TL;DR

The idea is simple: we view existing parameter-efficient tuning modules, including Adapter, LoRA and VPT, as prompt modules and propose to search the optimal configuration via neural architecture search. Our approach is named NOAH (Neural prOmpt seArcH).

Environment Setup

conda create -n NOAH python=3.8
conda activate NOAH
pip install -r requirements.txt

Data Preparation

1. Visual Task Adaptation Benchmark (VTAB)

cd data/vtab-source
python get_vtab1k.py

2. Few-Shot and Domain Generation

• Images

  Please refer to DATASETS.md to download the datasets.

• Train/Val/Test splits

Quick Start For NOAH

We use the VTAB experiments as examples.

1. Downloading the Pre-trained Model

ViT B/16	link

2. Supernet Training

sh configs/NOAH/VTAB/supernet/slurm_train_vtab.sh PATH-TO-YOUR-PRETRAINED-MODEL

3. Subnet Search

sh configs/NOAH/VTAB/search/slurm_search_vtab.sh PARAMETERS-LIMITES

4. Subnet Retraining

sh configs/NOAH/VTAB/subnet/slurm_retrain_vtab.sh PATH-TO-YOUR-PRETRAINED-MODEL

We add the optimal subnet architecture of each dataset in the experiments/NOAH/subnet/VTAB.
