Detection and Classification of The Osteoarthritis in Knee Joint Using Transfer Learning with Convolutional Neural Networks (CNNs)

Abstract

Osteoarthritis (OA) is a disease of human joints, especially the knee joint, due to significant weight of the body. This disease leads to rupture and degeneration of parts of the cartilage in the knee joint, which causes severe pain. Diagnosis of this disease can be obtained through X-ray. Deep learning has become a popular solution to medical issues due to its fast progress in recent years. This research aims to design and build a classification system to minimize the burden on doctors and help radiologists to assess the severity of the pain, enable them to make an optimal diagnosis and describe the correct treatment. Deep learning-based approaches, such as Convolution Neural Networks (CNNs), have been used to detect knee OA using transfer learning with fine-tuning. This paper proposed three versions of pre-trained networks (VGG16, VGG19, and ResNet50) for handling the classification task. According to the classification results, The proposed model ResNet50 outperformed the other models a validation accuracy of 91.51% has been obtained.

Attention Mechanism Based on a Pre-trained Model for Improving Arabic Fake News Predictions

“…In other words, this model gives more attention to certain words in the text and ignores other words [21]. The attention model is divided into the step-by-step computations of the attention scores, the attention weights, and the context vector [22]. 1-Attention Scores: As in Equation 14, the attention score (e) is computed from two inputs: the encoded hidden states ( ) and the previous decoder output (…”

Transfer Learning Based Traffic Light Detection and Recognition Using CNN Inception-V3 Model

“…Transfer learning is the reuse of a previously learnt model on a new task [3,[12][13][14]30]. It is popular in deep learning since it can build deep neural networks with little training data.…”

“…It is popular in deep learning since it can build deep neural networks with little training data. In most cases, training a fully convolutional network from start is time-consuming and requires a large training data [12,29,30]. Consequently, this issue may be resolved using the benefits of transfer learning with a pre-trained model.…”
