Introduction

Data and code for NeurIPS 2021 Paper "IconQA: A New Benchmark for Abstract Diagram Understanding and Visual Language Reasoning".

We propose a new challenging benchmark, icon question answering (IconQA), which aims to highlight the importance of abstract diagram understanding and comprehensive cognitive reasoning in real-world diagram word problems. For this benchmark, we build up a large-scale IconQA dataset that consists of three sub-tasks: multi-image-choice, multi-text-choice, and filling-in-the-blank. Compared to existing VQA benchmarks, IconQA requires not only perception skills like object recognition and text understanding, but also diverse cognitive reasoning skills, such as geometric reasoning, commonsense reasoning, and arithmetic reasoning.

There are three different sub-tasks in IconQA:

• 57,672 multi-image-choice questions
• 31,578 multi-text-choice questions
• 18,189 filling-in-the-blank questions

Sub-Tasks	Train	Validation	Test	Total
Multi-image-choice	34,603	11,535	11,535	57,672
Multi-text-choice	18,946	6,316	6,316	31,578
Filling-in-the-blank	10,913	3,638	3,638	18,189

We further develop a strong model, Patch-TRM, which parses the diagram in a pyramid layout and applies cross-modal Transformers to learn the joint diagram-question feature. Patch-TRM takes patches parsed from a hierarchical pyramid layout and embeds them through ResNet pre-trained on our Icon645 dataset. The joint diagram-question feature is learned via cross-modal Transformers followed by the attention module.

Download the IconQA Dataset

You can download IconQA here or from Google Drive, then unzip the dataset into root_dir/data.

Next, download pre-trained models here or from Google Drive, then unzip them into root_dir.

Or run the command by:

. tools/download_data_and_models.sh

Run the Patch-TRM model for IconQA

Requirements

python=3.6.9
h5py=3.1.0
huggingface-hub=0.0.12
numpy=1.19.5
Pillow=8.3.1
torch=1.9.0+cu111
torchvision=0.10.0+cu111
tqdm=4.61.2

Install all required python dependencies:

pip install -r requirements.txt

Process IconQA Data

Generate the question dictionary:

cd tools
python create_dictionary.py

Generate answer labels:

python create_ans_label.py

Generate image features

Generate the image patch features from the icon classifier model that is pre-trained on our proposed Icon645 dataset:

python generate_img_patch_feature.py --icon_pretrained True --patch_split 79

• --icon_pretrained True: the backbone network is pre-trained on icon data
• --patch_split 79: the image is hierarchically parsed into 79 patches before feature extraction

Generate the image choice features for the multi-image-choice sub-task from the icon classifier model that is pre-trained on our proposed Icon645 dataset:

python generate_img_choice_feature.py --icon_pretrained True

• --icon_pretrained True: the backbone network is pre-trained on icon data

Optionally, you can set --icon_pretrained False to generate image features from the ResNet101 model pre-trained on natural image dataset ImageNet.

The above steps are time-consuming and can take several hours. Instead, you can alternatively download the extracted features here or from Google Drive, then unzip them into root_dir/data. Or run the command by:

. tools/download_img_feats.sh

Icon645 Dataset

In addition to IconQA, we also present Icon645, a large-scale dataset of icons that cover a wide range of objects:

• 645,687 colored icons
• 377 different icon classes (class mapping is stored in icon645_classes.json)

These collected icon classes are frequently mentioned in the IconQA questions. In this work, we use the icon data to pre-train backbone networks on the icon classification task in order to extract semantic representations from abstract diagrams in IconQA. On top of pre-training encoders, the large-scale icon data could also contribute to open research on abstract aesthetics and symbolic visual understanding.

You can download Icon645 here or from Google Drive. Or run the command by:

cd data
wget https://iconqa2021.s3.us-west-1.amazonaws.com/icon645.zip
unzip icon645.zip
