Robust and Interpretable Chest X-ray Classification via Diffusion Purification and Concept-Based Adversarial Detection.
Adversarial attack is an approach that primarily compromise the integrity of deep learning system in medical imaging by adding subtle changes to the model inputs that humans don't notice, it leads the model to make an incorrect decision, so the attacker can corrupt both the input data and the predic...

In this paper A hybrid detection method based on diffusion purification, deep feature extraction, and ensemble learning has been proposed to address this issue using chest x-ray images. Two phases make it up. First, cleansing the adversarial samples. This is accomplished by a diffusion model. The samples are regenerated to remove the small perturbations fully. In the second phase, the images are categorized into two groups. Clean and purified images are collected in a safe category, while harmful images are unsafe category. In the second stage, we utilize a pre-trained ResNet18 feature extractor to retrieve salient from chest X-rays. Furthermore, a Random Forest model classifies the features obtained from the ResNet18 model into harmful and non-harmful image. The experimental results show that the proposed framework can detect more than 99% of adversarial samples. The satisfactory detection rate of the proposed purification and ensemble-based feature detection for making AI-assisted disease detection more reliable and safer. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2025 holdings: @attributes: islocal: N |
