This paper proposes a novel approach, BTC-SAGAN-CHA-MRI, for the classification of brain tumors using SAGAN optimized with Color Harmony Algorithm. Brain cancer, its high fatality rate worldwide, especially in case tumors, necessitates more accurate and efficient methods. While existing deep learning approaches tumor have been suggested, they often lack precision require substantial computational time.The proposed method begins by gathering input MR images from BRATS dataset, followed pre-processing step Mean Curvature Flow-based approach to eliminate noise. The pre-processed then undergo Improved Non-Sub sampled Shearlet Transform (INSST) extracting radiomic features. These features are fed into SAGAN, which is Algorithm categorize different types, including Gliomas, Meningioma, Pituitary tumors. innovative shows promise enhancing efficiency classification, holding potential improved diagnostic outcomes field medical imaging. accuracy acquired identification 99.29%. BTC-SAGAN-CHA-MRI technique achieves 18.29%, 14.09% 7.34% higher 67.92%,54.04%, 59.08% less Computation Time when analyzed models, like diagnosis utilizing convolutional neural network transfer (BTC-KNN-SVM-MRI); M3BTCNet: multi model categorization under metaheuristic optimization (BTC-CNN-DEMFOA-MRI), depending upon hierarchical classifier tumour (BTC-Hie DNN-MRI) respectively.

Path planning for mobile robots poses a challenging optimization problem, requiring the discovery of near-optimal path within diverse constraints. Conventional particle swarm (PSO) algorithms encounter limitations in solving constrained problems, vulnerability to local optima, and premature convergence. To address these challenges, this paper proposes bi-population PSO algorithm with random perturbation strategy (BPPSO), which divides particles into two subpopulations. The first subpopulation enhances global search capabilities by considering quality optimal solution randomly selected when updating velocities. second strengthens using linear cognitive coefficient adjustment strategy. Moreover, counter tracks iteration without improvement best position. Upon reaching predefined threshold, is added positions all both subpopulations, increasing diversity enhancing ability escape optima. performance BPPSO was experimentally validated across three benchmark functions four environment models. results have demonstrated that proposed outperforms existing other established terms running time, highlighting feasibility resolving challenge robot planning.

Brain tumors can cause difficulties in normal brain function and are capable of developing various regions the brain. Malignant tumours develop quickly, pass through neighboring tissues, extend to further or central nervous system. In contrast, healthy typically slowly do not invade surrounding tissues. Individuals frequently struggle with sensory abnormalities, motor deficiencies affecting coordination, cognitive impairments memory focus. this research, Utilizing Phase-aware Composite Deep Neural Network Optimized Coati Algorithm for Tumor Identification Based on Magnetic resonance imaging (PACDNN-COA-BTI-MRI) is proposed. First, input images taken from tumour Dataset. To execute this, image pre-processed using Multivariate Fast Iterative Filtering (MFIF) it reduces occurrence over-fitting collected dataset; then feature extraction Self-Supervised Nonlinear Transform (SSNT) extract essential features like model, shape, intensity. Then, proposed PACDNN-COA-BTI-MRI implemented Matlab performance metrics Recall, Accuracy, F1-Score, Precision Specificity ROC analysed. Performance approach attains 16.7%, 20.6% 30.5% higher accuracy; 19.9%, 22.2% 30.1% recall 21.9% 30.8% precision when analysed existing techniques tumor identification MRI-Based Learning Approach Efficient Classification (MRI-DLA-ECBT), Detection Convolutional Methods Chosen Machine Techniques (MRI-BTD-CDMLT) Image CNN-Based Method (MRI-BTID-CNN) methods, respectively.

In the field of medical imaging, accurate segmentation breast tumors is a critical task for diagnosis and treatment cancer. To address challenges posed by fuzzy boundaries, vague tumor shapes, variation in size, illumination variation, we propose new approach that combines U-Net model with spatial attention mechanism. Our method utilizes cascade feature extraction technique to enhance subtle features tumors, thereby improving accuracy. addition, our incorporates mechanism enable network focus on important regions image while suppressing irrelevant areas. This combination techniques leads significant improvements accuracy, particularly challenging cases where have boundaries or shapes. We evaluate suggested Mini-MIAS dataset demonstrate state-of-the-art performance, surpassing existing methods terms sensitivity, specificity. Specifically, achieves an overall accuracy 91%, sensitivity specificity 93%, demonstrating its effectiveness accurately identifying tumors.

Alzheimer's disease (AD) and Parkinson's (PD) are two of the most common forms neurodegenerative diseases. The literature suggests that effective brain connectivity (EBC) has potential to track differences between AD, PD healthy controls (HC). However, how effectively use EBC estimations for research diagnosis remains an open problem. To deal with complex networks, graph neural network (GNN) been increasingly popular in very recent years effectiveness combining GNN techniques unexplored field dementia diagnosis. In this study, a novel directed structure learning (DSL-GNN) was developed performed on imaging power spectrum density (PSD) features. comparison previous studies GNN, our proposed approach enhanced functionality processing directional information, which builds basis more efficiently performing EBC. Another contribution study is creation new framework applying univariate multivariate features simultaneously classification task. DSL-GNN validated four discrimination tasks exhibited best performance, against existing methods, highest accuracy 94.0% (AD vs. HC), 94.2% (PD 97.4% PD) 93.0% HC). word, provides robust analytical networks containing causal information implies promising conditions.
