Abstract Prostate cancer is the one of most dominant among males. It represents leading death causes worldwide. Due to current evolution artificial intelligence in medical imaging, deep learning has been successfully applied diseases diagnosis. However, recent studies prostate classification suffers from either low accuracy or lack data. Therefore, present work introduces a hybrid framework for early and accurate segmentation using learning. The proposed consists two stages, namely stage stage. In stage, 8 pretrained convolutional neural networks were fine-tuned Aquila optimizer used classify patients normal ones. If patient diagnosed with cancer, segmenting cancerous spot overall image U-Net can help diagnosis, here comes importance trained on 3 different datasets order generalize framework. best reported accuracies are 88.91% MobileNet “ISUP Grade-wise Cancer” dataset 100% ResNet152 “Transverse Plane Dataset” precisions 89.22% 100%, respectively. model gives an average AUC 98.46% 0.9778, respectively, “PANDA: Resized Train Data (512 × 512)” dataset. results give indicator acceptable performance

Abstract Autism Spectrum Disorder (ASD) is a developmental condition resulting from abnormalities in brain structure and function, which can manifest as communication social interaction difficulties. Conventional methods for diagnosing ASD may not be effective the early stages of disorder. Hence, diagnosis crucial to improving patient's overall health well-being. One alternative method autism facial expression recognition since autistic children typically exhibit distinct expressions that aid distinguishing them other children. This paper provides deep convolutional neural network (DCNN)-based real-time emotion system kids. The proposed designed identify six emotions, including surprise, delight, sadness, fear, joy, natural, assist medical professionals families recognizing intervention. In this study, an attention-based YOLOv8 (AutYOLO-ATT) algorithm proposed, enhances model's performance by integrating attention mechanism. outperforms all classifiers metrics, achieving precision 93.97%, recall 97.5%, F1-score 92.99%, accuracy 97.2%. These results highlight potential real-world applications, particularly fields where high essential.

Abstract This paper proposes a hybrid Modified Coronavirus Herd Immunity Aquila Optimization Algorithm (MCHIAO) that compiles the Enhanced Optimizer (ECHIO) algorithm and (AO). As one of competitive human-based optimization algorithms, (CHIO) exceeds some other biological-inspired algorithms. Compared to CHIO showed good results. However, gets confined local optima, accuracy large-scale global problems is decreased. On hand, although AO has significant exploitation capabilities, its exploration capabilities are insufficient. Subsequently, novel metaheuristic optimizer, (MCHIAO), presented overcome these restrictions adapt it solve feature selection challenges.

In recent years, Sign Language Recognition (SLR) has become an additional topic of discussion in the human–computer interface (HCI) field. The most significant difficulty confronting SLR recognition is finding algorithms that will scale effectively with a growing vocabulary size and limited supply training data for signer-independent applications. Due to its sensitivity shape information, automated based on hidden Markov models (HMMs) cannot characterize confusing distributions observations gesture features sufficiently precise parameters. order simulate uncertainty hypothesis spaces, many scholars provide extension HMMs, utilizing higher-order fuzzy sets generate interval-type-2 HMMs. This expansion helpful because it brings fuzziness conventional HMM mapping under control. neutrosophic are used this work deal indeterminacy practical setting. Existing HMMs consider uncertain information includes indeterminacy. However, model successfully identifies best route between states when there vagueness. three membership functions (truth, indeterminate, falsity grades) more layers autonomy assessing HMM’s uncertainty. approach could be extensive hence seeks solve scalability issue. addition, may function independently signer, without needing gloves or any other input devices. experimental results demonstrate nearly as computationally difficult but similar performance robust variations.
