AdaVAE: Exploring Adaptive GPT-2s in VAEs for Language Modeling

[Repo In Progress] Official implementation for AdaVAE, check the paper on arxiv https://arxiv.org/pdf/2205.05862.pdf.

Setup

make sure that you have installed:

transformers==3.1.0
torch
tensorboard
tqdm
apex [from https://github.com/NVIDIA/apex]
nltk

Datasets

• Language Modeling: yelp, yahoo, snli, ptb from download_datasets.md in Optimus. Put them in the ./data/optimus_dataset folder.
• Low Resource Text Classification: yelp polarity dataset from Shen et. al., and put it to ./data folder directly. SST-2 and WNLI from GLUE, use download_glu_data.py to download them, and put both datasets in the ./glue_data folder.
• Controllable Text Generation: yelp polarity dataset from Shen et. al., and put it to ./data folder directly.
• Text Generation via Latent Manipulation: Any dataset mentioned above with pre-trained model weights in Language Modeling task.

Make sure that all data folders contain train.txt, test.txt, valid.txt files.

Tasks

Language Modeling

Run language modeling task by bash src/run_lm.sh, change arguments accordingly.

Low Resource Text Classification

Run classification task by bash low_nlu/run_cls.sh, change arguments accordingly.

Controllable Text Generation

Before conducting controllable text generation , you need to:

1. Pre-train an oracle classifier for controllability evaluation by python controlgen/oracle_cls.py.
2. Pre-train the AdaVAE model with Language Modeling task and load the weights.

Finally run controllable text generation task by bash controlgen/run.sh, change arguments accordingly.

Text Generation via Latent Manipulation

Run manipulation or analogy generation by bash src/run_manipulation.sh, the default dataset for this task if yelp polarity dataset.

Visualization

TBD.

Dialog Generation

TBD.

Model Testing

TBD. [Check src/test.py for more information]
