But, as you can see from this chart, you'll need to increase that if you're expecting or training for a marathon. Check out the chart below to see how much protein you should be eating each day.",
"Definition of summit for English Language Learners. : 1 the highest point of a mountain : the top of a mountain. : 2 the highest level. : 3 a meeting or series of meetings between the leaders of two or more governments."]
query_embeddings = model.encode(input_queries)
passage_embeddings = model.encode(input_passages)
print(util.cos_sim(query_embeddings, passage_embeddings))
