CLEVR-Per Dataset README
Overview
CLEVR-Per is a cross-modal dataset integrating images, baseline (true) captions, and permuted (false) captions to facilitate research on "compositional understanding" tasks in vision-language models. The dataset is designed to explore VLMs' ability to understand semantic changes in vision and textual entities by swapping attributes vocabulary, creating different semantic expressions. CLEVR-Per contains three subsets: ColPer (color semantics permutation), CntPer (quantity semantics permutation), and MatPer (material semantics permutation), each focusing on specific types of semantic transformations.
Supported Tasks
CLEVR-Per is suitable for the following tasks:
- Compositional Understanding Evaluation: Assessing the model's ability to understand semantic changes. The model selects the most relevant description from baseline caption and permuted caption for a given image, testing its compositional understanding.
- Adversarial Sample Generation: Researchers can generate diverse adversarial samples using baseline and permuted caption for contrastive training, improving the model's ability to detect erroneous semantics.
Data Source and Statistics
The CLEVR-Per dataset is derived from CLEVR [1], with all baseline and permuted captions generated based on predefined rules and templates.
Dataset Statistics and Example
| Subset | Number of Images | Baseline Captions | Permuted Captions |
|---|---|---|---|
| ColPer | 4000 | 16905 | 16905 |
| CntPer | 4000 | 7292 | 7292 |
| MatPer | 4000 | 10589 | 10589 |
Data Structure
| Field Name | Data Type | Description |
|---|---|---|
| image_id | string | Identifier for the image sample |
| image_path | string | Path or URL of the image sample |
| obj1_name | string | Name of the first entity in caption |
| obj2_name | string | Name of the second entity in caption |
| true_caption | string | Baseline caption describing the image |
| false_caption | string | Caption formed by swapping attributes in the baseline caption |
| attributes | list | List of attributes related to both entities |
| id | int | Unique Identifier for the sample |
Example
| Field Name | Data Type | Description |
|---|---|---|
| image_id | string | 000001 |
| image_path | string | CLEVR_mini_000001.png |
| obj1_name | string | sphere |
| obj2_name | string | cube |
| true_caption | string | "yellow sphere and purple cube." |
| false_caption | string | "purple sphere and yellow cube." |
| attributes | list | ["yellow", "purple"] |
| id | int | 100 |
Build Your Dataset with Simple Code
Using simple code, you can build your richer and more diverse negative sample dataset obased on CLEVR-Per.
For example:
- "is This a test true caption"
- "caption This is a true test"
- "a test This is true caption"
import random
def generate_negative_samples(true_caption, num_samples=3):
"""
Efficiently generates negative samples by shuffling the word order of a given caption.
Args:
true_caption (str): The original caption.
num_samples (int): The number of negative samples to generate (default: 3).
Returns:
list: A list of generated negative samples.
"""
words = true_caption.split()
word_count = len(words)
# Limit the number of unique permutations to the factorial of word count if needed
max_unique_permutations = min(num_samples, len(set(random.sample(words, word_count)) for _ in range(num_samples)))
# Use a set to avoid duplicates
negative_samples = {
' '.join(random.sample(words, word_count))
for _ in range(max_unique_permutations * 10) # Extra sampling to reduce duplicates
}
# Convert to list and limit the final count
return list(negative_samples)[:num_samples]
# Example usage
true_caption = "This is a test true caption"
negative_samples = generate_negative_samples(true_caption)
print(negative_samples)
For example:
import random
from PIL import Image
import os
def generate_shuffled_images(image_path, grid_size=(4, 4), num_images=3, output_dir="shuffled_images"):
"""
Efficiently generates multiple images by shuffling blocks of the original image.
Args:
image_path (str): Path to the input image.
grid_size (tuple): Number of rows and columns to split the image (e.g., (4, 4)).
num_images (int): Number of shuffled images to generate.
output_dir (str): Directory to save the generated images.
Returns:

# Load the image and determine dimensions

img_width, img_height = image.size
rows, cols = grid_size
block_width, block_height = img_width // cols, img_height // rows
