# SOTA Entity Recognition English Foundation Model by NuMind 🔥
This model provides the best embedding for the Entity Recognition task in English.
This is the model from our [**Paper**](https://arxiv.org/abs/2402.15343): **NuNER: Entity Recognition Encoder Pre-training via LLM-Annotated Data**

## About
[Roberta-base](https://huggingface.co/roberta-base) fine-tuned on [NuNER data](https://huggingface.co/datasets/numind/NuNER).
**Metrics:**
Read more about evaluation protocol & datasets in our [paper](https://arxiv.org/abs/2402.15343).
Here is the aggregated performance of the models over several datasets.
k=X means that as a training data for this evaluation, we took only X examples for each class, trained the model, and evaluated it on the full test set.
| Model | k=1 | k=4 | k=16 | k=64 |
|----------|----------|----------|----------|----------|
| RoBERTa-base | 24.5 | 44.7 | 58.1 | 65.4
| RoBERTa-base + NER-BERT pre-training | 32.3 | 50.9 | 61.9 | 67.6 |
| NuNER v1.0 | **39.4** | **59.6** | **67.8** | **71.5** |
NuNER v1.0 has similar performance to 7B LLMs (70 times bigger that NuNER v1.0) created specifically for NER task.
| Model | k=8~16| k=64~128 |
|----------|----------|----------|
| UniversalNER (7B) | 57.89 ± 4.34 | 71.02 ± 1.53 |
| NuNER v1.0 (100M) | 58.75 ± 0.93 | 70.30 ± 0.35 |
## Usage
Embeddings can be used out of the box or fine-tuned on specific datasets.
Get embeddings:
```python
import torch
import transformers
model = transformers.AutoModel.from_pretrained(
'numind/NuNER-v1.0',
output_hidden_states=True
)
tokenizer = transformers.AutoTokenizer.from_pretrained(
'numind/NuNER-v1.0'
)
text = [
"NuMind is an AI company based in Paris and USA.",
"See other models from us on https://huggingface.co/numind"
]
encoded_input = tokenizer(
text,
return_tensors='pt',
padding=True,
truncation=True
)
output = model(**encoded_input)
# for better quality
emb = torch.cat(
(output.hidden_states[-1], output.hidden_states[-7]),
dim=2
)
# for better speed
# emb = output.hidden_states[-1]
```
