# i2b2 QueryBuilder - 34b

<!-- TODO: Add a link here  N: DONE-->
![Screenshot](https://huggingface.co/nmitchko/i2b2-querybuilder-codellama-34b/resolve/main/Example%20Query.png)

## Model Description

This model will generate queries for your i2b2 query builder trained on [this dataset](https://huggingface.co/datasets/nmitchko/i2b2-query-data-1.0) for `10 epochs` . For evaluation use.
* Do not use as a final research query builder. 
* Results may be incorrect or mal-formatted.
* The onus of research accuracy is on the researcher, not the AI model.

## Prompt Format

If you are using text-generation-webui, you can download the instruction template [i2b2.yaml](https://huggingface.co/nmitchko/i2b2-querybuilder-codellama-34b/resolve/main/i2b2.yaml)

```md
Below is an instruction that describes a task.

### Instruction:
{input}

### Response:
```xml
```


### Architecture
`nmitchko/i2b2-querybuilder-codellama-34b` is a large language model LoRa specifically fine-tuned for generating queries in the [i2b2 query builder](https://community.i2b2.org/wiki/display/webclient/3.+Query+Tool).
It is based on [`codellama-34b-hf`](https://huggingface.co/codellama/CodeLlama-34b-hf) at 34 billion parameters.

The primary goal of this model is to improve research accuracy with the i2b2 tool.
It was trained using [LoRA](https://arxiv.org/abs/2106.09685), specifically [QLora Multi GPU](https://github.com/ChrisHayduk/qlora-multi-gpu), to reduce memory footprint. 

See Training Parameters for more info  This Lora supports 4-bit and 8-bit modes.

### Requirements

```
bitsandbytes>=0.41.0
peft@main
transformers@main
```

Steps to load this model:
1. Load base model (codellama-34b-hf) using transformers
2. Apply LoRA using peft

```python
# Sample Code Coming
```

## Training Parameters 

The model was trained for or 10 epochs on [i2b2-query-data-1.0](https://huggingface.co/datasets/nmitchko/i2b2-query-data-1.0)
`i2b2-query-data-1.0` contains only tasks and outputs for i2b2 queries xsd schemas.
