# ABNN-WSI-Classification
This repository contains the code of the method presented in the paper [Gigapixel Histopathological Image Analysis Using
Attention-Based Neural Networks](https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9447746).
The structure of the proposed CNN consists in a compressing path and a learning path. In the compressing path, the gigapixel image is packed into a grid-based feature map by using a residual network devoted to the feature extraction of each patch into which the image has been divided. In the learning path, attention modules (Maxpooling and Minpooling) are applied to the grid-based feature map, taking into account spatial correlations of neighboring patch features to find regions of interest, which are then used for the final whole slide classification.

# Experiments
The experiments presented in the paper [Gigapixel Histopathological Image Analysis Using
Attention-Based Neural Networks](https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9447746) are based on Camelyon16 and TUPAC 16 datasets. For Camelyon16 a binary classification into Benign and Malignant classes was performed. Regarding TUPAC16 dataset, a regression related to the prediction of the proliferation score based on molecular data was calculated.

New esperiments have been made by using WSI of [BRACS dataset](https://www.bracs.icar.cnr.it/). 
For BRACS dataset, a three-class classification has been performed, by using Atypical, Benign, and Malignant classes for WSIs.

```
To correctly run ```ABNN-WSI.py``` two steps are required: a compressing path and a learning path.

# Step 1: Compressing path
Compressing path to create tensors for the Step 2 can be set by using the parameters ```--mode``` of the script equal to ```TENSORS```.

An example of usage for compressing path is:

```python ABNN_WSI.py --mode TENSOR --model_type RESNET34 --data_dir path-for-loading-images  --gpu_list 0 --seed 0 --save_dir path-to-save-the-tensors --ext svs```

# Step 2: Learning path
Learning path to train and test the model can be set by using the parameters ```--mode``` of the script equal to ```TRAIN```.

An example of usage for learning path is:

```python ABNN_WSI.py --mode TRAIN --data_dir path-for-loading-training-tensors --val_dir path-for-loading-validation-tensors --test_dir path-for-loading-test-tensors --aug_dir path-for-loading-some-augmentation-tensors --aug_dir2 path-for-loading-other-augmentation-tensors --gpu_list 0 --seed 0 --model_path path-to-save-model-for-each-epoch --model_path_fin path-to-save-the-final-model --batch_size 8 --learning_rate 0.00001 --ext pth```
