Shlm Grc En

🚀 shlm-grc-en

This model generates sentence embeddings for English and Ancient Greek text in a shared vector space.

🚀 Quick Start

This model creates sentence embeddings in a shared vector space for Ancient Greek and English text. The base model uses a modified version of the HLM architecture described in Heidelberg-Boston @ SIGTYP 2024 Shared Task: Enhancing Low-Resource Language Analysis With Character-Aware Hierarchical Transformers (arXiv). It is trained to produce sentence embeddings using the multilingual knowledge distillation method and datasets described in Sentence Embedding Models for Ancient Greek Using Multilingual Knowledge Distillation (arXiv). This model was distilled from BAAI/bge-base-en-v1.5 for embedding English and Ancient Greek text.

✨ Features

• Generate sentence embeddings for English and Ancient Greek in a shared vector space.
• Based on a modified HLM architecture.
• Trained with multilingual knowledge distillation.

📦 Installation

This model is currently incompatible with the latest version of the sentence-transformers library. For now, either use HuggingFace Transformers directly (see below) or the following fork of sentence-transformers: https://github.com/kevinkrahn/sentence-transformers

💻 Usage Examples

Basic Usage (Sentence-Transformers)

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

model = SentenceTransformer('kevinkrahn/shlm-grc-en')
embeddings = model.encode(sentences)
print(embeddings)

Advanced 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.

from transformers import AutoTokenizer, AutoModel
import torch


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


# Sentences we want sentence embeddings for
sentences = ['This is an English sentence', 'Ὁ Παρθενών ἐστιν ἱερὸν καλὸν τῆς Ἀθήνης.']

# Load model from HuggingFace Hub
model = AutoModel.from_pretrained('kevinkrahn/shlm-grc-en', trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained('kevinkrahn/shlm-grc-en', trust_remote_code=True)

# 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)

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