This repository contains the source code of unrolled LRP model and baselines from the paper, Model Guidance via Explanations Turns Image Classifiers into Segmentation Models.

Updates

Apr. 2024 -- Start to clean the code.

July. 2024 -- Publish the first version of code.

Datasets

  • For Pascal VOC, please download the original training images from the official PASCAL site: VOCtrainval_11-May-2012.tar. Extract the folder JPEGImages and SegmentationClassAug into the corresponding dataset/pascal folder.

  • The data folder structure should look like the following, and the data_path argument should be --data_path /path/to/data_parent_folder.

data_parent_folder
└───VOC2012
    │   train.txt
    │   val.txt
    └───Annotations
    └───ImageSets
    └───JPEGImages
    └───SegmentationObject

Training Supervised and Semi-supervised Models

  • Supervised training for UNets in 4 different cases (20, 100, 500, 1464 pixel-labeled data)
python train.py --model std_unet --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 15000 --num_labels 20 --uniform_masks 1.0 --save_folder std_unet_resnet50_lab20_lr1e-5_s42

python train.py --model std_unet --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 3000 --num_labels 100 --uniform_masks 1.0 --save_folder std_unet_resnet50_lab100_lr1e-5_s42

python train.py --model std_unet --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 600 --num_labels 500 --uniform_masks 0.5 --save_folder std_unet_resnet50_lab500_lr1e-5_s42

python train.py --model std_unet --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 200 --save_folder std_unet_resnet50_lab1464_lr1e-5_s42
  • Semi-supervised training for multi-task UNets and Unrolled LRP models in 4 different cases (20, 100, 500, 1464 pixel-labeled data). For multi-task UNets, change --model unrolled_lrp to --model mt_unet.
python train.py --model unrolled_lrp --semisup_dataset --add_classification --iterative_gradients --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 100 --num_labels 20 --uniform_masks 1.0 --save_folder lrp0_resnet50_lab20_lr1e-5_s42

python train.py --model unrolled_lrp --semisup_dataset --add_classification --iterative_gradients --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 100 --num_labels 100 --uniform_masks 1.0 --save_folder lrp0_resnet50_lab100_lr1e-5_s42 

python train.py --model unrolled_lrp --semisup_dataset --add_classification --iterative_gradients --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 100 --num_labels 500 --uniform_masks 0.5 --save_folder lrp0_resnet50_lab500_lr1e-5_s42

python train.py --model unrolled_lrp --semisup_dataset --add_classification --iterative_gradients --batch_size 10 --pretrain_weight_name ./snapshot/resnet50_10_pre_train_21 --encoder resnet50 --seed 42 --epochs 100 --save_folder lrp0_resnet50_lab1464_lr1e-5_s42

Note: The way for counting epochs differs between the semisupervised and supervised datasets. Therefore, you need to set a higher value for the epochs argument when training the UNet.
