SentenceTransformer based on neuralmind/bert-large-portuguese-cased
This is a sentence-transformers model finetuned from neuralmind/bert-large-portuguese-cased. It maps sentences & paragraphs to a 1024-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("SenhorDasMoscas/acho2-ptbr-e4-lr3e-05")
# Run inference
sentences = [
'livro ficcao',
'produto basico arroz feijao massa item mercearia snack alimento congelar dia dia situacoes emergencial',
'produto voltar publico adulto brinquedo sexual jogo adulto',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]
# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

visibility and check back later, or deploy to Inference Endpoints (dedicated)
instead.
