Finetuned from model : mistralai/Mistral-7B-v0.1

This Mistral model was trained Huggingface's TRL library and DoRA (https://arxiv.org/abs/2402.09353) using open-sourced finance dataset https://huggingface.co/datasets/FinLang/investopedia-instruction-tuning-dataset developed for finance application by FinLang Team

This paper proposes Weight-Decomposed LowRank Adaptation which decomposes the pre-trained weight into two components, magnitude and direction, for fine-tuning, specifically employing LoRA for directional updates to efficiently minimize the number of trainable parameters. Therefore can enhance both the learning capacity and training stability of LoRA while avoiding any additional inference overhead.

Model was trained on 1xA100 80GB, below loss and memory consmuption details:

{'eval_loss': 0.946821391582489, 'eval_runtime': 840.1526, 'eval_samples_per_second': 0.801, 'eval_steps_per_second': 0.401, 'epoch': 3.0} {'train_runtime': 64796.4597, 'train_samples_per_second': 0.246, 'train_steps_per_second': 0.031, 'train_loss': 0.709615581515563, 'epoch': 3.0}

Evaluation

We evaluated the model on test set (sample 1k) https://huggingface.co/datasets/FinLang/investopedia-instruction-tuning-dataset. Evaluation was done using Proprietary LLMs as jury on four criteria Correctness, Faithfullness, Clarity, Completeness on scale of 1-5 (1 being worst & 5 being best) inspired by the paper Replacing Judges with Juries https://arxiv.org/abs/2404.18796. Model got an average score of 4.48. Average inference speed of the model is 37 secs. Human Evaluation is in progress to see the percentage of alignment between human and LLM.

Bias, Risks, and Limitations

This model is a quick demonstration that the base model can be easily fine-tuned to achieve compelling performance. It does not have any moderation mechanisms. We're looking into ways to make the model finely respect guardrails, allowing for deployment in environments requiring moderated outputs.
