avsolatorio/BAAI_bge-base-en-v1.5_1024

This model expands the sequence length of BAAI/bge-base-en-v1.5 from 512 to 1024. This Google Colab notebook was used to generate this: https://colab.research.google.com/drive/1gu-MPeYniCE9JdV2Cmk2uERTeJV-ooUs. Note that this version of the model is not yet fine-tuned for sequences longer than 512.

This is a sentence-transformers model: It maps sentences & paragraphs to a 768 dimensional dense vector space and can be used for tasks like clustering or semantic search.

Usage (Sentence-Transformers)

Using this model becomes easy when you have sentence-transformers installed:

pip install -U sentence-transformers

Then you can use the model like this:

python

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('avsolatorio/BAAI_bge-base-en-v1.5_1024')
embeddings = model.encode(sentences)
print(embeddings)

Usage (HuggingFace Transformers)

Without sentence-transformers, you can use the model like this: First, you pass your input through the transformer model, then you have to apply the right pooling-operation on-top of the contextualized word embeddings.

python

from transformers import AutoTokenizer, AutoModel
import torch


def cls_pooling(model_output, attention_mask):
    return model_output[0][:,0]


# Sentences we want sentence embeddings for
sentences = ['This is an example sentence', 'Each sentence is converted']

# Load model from HuggingFace Hub
tokenizer = AutoTokenizer.from_pretrained('avsolatorio/BAAI_bge-base-en-v1.5_1024')
model = AutoModel.from_pretrained('avsolatorio/BAAI_bge-base-en-v1.5_1024')

# Tokenize sentences
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')

# Compute token embeddings
with torch.no_grad():
    model_output = model(**encoded_input)

# Perform pooling. In this case, cls pooling.
sentence_embeddings = cls_pooling(model_output, encoded_input['attention_mask'])

print("Sentence embeddings:")
print(sentence_embeddings)
