Abstract:Diabetic retinopathy is a common complication of diabetes, that affects blood vessels in the light-sensitive tissue called the retina. It is the most common cause of vision loss among people with diabetes and the leading cause of vision impairment and blindness among working-age adults. Recent progress in the use of automated systems for diabetic retinopathy diagnostics has offered new challenges for the industry, namely the search for a less resource-intensive architecture, e.g., for the development of low-co… Show more
“…The reasons for this would require further study but it may be conceptually important that the performance of the model depends on factors other than image resolution [15] or set size alone, with the network architecture possibly also an important factor contributing to model performance. The E cientNet [6] family of models has shown among other Convolutional Neural Networks e cacy in terms of performance and speed using commercially available GPU processing capabilities in the classi cation of skin lesions [16], CT lung scans [17] and diabetic retinopathy [18] but this is the probably one of the rst papers employing this model in paediatric elbow radiographs. In this study, a lower powered B1 version of the model was employed as compared to higher (i.e.…”
BackgroundTo compare the performance of an AI model based on strategies designed to overcome small sized development sets to pediatric ER physicians at a classification triage task of pediatric elbow radiographs. Methods1,314 pediatric elbow lateral radiographs (mean age: 8.2 years) were retrospectively retrieved, binomially classified based on their annotation as normal or abnormal (with pathology), and randomly partitioned into a development set (993 images), tuning set (109 images), second tuning set (100 images) and test set (112 images). The AI model was trained on the development set and utilized the EfficientNet B1 compound scaling network architecture and online augmentations. Its performance on the test set was compared to a group of five physicians (inter-rater agreement: fair). Statistical analysis: AUC of AI model - DeLong method. Performance of AI model and physician groups - McNemar test. ResultsAccuracy of the model on the test set - 0.804 (95% CI, 0.718 - 0.873), AUROC - 0.872 (95% CI, 0.831 - 0.947). AI model performance compared to the physician group on the test set - sensitivity 0.790 (95% CI 0.684 to 0.895) vs 0.649 (95% CI 0.525 to 0.773), p value 0.088; specificity 0.818 (95% CI 0.716 to 0.920) vs 0.873 (95% CI 0.785 to 0.961), p value 0.439.ConclusionsThe AI model for elbow radiograph triage designed with strategies to optimize performance for a small sized development set showed comparable performance to physicians.

“…There are two main schools of thought in DR categorization research: traditional, expert-led methods, and cutting-edge, machine-learning-based methods, more in-depth analysis of these techniques is provided below. For instance, Alexandr et al [19] Compares a new improved structure (EfficientNet) to two extensively used traditional architectures (DenseNet, ResNet) . The APTOS Symposium dataset is used to classify the retinal picture into one of five classes.…”
Vision loss can be avoided if diabetic retinopathy (DR) is diagnosed and treated promptly. Following are the main 5 DR stages: none, moderate, mild, proliferate, and severe. In this study, a deep learning (DL) model is presented that diagnoses all 5 stages of DR with more accuracy than previous methods. The suggested method presents two scenarios: case 1 with image enhancement using contrast limited adaptive histogram equalization (CLAHE) filtering algorithm in conjunction with an Enhanced Super-resolution generative adversarial network (ESRGAN), and case 2 without image enhancement; augmentation techniques are then performed to generate a balanced dataset utilizing the same parameters for both cases. Using Inception-V3 applied to the Asia Pacific Tele-Ophthalmology Society (APTOS) datasets, the developed model achieved an accuracy of 98.7% for case 1 and 80.87% for case 2, which is greater than existing methods for detecting the five stages of DR. It was demonstrated that using CLAHE and ESRGAN improves a model's performance and learning ability.
“…After the said Conv layer, the squeeze-and-excitation connects to a DO layer for added regularization ⊕ with the previous Conv → BN layers. The combinations of these approaches made EfficientNet one of the most cost-efficient DCNN and highly accurate models in recent years [20] . Fig.…”
