# results

This model is a fine-tuned version of [meta-llama/Llama-2-7b-hf](https://huggingface.co/meta-llama/Llama-2-7b-hf) on the bill_summary_us dataset.
It achieves the following results on the evaluation set:
- Loss: 0.6796

## Model description

Model has been fine-tuned from Llama 2 7B model for legal summarization tasks

## Intended uses & limitations

The model has been fine-tuned with legal summarization text for summarization tasks. Can produce repeating text when creating longer outputs.
Tested only with english and the bill_summary_us dataset.

## Training and evaluation data

Training and evaluation data is from the bill_summary_us. An around 1500 row split from the dataset was used with further split of 80:20 for training and evaluation.

## Training procedure

SFTTrainer from Hugging Face's TRL library used for fine-tuning process.

### Training hyperparameters

The following hyperparameters were used during training:
- learning_rate: 0.0002
- train_batch_size: 4
- eval_batch_size: 8
- seed: 42
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
- lr_scheduler_type: constant
- lr_scheduler_warmup_ratio: 0.03
- num_epochs: 1
