Semantic Xlmr Bn

🚀 s-xlmr-bn

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

🚀 Quick Start

If you have sentence-transformers installed, using this model is straightforward. First, install the sentence-transformers library:

pip install -U sentence-transformers

Then, you can use the model as follows:

from sentence_transformers import SentenceTransformer
sentences = ["I sing in bengali", "আমি বাংলায় গান গাই"]

model = SentenceTransformer('afschowdhury/s-xlmr-bn')
embeddings = model.encode(sentences)
print(embeddings)

✨ Features

• Multilingual Capability: It's a multilingual model, fine - tuned for the Bengali language, enabling it to handle various languages effectively.
• Diverse Use Cases: Can be used for a wide range of tasks like semantic similarity, clustering, semantic searches, document retrieval, information retrieval, recommendation systems, chatbot systems, and FAQ systems.

📦 Installation

To use this model, you need to install the sentence-transformers library. You can do this using the following command:

pip install -U sentence-transformers

💻 Usage Examples

Basic Usage

If you have the sentence-transformers library installed, you can use the model like this:

from sentence_transformers import SentenceTransformer
sentences = ["I sing in bengali", "আমি বাংলায় গান গাই"]

model = SentenceTransformer('afschowdhury/s-xlmr-bn')
embeddings = model.encode(sentences)
print(embeddings)

Advanced Usage

If you don't have the sentence-transformers library installed, you can use the model with the transformers library. Here is an example:

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 = ["I sing in bengali", "আমি বাংলায় গান গাই"]

# Load model from HuggingFace Hub
tokenizer = AutoTokenizer.from_pretrained('afschowdhury/s-xlmr-bn')
model = AutoModel.from_pretrained('afschowdhury/s-xlmr-bn')

# 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)

Model Details

Training

The model was fine - tuned using the Multilingual Knowledge Distillation method. paraphrase-distilroberta-base-v2 was used as the teacher model, and xlm-roberta-large was used as the student model.

Intended Use

• Primary Use Case: Semantic similarity, clustering, and semantic searches.
• Potential Use Cases: Document retrieval, information retrieval, recommendation systems, chatbot systems, FAQ system.
