UNK-VQA: A Dataset and A Probe into Multi-modal Large Models' Abstention Ability

A VQA dataset that includes unanswerable questions.

Code contribution: Fangkai Jiao (90%) and Yangyang Guo (10%).

The dataset is released at google drive.

Dataset Structure

The dataset is structured as follows:

- images-train
    - COCO-*.jpg
    - ...
- images-val
    - COCO-*.jpg
    - ...
- annt_train.json
- annt_val.json
- annt_test.json

Perturbation Types

There are 5 perturbation types in our dataset, and a short illustration is as follows:

Annotation Json File Illustration

In specific, each json file shares a similar structure (We show one example of the annotation below):

{
    "answer_map": {
        "1": "I don't know (e.g., beyond my knowledge)",
        "2": "Not sure (e.g., multiple answers)",
        "3": "I cannot answer (e.g., difficult question)"
    },
    "reason_map": {
        "1": "It has multiple plausible answers",
        "2": "It is difficult to understand",
        "3": "The image lacks important concepts/information",
        "4": "It requires higher-level knowledge to answer"
    },
    "alter_type_map": {
        "T-1": "word replacement",
        "T-2": "semantic negation",
        "I-1": "image replacement",
        "I-2": "image mask",
        "I-3": "image copy and move"
    }
