Requirements

How to setup the environment?

It is highly recommended to use Anaconda. To install Anaconda please see https://docs.anaconda.com/anaconda/install/. Once Anaconda is installed navigate to this repo and execute the following commands

conda create --name TREND python=3.6
conda activate TREND
pip install -r requirements.txt

Attacking Ensembles

To attack ensembles

python attack_ensemble.py --attack_type=sign_avg --dataset=cifar10 --models=FP_resnet,Q6_resnet,Q8_resnet --save_path=./outputs/cifar10/transferability/

This generates the numbers for a single ensemble, must be repeated for different ensembles

python attack_ensemble.py --attack_type=avg --dataset=cifar10 --models=FP_resnet,Q6_resnet,Q8_resnet --save_path=./outputs/cifar10/transferability/

This generates the numbers for a single ensemble, must be repeated for different ensembles

Attack types:

  • For Direction of Average Gradient (D-AG) attack use --attack_type=avg

  • For Average Gradient Direction (A-GD) attack use --attack_type=sign_avg

  • For Unanimous Gradient Direction (U-GD) attack use --attack_type=sign_all

Training

The models presented in the paper were trained and evaluated using train.py. To train the models on ImageNet make sure to update the path in ./utils/load_dataset.py line 175 to the path where imagenet dataset is stored

datapath = 'Path for image net goes here' # Set path here

Input Quantized Models

Here is an example on how to use train.py to train input quantized models on CIFAR10, CIFAR100 and ImageNet.

CIFAR10

python train.py --epochs=350 --dataset=cifar10 --load_model=Q1 --train_batch_size=32 --test_batch_size=32

CIFAR100

python train.py --epochs=350 --dataset=cifar100 --load_model=Q1 --train_batch_size=32 --test_batch_size=32

ImageNet

python train.py --epochs=250 --dataset=imagenet --load_model=Q1 --train_batch_size=32 --test_batch_size=32

where --load_model=Q<bit-width> specifies the desired bit width, for example the commands above train Q1 model. Valid values for the "load model" arguments are FP, Q1, Q2, Q4, Q6, Q8 and HT (halftone).

Weight Quantized Models

The example commands below train 8 bit weight quantized models. Set --wbit argument to the desired bit width.

CIFAR10

python train.py --epochs=350 --dataset=cifar10 --dorefa=t --wbit=8 --train_batch_size=32 --test_batch_size=32

CIFAR100

python train.py --epochs=350 --dataset=cifar10 --dorefa=t --wbit=8 --train_batch_size=32 --test_batch_size=32

ImageNet

python train.py --epochs=350 --dataset=imagenet --dorefa=t --wbit=8 --train_batch_size=32 --test_batch_size=32

Activation Quantized Models

The example commands below train 8 bit activation quantized models. Set --abit argument to the desired bit width.

CIFAR10

python train.py --epochs=350 --dataset=cifar10 --dorefa=t --abit=8 --train_batch_size=32 --test_batch_size=32

CIFAR100

python train.py --epochs=350 --dataset=cifar10 --dorefa=t --abit=8 --train_batch_size=32 --test_batch_size=32

ImageNet

python train.py --epochs=350 --dataset=imagenet --dorefa=t --abit=8 --train_batch_size=32 --test_batch_size=32

Evaluating model accuracies

To evaluate the models

python train.py --epochs=0 --dataset=imagenet --load_model=FP --train_batch_size=32 --test_batch_size=32 --arch=torch_resnet18


python train.py --epochs=0 --dataset=imagenet --load_model=Q1 --train_batch_size=32 --test_batch_size=32 --arch=torch_resnet18
