Brain tumors must be classified to determine their severity and appropriate therapy. Applying Artificial Intelligence medical imaging has enabled remarkable developments. The presented framework classifies patients with brain high accuracy efficiency using CNN, pre-trained models, the Manta Ray Foraging Optimization (MRFO) algorithm on X-ray MRI images. Additionally, CNN Transfer Learning (TL) hyperparameters will optimized through MRFO, resulting in improved performance of model. Two public datasets from Kaggle were used build models. first dataset consists two classes, while 2nd includes three contrast-enhanced T1-weighted classes. First, a patient should diagnosed as "Healthy" (or "Tumor"). When scan returns result "Healthy," no abnormalities brain. If reveals that tumor, an performed them. After that, type tumor (i.e., meningioma, pituitary, glioma) identified second proposed classifier. A comparative analysis models two-class showed VGG16's model outperformed other Besides, Xception achieved best results three-class dataset. manual review misclassifications was conducted reasons for correct evaluation suggested architecture yielded 99.96% X-rays 98.64% MRIs. deep learning most current

Early detection of brain tumors in MRI images is vital for improving treatment results. However, deep learning models face challenges like limited dataset diversity, class imbalance, and insufficient interpretability. Most studies rely on small, single-source datasets do not combine different feature extraction techniques better classification. To address these challenges, we propose a robust explainable stacking ensemble model multiclass tumor that combines EfficientNetB0, MobileNetV2, GoogleNet, Multi-level CapsuleNet, using CatBoost as the meta-learner improved aggregation classification accuracy. This approach captures complex characteristics while enhancing robustness The proposed integrates CapsuleNet within framework, utilizing to improve We created two large by merging data from four sources: BraTS, Msoud, Br35H, SARTAJ. tackle applied Borderline-SMOTE augmentation. also utilized methods, along with PCA Gray Wolf Optimization (GWO). Our was validated through confidence interval analysis statistical tests, demonstrating superior performance.

Abstract Brain tumors are very dangerous as they cause death. A lot of people die every year because brain tumors. Therefore, accurate classification and detection in the early stages can help recovery. Various deep learning techniques have achieved good results tumor classification. The traditional methods training neural network from scratch time-consuming last for weeks training. this work, we proposed an ensemble approach depending on transfer that utilizes pre-trained models DenseNet121 InceptionV3 to detect three forms tumors: meningioma, glioma, pituitary. While developing model, some changes were made architecture by replacing their classifiers (fully connected SoftMax layers) with a new classifier adopt recent task. In addition, gradient-weighted class activation maps (Grad-CAM) explainable model verify achieve high confidence. suggested was validated using publicly available dataset 99.02% accuracy, 98.75% precision, 98.98% recall, 98.86% F1 score. outperformed others detecting classifying MRI data, verifying degree trust.

The use of MRI analysis for BTD and tumor type detection has considerable importance within the domain machine vision. Numerous methodologies have been proposed to address this issue, significant progress achieved in via deep learning (DL) approaches. While majority offered approaches using artificial neural networks (ANNs) (DNNs) demonstrate satisfactory performance Bayesian Tree Descent (BTD), none these research studies can ensure optimality employed model structure. Put simply, there is room improvement efficiency models BTD. This introduces a novel approach optimizing configuration Convolutional Neural Networks (CNNs) Artificial issue. suggested employs (CNN) purpose segmenting brain MRIs. model's configurable hyper-parameters are tuned genetic algorithm (GA). Multi-Linear Principal Component Analysis (MPCA) used decrease dimensionality segmented features pictures after they segmented. Ultimately, segmentation procedure executed an Network (ANN). In network (ANN), (GA) sets ideal number neurons hidden layer appropriate weight vector. effectiveness was assessed by utilizing BRATS2014 BTD20 databases. results indicate that method classify samples from two databases with average accuracy 98.6 % 99.1 %, respectively, which represents at least 1.1 over preceding methods.

Abstract Security is a crucial concern in the Internet of Things (IoT) ecosystem. Due to IoT devices' constrained processing and storage resources, providing reliable security solutions challenging. Encryption one most commonly used techniques secure user data against unauthorized access. Therefore, it essential develop encryption that have minimal impact on performance devices. This study introduces hybrid approach combines symmetric blowfish with asymmetric elliptic curves. Blowfish encrypt large volumes data, which could otherwise affect execution time. In contrast, curve cryptography utilized ensure private key, has small size does not increase time significantly. The suggested provides advantages both methods, leading an improvement throughput reduction proposed was evaluated, yielding promising results comparison other cryptographic algorithms. show optimization more than 15% efficiency by solution. represents least resources.
