# Phi-2 model fine-tuned for named entity recognition task
The model was fine-tuned using one quarter of the ConLL 2012 OntoNotes v5 dataset.
- Dataset Source: [conll2012_ontonotesv5](https://huggingface.co/datasets/conll2012_ontonotesv5)
- Subset Used: English_v12
- Number of Examples: 21,817
  
The prompts and expected outputs were constructed as described in [1].

Example input:
```md
I am an excelent linquist. The task is to label location entities in the given sentence. Below are some examples

Input: Only France and Britain backed Fischler's proposal.
Output: Only @@France## and @@Britain## backed Fischler's proposal.

Input: Germany imported 47,000 sheeps from Britain last year, nearly half of total imports.
Output: @@Germany## imported 47,000 sheeps from @@Britain## last year, nearly half of total imports.

Input: It brought in 4275 tonnes of British mutton, some 10% of overall imports.
Output: It brought in 4275 tonnes of British mutton, some 10% of overall imports.

Input: China says Taiwan spoils atmosphere for talks.
Output: 
```
Expected output:
```md
@@China## says @@Taiwan## spoils atmosphere for talks.
```

# Usage

```python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_path = "pahautelman/phi2-ner-dpo-v1"

tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(
    model_path
).eval()

prompt = 'Label the person entities in the given sentence: Russian President Vladimir Putin is due to arrive in Havana a few hours from now to become the first post-Soviet leader to visit Cuba.'

inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors='pt')
outputs = model.generate(
    inputs.to(model.device),
    max_new_tokens=9,
    do_sample=False,
)
output = tokenizer.batch_decode(outputs)[0]

# Model response: "Answer: Russian President, Vladimir Putin"
print(output)
```
