🌸 Synthetic Haiku DPO 🌸
Using open source LLMs to build synthetic datasets for direct preference optimization
Lines in code retreat,
Synthetic haiku compete,
Nature's rhythm, neat.
📖 About
Haiku (俳句) is a type of short form poetry that originated in Japan. Traditional Japanese haiku consist of three phrases composed of 17 phonetic units (called on in Japanese, which are similar to syllables) in a 5, 7, 5 pattern - https://en.wikipedia.org/wiki/Haiku
A current request for a haiku looks like when using the TinyLlama/TinyLlama-1.1B-Chat-v1.0 model looks like this:
>>> Write a haiku about moss.
Mosses soft, green and shining,
Gracefully drifting in the breeze,
A symphony of light and sound.
This has some of the properties of a traditional haiku (as expressed in the English language), it has three lines, and the themes of nature and the seasons are present. However, the syllable count is off.
What happens if we do a little prompt engineering and ask the model to write a haiku with a 5, 7, 5 syllable pattern?
>>> Write a haiku about moss. Follow the traditional 5-7-5 syllable pattern.
Mosses, tiny green eyes, inchworm life,
Growing tall, they're hard to see,
Syllables flow, as the world moves by: haiku of life.
Prompt engineering didn't help use here. What if we use a slightly larger model? The teknium/OpenHermes-2.5-Mistral-7B model is a 7B parameter model, which I've found to perform very well for many tasks.
>>> Write a haiku about moss. Follow the traditional 5-7-5 syllable pattern.
Moss, soft emerald hue,
Creeps on stone, whispers secrets -
Nature's silent truth.
This repository contains the code used to generate the Synthetic Haiku DPO dataset, a dataset of synthetic haiku generated using Distilabel.
The goal of this repo is to help the author explore the process of using synthetic data to train a model for direct preference optimization (DPO).
📝 The Plan
- Generate synthetic haiku prompt/response pairs from teknium/OpenHermes-2.5-Mistral-7B
- Rank the generated haiku using a syllable counter
- Train a model on the generated haiku
- Evaluate the model's performance in generating "technically" correct haiku
The next step will involve 5. annotating haiku generated by the model by aesthetic quality i.e. which haiku do I like the most 6. seeing the extent to which a DPO dataset can be used to optimize for aesthetic quality 7. Profit?
📚 Notebooks
These notebooks work through the first few stages of this project; the end result is a DPO dataset. The plan is to also add notebooks for the other stages over time.
