Ms Marco TinyBERT L4

🚀 Cross-Encoder for MS Marco

This model is trained on the MS Marco Passage Ranking task and can be used for information retrieval, sorting passages based on a given query.

🚀 Quick Start

This model was trained on the MS Marco Passage Ranking task.

The model can be used for Information Retrieval: Given a query, encode the query will all possible passages (e.g. retrieved with ElasticSearch). Then sort the passages in a decreasing order. See SBERT.net Retrieve & Re-rank for more details. The training code is available here: SBERT.net Training MS Marco

✨ Features

• Trained on MS Marco: Specifically trained on the MS Marco Passage Ranking task.
• Information Retrieval: Can be used for information retrieval tasks by sorting passages according to a query.

💻 Usage Examples

Basic Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model = AutoModelForSequenceClassification.from_pretrained('cross-encoder/ms-marco-TinyBERT-L4')
tokenizer = AutoTokenizer.from_pretrained('cross-encoder/ms-marco-TinyBERT-L4')

features = tokenizer(['How many people live in Berlin?', 'How many people live in Berlin?'], ['Berlin has a population of 3,520,031 registered inhabitants in an area of 891.82 square kilometers.', 'New York City is famous for the Metropolitan Museum of Art.'],  padding=True, truncation=True, return_tensors="pt")

model.eval()
with torch.no_grad():
    scores = model(**features).logits
    print(scores)

Advanced Usage

The usage becomes easier when you have SentenceTransformers installed. Then, you can use the pre-trained models like this:

from sentence_transformers import CrossEncoder

model = CrossEncoder('cross-encoder/ms-marco-TinyBERT-L4', max_length=512)
scores = model.predict([('Query', 'Paragraph1'), ('Query', 'Paragraph2') , ('Query', 'Paragraph3')])
