Challenges Facing KOA Grading Using Deep Learning
Suggestions to Help in Solving KOA Grading
In my opinion, the latest deep learning models and transformers can help solve this problem. For instance, ensemble deep-learning networks have been developed to predict a consistent and accurate KL grade for knee OA severity using a deep-learning approach. Transfer learning-assisted 3D deep learning models have also been used for knee OA detection[13]. Moreover, pre-trained SOTA deep learning models including ConvNeXt and ConvNeXt V2 have been fine-tuned using the ordinal loss function for automatic detection of knee OA stages according to the KL grading system[11]. These models have shown promising results and can be further improved by using large-scale datasets with accurate annotations and by developing models that can handle visual disturbances.
Another potential concept for solving KOA Grading problem can be the Mixture of experts (MoE). This can be a promising approach for knee osteoarthritis (KOA) grading system using deep learning. MoE is a neural network architecture that combines multiple sub-networks, each of which specializes in a different part of the input space. MoE has been used for various medical image analysis tasks, including segmentation, classification, and detection. MoE can be used to handle the ordinal nature of the KL grading system by partitioning the prediction space into multiple regions, each of which corresponds to a different KL grade.
