Orthopedic diseases are widespread worldwide, impacting the body's musculoskeletal system, particularly those involving bones or hips. They have potential to cause discomfort and impair functionality. This paper aims address lack of supplementary diagnostics in orthopedics improve method diagnosing orthopedic diseases. The study uses binary breadth-first search (BBFS), particle swarm optimization (BPSO), grey wolf optimizer (BGWO), whale algorithm (BWAO) for feature selections, BBFS makes an average error 47.29% less than others. Then we apply six machine learning models, i.e., RF, SGD, NBC, DC, QDA, ET. dataset used contains 310 instances distinct features. Through experimentation, RF model led optimal outcomes during comparison remaining with accuracy 91.4%. parameters were optimized using four algorithms: BFS, PSO, WAO, GWO. To check how well works on dataset, this prediction evaluation metrics such as accuracy, sensitivity, specificity, F-score, AUC curve. results showed that BFS-RF can performance original classifier compared others 99.41% accuracy.

Skin cancer classification based on an optimized convolutional neural network and multicriteria decision-making

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: July 27, 2024

Abstract Skin cancer is a type of disease in which abnormal alterations skin characteristics can be detected. It treated if it detected early. Many artificial intelligence-based models have been developed for detection and classification. Considering the development numerous according to various scenarios selecting optimum model was rarely considered previous works. This study aimed develop classification select model. Convolutional neural networks (CNNs) form AlexNet, Inception V3, MobileNet V2, ResNet 50 were used feature extraction. Feature reduction carried out using two algorithms grey wolf optimizer (GWO) addition original features. images classified into four classes based on six machine learning (ML) classifiers. As result, 51 with different combinations CNN algorithms, without GWO ML To best results, multicriteria decision-making approach utilized rank alternatives by perimeter similarity (RAPS). Model training testing conducted International Imaging Collaboration (ISIC) 2017 dataset. Based nine evaluation metrics RAPS method, AlexNet algorithm classical yielded model, achieving accuracy 94.5%. work presents first benchmarking many models. not only reduces time spent but also improves accuracy. The method has proven its robustness problem
