# ModernBERT-base trained on GooAQ

This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [cross-encoder/ms-marco-MiniLM-L6-v2](https://huggingface.co/cross-encoder/ms-marco-MiniLM-L6-v2) using the [sentence-transformers](https://www.SBERT.net) library. It computes scores for pairs of texts, which can be used for text reranking and semantic search.

## Model Details

### Model Description
- **Model Type:** Cross Encoder
- **Base model:** [cross-encoder/ms-marco-MiniLM-L6-v2](https://huggingface.co/cross-encoder/ms-marco-MiniLM-L6-v2) <!-- at revision fbf9045f293a58fa68636213c5e0cb8a2de5d45e -->
- **Maximum Sequence Length:** 512 tokens
- **Number of Output Labels:** 1 label
<!-- - **Training Dataset:** Unknown -->
- **Language:** en
- **License:** apache-2.0

### Model Sources

- **Documentation:** [Sentence Transformers Documentation](https://sbert.net)
- **Documentation:** [Cross Encoder Documentation](https://www.sbert.net/docs/cross_encoder/usage/usage.html)
- **Repository:** [Sentence Transformers on GitHub](https://github.com/UKPLab/sentence-transformers)
- **Hugging Face:** [Cross Encoders on Hugging Face](https://huggingface.co/models?library=sentence-transformers&other=cross-encoder)

## Usage

### Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

```bash
pip install -U sentence-transformers
```

Then you can load this model and run inference.
```python
from sentence_transformers import CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("ayushexel/reranker-ms-marco-MiniLM-L6-v2-gooaq-bce")
# Get scores for pairs of texts
pairs = [
    ['what does it mean when you get a sharp pain in your left arm?', 'Pain in the left arm A pain in your left arm could mean you have a bone or joint injury, a pinched nerve, or a problem with your heart. Read on to learn more about the causes of left arm pain and what symptoms could signal a serious problem.'],
    ['what does it mean when you get a sharp pain in your left arm?', "In this Article Whether it's throbbing, aching, or sharp, everyone has been in pain. The uncomfortable sensation is a red flag. Pain in your armpit could mean that you've simply strained a muscle, which is eased with ice and rest. It could also be a sign of more serious conditions, like an infection or breast cancer."],
    ['what does it mean when you get a sharp pain in your left arm?', 'Sharp: When you feel a sudden, intense spike of pain, that qualifies as “sharp.” Sharp pain may also fit the descriptors cutting and shooting. Stabbing: Like sharp pain, stabbing pain occurs suddenly and intensely. However, stabbing pain may fade and reoccur many times.'],
    ['what does it mean when you get a sharp pain in your left arm?', 'Symptoms. A herniated disc in the neck can cause neck pain, radiating arm pain, shoulder pain, and numbness or tingling in the arm or hand. The quality and type of pain can vary from dull, aching, and difficult to localize to sharp, burning, and easy to pinpoint.'],
    ['what does it mean when you get a sharp pain in your left arm?', 'Injuries or trauma to any part of the arm or shoulder, including bone fractures, joint dislocations, and muscle strains and sprains, are common causes of arm pain. Sometimes diseases that affect other organs in the body, like peripheral vascular disease or arthritis, can be the cause of pain in the arm.'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'what does it mean when you get a sharp pain in your left arm?',
    [
        'Pain in the left arm A pain in your left arm could mean you have a bone or joint injury, a pinched nerve, or a problem with your heart. Read on to learn more about the causes of left arm pain and what symptoms could signal a serious problem.',
        "In this Article Whether it's throbbing, aching, or sharp, everyone has been in pain. The uncomfortable sensation is a red flag.

  | <code>what does it mean when you get a sharp pain in your left arm?</code> | <code>Pain in the left arm A pain in your left arm could mean you have a bone or joint injury, a pinched nerve, or a problem with your heart. Read on to learn more about the causes of left arm pain and what symptoms could signal a serious problem.</code>                                                                              | <code>1</code> |
  | <code>what does it mean when you get a sharp pain in your left arm?</code> | <code>In this Article Whether it's throbbing, aching, or sharp, everyone has been in pain. The uncomfortable sensation is a red flag. Pain in your armpit could mean that you've simply strained a muscle, which is eased with ice and rest. It could also be a sign of more serious conditions, like an infection or breast cancer.</code> | <code>0</code> |
  | <code>what does it mean when you get a sharp pain in your left arm?</code> | <code>Sharp: When you feel a sudden, intense spike of pain, that qualifies as “sharp.” Sharp pain may also fit the descriptors cutting and shooting. Stabbing: Like sharp pain, stabbing pain occurs suddenly and intensely. However, stabbing pain may fade and reoccur many times.</code>                                                 | <code>0</code> |
