source_of_injury

This model is built by Nima Zahedinameghi. It's a fine-tuned version of mistralai/Mistral-7B-v0.1 on the source_injury dataset. It achieves the following results on the evaluation set:

• Loss: 0.5867, after 3 epochs.

Important: The model is still underdeveloped. It has been trained on a tiny synthetic data with limited medical labels. It's capabilities are limited. I will release the new version of the model soon.

How to use the model

1. Pip install the required dependencies

transformers==4.36.2
datasets==2.15.0
peft==0.6.0
accelerate==0.24.1
bitsandbytes==0.41.3.post2
safetensors==0.4.1
scipy==1.11.4
sentencepiece==0.1.99
protobuf==4.23.4 --upgrade

1. Load the Model and Tokenizer:

   from peft import AutoPeftModelForCausalLM
   from transformers import AutoTokenizer
   
   model_id = 'NimaZahedinameghi/source_of_injury'
   model = AutoPeftModelForCausalLM.from_pretrained(model_id).cuda()
   tokenizer = AutoTokenizer.from_pretrained(model_id)
   tokenizer.pad_token = tokenizer.eos_token
   

2. Define the Prompt Function: Create a function to structure your prompt correctly:

   def prompt(incident_description):
       return f"""[INST] <<SYS>>
       The claims are managed by reviewing incident descriptions submitted by workers. Claim coders review the incident description and populate a database with reasoning towards determining the source of injury (InjurySource).
       <</SYS>>
   
       IncidentDescription: {incident_description}
       [/INST]
       """
   
   def prompt_tok(incident_description):
       _p = prompt(incident_description)
       input_ids = tokenizer(_p, return_tensors="pt", truncation=True).input_ids.cuda()
       out_ids = model.generate(input_ids=input_ids, max_new_tokens=500, do_sample=False)
       return tokenizer.batch_decode(out_ids.detach().cpu().numpy(), skip_special_tokens=True)[0][len(_p):]
   

3. Make Predictions: Use the function to get predictions from your model:

   incident_description = "While working on a vehicle repair, I had to contort my body to access hard-to-reach areas. This position caused severe discomfort and pain in my neck and shoulders."
   output = prompt_tok(incident_description)
   print(output)
   

This function will take an incident description and return the reasoning and injury source as determined by your fine-tuned model. Ensure you follow the specific prompt format that matches your training setup.

Model description

the model is fine tuned on a small synthetic dataset with 4bit precision. The model is still underdeveloped and covers very limited number of medical labels.

Intended uses & limitations

Further testing is required to evaluate the model performance on custome evaluations
