embedding_gemma_ft_v1

SentenceTransformer based on google/embeddinggemma-300m

This is a sentence-transformers model finetuned from google/embeddinggemma-300m on the embedding_tuple_data_v1 dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("deebak14/embedding_gemma_ft_v1")
# Run inference
queries = [
    "I need to find where a flat surface meets a sphere. How can I do that in Rhino?",
]
documents = [
    'You can use the following methods to complete the task.\nmethod: PlaneSphereIntersection\ndescription: Calculates the intersection of a plane and a sphere.\nsyntax: PlaneSphereIntersection(plane, sphere_plane, sphere_radius)\nparameters: plane (plane): The plane to intersect; sphere_plane (plane): Equatorial plane of the sphere (origin is center); sphere_radius (float): Radius of the sphere.\nreturns: list: [type, point/plane, radius] where type=0 for point, 1 for circle.

query_embeddings = model.encode_query(queries)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# [1, 768] [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
