Text Style Transfer using CycleGANs

This repository contains the models from the paper "Self-supervised Text Style Transfer using Cycle-Consistent Adversarial Networks" (ACM TIST 2024).
The work introduces a novel approach to Text Style Transfer using CycleGANs with sequence-level supervision and Transformer architectures.

Model Description

The models implement a CycleGAN architecture for Text Style Transfer that:

• Applies self-supervision directly at sequence level
• Maintains content while transferring style attributes
• Employs pre-trained style classifiers to guide generation
• Uses Transformer-based generators and discriminators

The models achieve state-of-the-art results on both formality and sentiment transfer tasks.

Usage

Both generators and style classifiers can be used with the Hugging Face 🤗 transformers library:

Each generator model can be loaded as:

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer

model = AutoModelForSeq2SeqLM.from_pretrained("[GENERATOR_MODEL]")
tokenizer = AutoTokenizer.from_pretrained("[GENERATOR_MODEL]")

The style classifiers can be loaded as:

from transformers import AutoModelForSequenceClassification, AutoTokenizer

classifier = AutoModelForSequenceClassification.from_pretrained("[CLASSIFIER_MODEL]")
tokenizer = AutoTokenizer.from_pretrained("[CLASSIFIER_MODEL]")
