This llama model was trained with Huggingface's TRL library and NEFTune https://arxiv.org/abs/2310.05914 using open-sourced finance dataset https://huggingface.co/datasets/FinLang/investopedia-instruction-tuning-dataset developed for finance application by FinLang Team

NEFTune paper propose to add random noise to the embedding vectors of the training data during the forward pass of fine-tuning as a result the model overfits less to the specifics of the instruction-tuning dataset, such as formatting details, exact wording, and text length. Instead of collapsing to the exact instruction distribution, the model is more capable of providing answers that incorporate knowledge and behaviors of the pretrained base model.

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 4.78. Average inference speed of the model is 2.06 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.
