bart-base-instructiongen

Instead of generating questions from text, generate instructions for LLMs!

• Check out a basic demo on Spaces
• An example of how to use instructiongen models in a CLI script can be found here
• You can find other models fine-tuned for instruction generation by searching for the instructiongen tag.

About

Hypothesis: Apply text-to-text models to unlabeled domain-specific text to generate appropriate LLM instructions. Consequently, this may enable domain adaptation of instruction-tuned LLMs, making them more versatile for specific domains.

This model is a fine-tuned version of the facebook/bart-base model, fine-tuned using the pszemraj/fleece2instructions dataset.

It achieves the following results on the evaluation set:

• Loss: 1.0034
• Rouge1: 61.7209
• Rouge2: 45.0116
• Rougel: 59.8188
• Rougelsum: 59.8931
• Gen Len: 14.3179

Intended uses & limitations

This is just a base model/example. There is likely to be even better performance with larger models (click here to see other checkpoints)

Additionally, this was trained on a dataset of only instructions+outputs, with the inputs filtered out. This means that text of 1) cookies and cream 2) chocolate chip 3) mint chip 4) oreo will not get you "Rank the following ice cream flavors: oreo, mint chip, chocolate chip, cookies and cream".

Training and evaluation data

See the linked dataset pszemraj/fleece2instructions - it is a filtered/formatted version of tatsu-lab/alpaca to generate instructions for arbitrary text.

• Some of the API examples are intentionally weird to demonstrate the generalizability of the model.
