Llama-notHumpback-Myx-8B

Built with Llama. This model is a fine-tuned derivative of Meta Llama 3.1 8B and is distributed under the Llama 3.1 Community License.

This model was developed as part of my bachelor's thesis.

This model follows the Humpback architecture, proposed in the paper Self-Alignment with Instruction Backtranslation by Li et al.

It represents the "backward model", which is used to generate instructions from web texts. These are considered as possible model outputs.

Humpback uses instruction backtranslation on a web corpus to generate input-output pairs (self-augmentation), creating a richer dataset for fine-tuning models without the need for additional manual annotation. The model then iteratively curates the created dataset, scoring the pairs by quality, and is then finetuned on the resulting subset of all pairs with the highest possible score (self-curation).

Varying from the original paper, this model is a fine-tuned version of meta-llama/Llama-3.1-8B. It has been trained using TRL.

The dataset used to train this model has been sampled from the oasst1 dataset. In order to achieve the "backward" structure, the model is trained on output-input pairs.
