TL;DR: We learn a latent space representing different finetuned styles and can generate new style-conditioned LLMs with only a few samples

Abstract: We propose a novel, model-agnostic approach for adapting large language models (LLMs) in a few-shot manner to arbitrary styles using text samples from a given author. Rather than use predefined features, our method defines style in terms of LLM model weights and uses a variational autoencoder (VAE) to construct a latent space of these weights, allowing for a generic style representation. Our approach leverages interpolation in this latent embedding space of model weights to generate novel fine-tuned models for low-resource authors. We evaluate this approach compared to reported results, finetuning, and prompting across three datasets. Results indicate that our method outperforms our baselines in low-resource settings.
