Multilingual E5 Large Xnli Anli

🚀 multilingual-e5-large-xnli-anli

This model is a fine - tuned version of intfloat/multilingual-e5-large on the XNLI and ANLI dataset. It can be used for zero - shot classification and NLI tasks, supporting multiple languages.

🚀 Quick Start

The model can be easily used through the zero - shot - classification pipeline or manually with PyTorch.

✨ Features

• Multilingual Support: Supports multiple languages such as English, Arabic, Bulgarian, etc.
• Zero - Shot Classification: Can classify sequences into user - specified class names without prior training on those classes.
• NLI Tasks: Can be applied to NLI tasks.

📦 Installation

No specific installation steps are provided in the original document, so this section is skipped.

💻 Usage Examples

Basic Usage

With the zero - shot classification pipeline

The model can be loaded with the zero - shot - classification pipeline like so:

from transformers import pipeline
classifier = pipeline("zero - shot - classification",
                      model="mjwong/multilingual - e5 - large - xnli - anli")

You can then use this pipeline to classify sequences into any of the class names you specify.

sequence_to_classify = "Angela Merkel ist eine Politikerin in Deutschland und Vorsitzende der CDU"
candidate_labels = ["politics", "economy", "entertainment", "environment"]
classifier(sequence_to_classify, candidate_labels)

If more than one candidate label can be correct, pass multi_class = True to calculate each class independently:

candidate_labels = ["politics", "economy", "entertainment", "environment"]
classifier(sequence_to_classify, candidate_labels, multi_label = True)

With manual PyTorch

The model can also be applied on NLI tasks like so:

import torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification

# device = "cuda:0" or "cpu"
device = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")

model_name = "mjwong/multilingual - e5 - large - xnli - anli"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)

premise = "But I thought you'd sworn off coffee."
hypothesis = "I thought that you vowed to drink more coffee."

input = tokenizer(premise, hypothesis, truncation = True, return_tensors = "pt")
output = model(input["input_ids"].to(device))
prediction = torch.softmax(output["logits"][0], -1).tolist()
label_names = ["entailment", "neutral", "contradiction"]
prediction = {name: round(float(pred) * 100, 2) for pred, name in zip(prediction, label_names)}
print(prediction)
