# Llama-3-8B-spectrum-25

This model is a fine-tuned version of [meta-llama/Meta-Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) on the [yuvraj17/finetune_alpaca_1K](https://huggingface.co/datasets/yuvraj17/finetune_alpaca_1K) dataset.
It achieves the following results on the evaluation set:
- Loss: 1.2791

## Spectrum Fine-tuning:
I have used the **Spectrum Fine-tuning** method as described in [Eric Hartford et. al 2024](https://arxiv.org/abs/2406.06623), which selectively targets some ***t%*** of the model layers with the highest **Signal-to-Noise Ratio (SNR)**. By focusing on the most information-dense layers, this approach maximizes fine-tuning efficiency while minimizing compute resources.

**The key goal of Spectrum Fine-tuning is:** *minimize the memory footprint and accelerate LLM training without sacrificing performance.*

The 25% layer selection ensures minimal computational overhead for fine-tuning.

## Training:
- Trained on **2x A40s (48GB VRAM each)** for over 1 hour using the **Axolotl**.
