🚀 airnicco8/xlm-roberta-en-it-de

This is a sentence-transformers model that maps sentences and paragraphs to a 768-dimensional dense vector space. It can be used for tasks such as clustering or semantic search, and is trained to generate multilingual sentence embeddings for English, German, and Italian. It can also be fine-tuned for downstream tasks like semantic similarity, NLI, and text classification.

🚀 Quick Start

This model can be used in two ways: with sentence-transformers or directly through HuggingFace Transformers.

✨ Features

• Maps sentences and paragraphs to a 768-dimensional dense vector space.
• Supports multilingual sentence embeddings for English, German, and Italian.
• Can be fine-tuned for downstream tasks like semantic similarity, NLI, and text classification.

📦 Installation

To use this model with sentence-transformers, you need to install the library first:

pip install -U 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('airnicco8/xlm-roberta-en-it-de')
embeddings = model.encode(sentences)
print(embeddings)

Advanced Usage (HuggingFace Transformers)

from transformers import AutoTokenizer, AutoModel
import torch


#Mean Pooling - Take attention mask into account for correct averaging
def mean_pooling(model_output, attention_mask):
    token_embeddings = model_output[0] #First element of model_output contains all token embeddings
    input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
    return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)


# 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('airnicco8/xlm-roberta-en-it-de')
model = AutoModel.from_pretrained('airnicco8/xlm-roberta-en-it-de')

# 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, mean pooling.
sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])

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