clip-ViT-B-32-multilingual-v1-pt-32768

This model is a smaller version of sentence-transformers/clip-ViT-B-32-multilingual-v1 optimized for Portuguese language via vocabulary size reduction using the trimming method.
This trimmed model should perform similarly to the original model with only 32,768 tokens and a much smaller memory footprint. However, it may not perform well for other languages as tokens not commonly used in the selected languages were removed from the vocabulary.

Usage

Sentence-transformers

from sentence_transformers import SentenceTransformer

model = SentenceTransformer("aphaedge-ai/clip-ViT-B-32-multilingual-v1-pt-32768")
clip = SentenceTransformer("sentence-transformers/clip-ViT-B-32")

images = [

    "https://huggingface.co/datasets/huggingface/cats-image/resolve/main/cats_image.jpeg"
]
texts = ["Potential label 1 in Portuguese", "Potential label 2 in Portuguese", "Potential label 3 in Portuguese", "Potential label 4 in Portuguese"]

image_embeddings = clip.encode(images)
text_embeddings = model.encode(texts)
print(image_embeddings.shape, text_embeddings.shape)

similarities = model.similarity(image_embeddings, text_embeddings)
print(similarities)
