About Dataset
1) Data Introduction
• The Marvel Heroes Dataset is was created by collecting images of various characters from the Marvel Cinematic Universe (MCU). It consists of eight main characters: Black Widow, Captain America, Doctor Strange, Hulk, Iron Man, Loki, Spider-Man, and Thanos.2) Data Utilization
(1) Characteristics of the Marvel Heroes Dataset: • The dataset is evenly structured across major MCU characters, providing a balanced set of images for each class. • It is suitable for character recognition, feature learning, and the development of classification models based on facial features and costumes. (2) Applications of the Marvel Heroes Dataset: • Development of Character Classification and Recognition Models: The dataset can be used to train and evaluate AI models that classify various characters such as Black Widow, Spider-Man, and Thanos. • Fan Content Creation and Creative Applications: It can also be utilized in creative projects, such as generating fan art or developing theme-based classification applications.Meta Data

Model Performance
Downstream classification accuracy is an indicator used to evaluate the usefulness of synthetic data. It measures whether synthetic data performs similarly to real data. The method involves training the same model separately on real data and synthetic data, and then comparing the accuracies of the two models. Interpretation: A high accuracy rate means that the model trained on synthetic data performs similarly to the one trained on real data, indicating that the synthetic data is of high quality and well represents the real data.
The closer to zero or the lower the value, the better (▼)
Quality
KID (Kernel Inception Distance) is a metric used to evaluate the similarity between generated images and real images. It compares the differences between the two sample distributions using Kernel Mean Embedding, without assuming a normal distribution. Interpretation: A lower KID score suggests that generated images are more similar to real images, with a score close to 0 being ideal. Specifically, a score below 0.01 indicates very high similarity.

Perceptual Similarity
Learned Perceptual Image Patch Similarity (LPIPS) is a metric used to measure the visual similarity between two images by utilizing neural networks to extract key features and calculate the distance between them. High LPIPS value: Indicates high similarity between images, raising the risk of information leakage. Low LPIPS value: Suggests that synthetic images are perceptually different from real images, indicating a lower risk of sensitive information leakage.
The closer to zero or the lower the value, the better (▼)
Structural Similarity
The Structural Similarity Index Measure (SSIM) is a metric used to assess the similarity between two images. It is primarily used to compare the quality of a restored or compressed image with the original image. SSIM measures visual similarity by considering brightness, contrast, and structure.
High SSIM value (0.9 or above): Indicates that the synthetic image is very similar to the real image, which may increase the risk of information leakage.
Low SSIM value (0.6 or below): Indicates low similarity and reduced risk of leakage.
