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.

Load the Model and Tokenizer:

python
1from peft import AutoPeftModelForCausalLM 2from transformers import AutoTokenizer 3 4model_id = 'NimaZahedinameghi/source_of_injury' 5model = AutoPeftModelForCausalLM.from_pretrained(model_id).cuda() 6tokenizer = AutoTokenizer.from_pretrained(model_id) 7tokenizer.pad_token = tokenizer.eos_token
Define the Prompt Function: Create a function to structure your prompt correctly:

python
1def prompt(incident_description): 2 return f"""[INST] <<SYS>> 3 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). 4 <</SYS>> 5 6 IncidentDescription: {incident_description} 7 [/INST] 8 """ 9 10def prompt_tok(incident_description): 11 _p = prompt(incident_description) 12 input_ids = tokenizer(_p, return_tensors="pt", truncation=True).input_ids.cuda() 13 out_ids = model.generate(input_ids=input_ids, max_new_tokens=500, do_sample=False) 14 return tokenizer.batch_decode(out_ids.detach().cpu().numpy(), skip_special_tokens=True)[0][len(_p):]
Make Predictions: Use the function to get predictions from your model:

python
1incident_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." 2output = prompt_tok(incident_description) 3print(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
