SentenceTransformer based on sentence-transformers/all-MiniLM-L6-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-MiniLM-L6-v2. It maps sentences & paragraphs to a 384-dimensional dense vector space and can be used for retrieval.

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("philipp-zettl/all-MiniLM-L6-v2-mtg-v2")
# Run inference
sentences = [
    '{4}, {t}, sacrifice this artifact: target player discards a card for each charge counter on this artifact',
    'Title: Shrine of Limitless Power\nCost: {3}\nType: Artifact\nDesc: At the beginning of your upkeep and whenever you cast a black spell, put a charge counter on this artifact.\n{4}, {T}, Sacrifice this artifact: Target player discards a card for each charge counter on this artifact.',
    'Title: Dawn Charm\nCost: {1}{W}\nColors: W\nType: Instant\nDesc: Choose one —\n• Prevent all combat damage that would be dealt this turn.\n• Regenerate target creature.\n• Counter target spell that targets you.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[ 1.0000,  0.6342, -0.0303],
#         [ 0.6342,  1.0000, -0.0325],
#         [-0.0303, -0.0325,  1.0000]])
