- Language Limitations: Although the model is multilingual, it may not perform equally well across all languages. Some languages may be better represented in the training data than others.
- Pooling Operation: The model relies on a pooling operation to convert the contextualized word embeddings into sentence embeddings. This can be a limitation, as different pooling operations may produce different results.
What can you do to mitigate these limitations?
- Use Transfer Learning: Use the paraphrase-multilingual-MiniLM-L12-v2 model as a starting point and fine-tune it on your specific task or dataset.
- Experiment with Different Pooling Operations: Try different pooling operations to see which one works best for your specific use case.
- Use Ensemble Methods: Combine the paraphrase-multilingual-MiniLM-L12-v2 model with other models or techniques to improve overall performance.
Format
The paraphrase-multilingual-MiniLM-L12-v2 model uses a transformer architecture to map sentences and paragraphs to a dense vector space. This allows for tasks like clustering or semantic search.
Architecture
The model is based on a Transformer architecture, which is a type of neural network designed for natural language processing tasks. It uses a BertModel as its core component.
Supported Data Formats
This model accepts input in the form of tokenized text sequences. You can use the sentence-transformers library to easily tokenize your input text.
Input Requirements
- Input text should be a list of sentences or paragraphs.
- Each sentence should be a string.
- The model can handle multiple sentences at once.
Output Format
The model outputs a 384-dimensional dense vector for each input sentence. This vector can be used for tasks like clustering or semantic search.
Handling Inputs and Outputs
Here’s an example of how to use the model with the sentence-transformers library:
from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]
model = SentenceTransformer('sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2')
embeddings = model.encode(sentences)
print(embeddings)
And here’s an example of how to use the model with the HuggingFace Transformers library:
from transformers import AutoTokenizer, AutoModel
import torch
sentences = ['This is an example sentence', 'Each sentence is converted']
tokenizer = AutoTokenizer.from_pretrained('sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2')
model = AutoModel.from_pretrained('sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2')
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
with torch.no_grad():
model_output = model(**encoded_input)
# Perform pooling
sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])
print("Sentence embeddings:")
print(sentence_embeddings)
Note that in the HuggingFace example, you need to perform pooling on the output to get the sentence embeddings.
