Introduction Brain tumor (BT) classification is crucial yet challenging due to the complex and varied nature of these tumors. We present a novel approach combining Pyramid Vision Transformer (PVT) with an adaptive deformable attention mechanism Topological Data Analysis (TDA) address complexities BT detection. While PVT have been explored in prior work, we introduce key innovations enhance their performance for medical image analysis. Methods developed that dynamically adjusts receptive fields based on complexity, focusing critical regions MRI scans. The also incorporates sampling rate hierarchical dynamic position embeddings context-aware multi-scale feature extraction. Feature channels are partitioned into specialized groups via offset group improve diversity, strategy further integrates local global contexts yield refined representations. Additionally, applying TDA images extracts meaningful topological patterns, followed by Random Forest classifier final classification. Results method was evaluated Figshare brain dataset. It achieved 99.2% accuracy, 99.35% recall, 98.9% precision, 99.12% F1-score, Matthews correlation coefficient (MCC) 0.98, LogLoss 0.05, average processing time approximately 6 seconds per image. Discussion These results underscore method's ability combine detailed extraction insights, significantly improving accuracy efficiency proposed offers promising tool more reliable rapid diagnosis.

Опубликована: Май 29, 2025

Accurate segmentation of brain tumors in magnetic resonance imaging (MRI) remains a challenging task due to heterogeneous tumor structures, varying intensities across modalities, and limited annotated data. Deep learning has significantly advanced accuracy; however, it often suffers from sensitivity hyperparameter settings generalization. To overcome these challenges, bio-inspired metaheuristic algorithms have been increasingly employed optimize various stages the deep pipeline—including tuning, preprocessing, architectural design, attention modulation. This review systematically examines developments 2015 2025, focusing on integration nature-inspired optimization methods such as Particle Swarm Optimization (PSO), Genetic Algorithm (GA), Differential Evolution (DE), Grey Wolf Optimizer (GWO), Whale (WOA), novel hybrids including CJHBA BioSwarmNet into learning-based frameworks. A structured multi-query search strategy was executed using Publish or Perish Google Scholar Scopus databases. Following PRISMA guidelines, 3895 records were screened through automated filtering manual eligibility checks, yielding curated set 106 primary studies. Through bibliometric mapping, methodological synthesis, performance analysis, we highlight trends algorithm usage, application domains (e.g., architecture search), outcomes measured by metrics Dice Similarity Coefficient (DSC), Jaccard Index (JI), Hausdorff Distance (HD), ASSD. Our findings demonstrate that enhances accuracy robustness, particularly multimodal involving FLAIR T1CE modalities. The concludes identifying emerging research directions hybrid optimization, real-time clinical applicability, explainable AI, providing roadmap for future exploration this interdisciplinary domain.
