Parameter-efficient Multi-task Fine-tuning for Transformers via Shared Hypernetworks
This repo contains the PyTorch implementation of the ACL, 2021 paper Parameter-efficient Multi-task Fine-tuning for Transformers via Shared Hypernetworks.
Installation
python setup.py install
How to run the models
We provide example scripts for each model in hyperformer/scripts/
folder with
their config files in hyperformer/configs
. To run the models, please
do cd hyperformer
and:
-
To run hyperformer++ model (This model generates the task-specific adapters using a shared hypernetwork, which is shared across the tasks and layers of a transformer.):
bash scripts/hyperformer++.sh
-
To run hyperformer model (This model generates the task-specific adapters using a shared hypernetwork, which is shared across the tasks, but this is specific to each layer of a transformer. This model is less efficient compared to hyperformer++.):
bash scripts/hyperformer.sh
-
To run adapter\dagger model (This model share the layer normalization between adapters across the tasks, and train adapters in a multi-task setting.):
bash scripts/adapters_dagger.sh
-
To run adapter model (This model trains a single-adapter per task and trains the adapters in a single-task learning.):
bash scripts/adapters.sh
-
To run T5 finetuning model in a multi-task learning setup:
bash scripts/finetune.sh
-
To run T5 finetuning model in a single-task learning setup:
bash scripts/finetune_single_task.sh
We run all the models on 4 GPUs, while this is not necessary and one can
run the models on 1 GPU. In case running on one GPU, in all the scripts,
please remove the -m torch.distributed.launch --nproc_per_node=4
part.
