Adaptive machine learning has increasing importance due to its ability classify a data stream and handle the changes in distribution. Various resources, such as wearable sensors medical devices, can generate with an imbalanced distribution of classes. Many popular oversampling techniques have been designed for batch rather than continuous stream. This work proposes self-adjusting window improve adaptive classification based on minimizing cluster distortion. It includes two models; first chooses only previous instances that preserve coherence current chunk’s samples. The second model relaxes strict filter by excluding examples last chunk. Both models include generating synthetic points actual points. evaluation proposed using Siena EEG dataset showed their performance several classifiers. best results obtained Random Forest which Sensitivity reached 96.83% Precision 99.96%.

Epilepsy is one of the most common brain disorders, and seizures epilepsy have severe adverse effects on patients. Real-time seizure detection using electroencephalography (EEG) signals an important research area aimed at improving diagnosis treatment epilepsy. This paper proposed a real-time approach based EEG signal for detecting STFT Google-net convolutional neural network (CNN). The CHB-MIT database was used to evaluate performance, received results 97.74 % in accuracy, 98.90 sensitivity, 1.94 false positive rate. Additionally, method implemented manner sliding window technique. processing time just 0.02 s every 2-s episode achieved average 9.85- second delay each onset.

Abstract Brain disorders pose a substantial global health challenge, persisting as leading cause of mortality worldwide. Electroencephalogram (EEG) analysis is crucial for diagnosing brain disorders, but it can be challenging medical practitioners to interpret complex EEG signals and make accurate diagnoses. To address this, our study focuses on visualizing in format easily understandable by professionals deep learning algorithms. We propose novel time–frequency (TF) transform called the Forward–Backward Fourier (FBFT) utilize convolutional neural networks (CNNs) extract meaningful features from TF images classify disorders. introduce concept eye-naked classification, which integrates domain-specific knowledge clinical expertise into classification process. Our demonstrates effectiveness FBFT method, achieving impressive accuracies across multiple using CNN-based classification. Specifically, we achieve 99.82% epilepsy, 95.91% Alzheimer’s disease (AD), 85.1% murmur, 100% mental stress Furthermore, context naked-eye 78.6%, 71.9%, 82.7%, 91.0% AD, stress, respectively. Additionally, incorporate mean correlation coefficient (mCC) based channel selection method enhance accuracy further. By combining these innovative approaches, enhances visualization signals, providing with deeper understanding images. This research has potential bridge gap between image visual interpretation, better detection improved patient care field neuroscience.

Seizure is a common neurological disorder that usually manifests itself in recurring seizure, and these seizures can have serious impact on person's life health. Therefore, early detection diagnosis of seizure crucial. In order to improve the efficiency this paper proposes new method, which based discrete wavelet transform (DWT) multi-channel long- short-term memory-like spiking neural P (LSTM-SNP) model. First, signal decomposed into 5 levels by using DWT obtain features components at different frequencies, series time-frequency coefficients are extracted. Then, used train LSTM-SNP model perform detection. The proposed method achieves high accuracy CHB-MIT dataset: 98.25% accuracy, 98.22% specificity 97.59% sensitivity. This indicates epilepsy show competitive performance.

Epilepsy is a chronic neurological disease associated with abnormal neuronal activity in the brain. Seizure detection algorithms are essential reducing workload of medical staff reviewing electroencephalogram (EEG) records. In this work, we propose novel automatic epileptic EEG method based on Stockwell transform and Transformer. First, S-transform applied to original segments, acquiring accurate time-frequency representations. Subsequently, obtained matrices grouped into different rhythm blocks compressed as vectors these sub-bands. After that, feature fed Transformer network for selection classification. Moreover, series post-processing methods were introduced enhance efficiency system. When evaluating public CHB-MIT database, proposed algorithm achieved an accuracy 96.15%, sensitivity 96.11%, specificity 96.38%, precision 96.33%, area under curve (AUC) 0.98 segment-based experiments, along 96.57%, false rate 0.38/h, delay 20.62 s event-based experiments. These outstanding results demonstrate feasibility implementing seizure future clinical applications.
