Abstract Deep learning models have been widely used in electroencephalogram (EEG) analysis and obtained excellent performance. But the adversarial attack defense for them should be thoroughly studied before putting into safety-sensitive use. This work exposes an important safety issue deep-learning-based brain disease diagnostic systems by examining vulnerability of deep diagnosing epilepsy with electrical activity mappings (BEAMs) to white-box attacks. It proposes two methods, Gradient Perturbations BEAMs (GPBEAM), Differential Evolution (GPBEAM-DE), which generate EEG samples, first time perturbing densely sparsely respectively, find that these BEAMs-based samples can easily mislead models. The experiments use data from CHB-MIT dataset types victim each has four different neural network (DNN) architectures. is shown that: (1) BEAM-based produced proposed methods this paper are aggressive BEAM-related as input internal DNN architectures, but unaggressive EEG-related raw top success rate attacking up 0.8 while only 0.01; (2) GPBEAM-DE outperforms GPBEAM when they same model under a distortion constraint, former 0.59 latter; (3) simple modification GPBEAM/GPBEAM-DE will make it aggressiveness both BEAMs-related (with 0.64), capacity enhancement done without any cost increment. goal study not medical systems, raise concerns about hope lead safer design.

Abstract Background The purpose of this study is to investigate the use radiomics and deep features obtained from multiparametric magnetic resonance imaging (mpMRI) for grading prostate cancer. We propose a novel approach called multi-flavored feature extraction or tensor, which combines four mpMRI images using eight different fusion techniques create 52 datasets each patient. evaluate effectiveness in cancer compare it traditional methods. Methods used PROSTATEx-2 dataset consisting 111 patients’ T2W-transverse, T2W-sagittal, DWI, ADC images. merge T2W, images, namely Laplacian Pyramid, Ratio low-pass pyramid, Discrete Wavelet Transform, Dual-Tree Complex Curvelet Fusion, Weighted Principal Component Analysis. Prostate were manually segmented, extracted Pyradiomics library Python. also an Autoencoder extraction. five sets train classifiers: all features, linked with PCA, combination features. processed data, including balancing, standardization, correlation, Least Absolute Shrinkage Selection Operator (LASSO) regression. Finally, we nine classifiers classify Gleason grades. Results Our results show that SVM classifier PCA achieved most promising results, AUC 0.94 balanced accuracy 0.79. Logistic regression performed best when only 0.93 0.76. Gaussian Naive Bayes had lower performance compared other classifiers, while KNN high PCA. Random Forest well achieving Voting showed higher 2 highest performance, 0.95 0.78.

Segmentation models for clinical data experience severe performance degradation when trained on a single client from one domain and distributed to other clients different domain. Federated Learning (FL) provides solution by enabling multi-party collaborative learning without compromising the confidentiality of clients' private data. In this paper, we propose cross-domain FL method Weakly Supervised Semantic (FL-W3S) white blood cells in microscopic images. We perform model training multiple with distributions obtain global aggregated using only image-level class labels semantic segmentation cells. A multi-class token transformer learns relationship between patch tokens during generates class-specific localization maps mask predictions. To rectify maps, use patch-level pairwise affinity obtained patch-to-patch attention. evaluate proposed two datasets domains. Our experimental results show that datasets, there is 2.56% 1.39% increase over existing state-of-the-art methods. The combination federated while preserving privacy, alongside cell techniques precise identification, enhances diagnostic accuracy personalized treatment strategies applications, particularly hematology pathology. More specifically, it involves isolating smear further analysis such as automated counting, morphological analysis, classification, disease diagnosis monitoring.
