Classification of Fracture and Normal Shoulder Bone X-Ray Images Using Ensemble and Transfer Learning With Deep Learning Models Based on Convolutional Neural Networks
share
Shoulder bone Xray images were classified and compared via deep learning models based on convolutional neural network (CNN) using transfer learning and ensemble learning in this study to help physicians diagnose and apply required treatment for shoulder fractures. CNN based built deep learning models herein are; ResNet, ResNeXt, DenseNet, VGG, Inception and MobileNet. Moreover, a classification was also performed by Spinal fully connected (Spinal FC) adaptations of all models. Transfer learning was applied for all these classification procedures. Two different ensemble learning (EL) models were established based on performance of classification results obtained herein. The highest Cohens Kappa score of 0.6942 and highest classification test accuracy of 84.72% were achieved in EL2 model, and the highest AUC score of 0.8862 in EL1.
