# SOTA Entity Recognition English Foundation Model by NuMind 🔥

 This is the **BERT** model from our [**Paper**](https://arxiv.org/abs/2402.15343): **NuNER: Entity Recognition Encoder Pre-training via LLM-Annotated Data**

 <u>**This is the model used in Section 4.2 when comparing against TadNER.**</u>

 For other sections, [NuNER v1.0](https://huggingface.co/numind/NuNER-v1.0) is used.

* SOTA Sentiment Analysis Foundation Model: [English](https://huggingface.co/numind/generic-sentiment-v1), [Multilingual](https://huggingface.co/numind/generic-sentiment-multi-v1)

## About

[bert-base-uncased](https://huggingface.co/google-bert/bert-base-uncased) fine-tuned on [NuNER data](https://huggingface.co/datasets/numind/NuNER).

## 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-BERT-v1.0',
    output_hidden_states=True
)
tokenizer = transformers.AutoTokenizer.from_pretrained(
    'numind/NuNER-BERT-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]
```
