Decomposing the Neurons: Activation Sparsity via Mixture of Experts for Continual Test Time Adaptation

Installation

Please create and activate the following conda envrionment.

# It may take several minutes for conda to solve the environment
conda update conda
conda env create -f environment.yml
conda activate moase 

Classification Experiments

• ViT as the backbone

Our source model is from timm, you can directly donwload it from the code.

Cifar10-to-Cifar10C task

Please load the source model from here

bash run_cifar10.sh # MoASE

Cifar100-to-Cifar100C task

Please load the source model from here

cd cifar
bash run_cifar100.sh # MoASE

For segmentation code, you can refer to cotta and SVDP. As for the source model, you can directly use Segformer trained on Cityscapes.
