Enhanced Classification of Diabetic Retinopathy via Vessel Segmentation: A Deep Ensemble Learning Approach
Bibliographic record
Abstract
Diabetic Retinopathy (DR), a medical condition that impairs the blood vessels within the eye, is increasingly prevalent.Unchecked progression of DR can lead to significant visual impairment or total blindness.Traditional techniques for automatic DR detection, primarily reliant on computer vision systems, often fail to adequately encapsulate the inherent complexity of the disease, resulting in suboptimal categorization of DR stages, particularly the early ones.However, deep ensemble learning has emerged as a potent tool for the accurate detection and classification of DR using retinal images.In this study, deep ensemble models are proposed that initially segment the retinal image using the Canny operator and subsequently detect and classify all DR categories using the publicly available DRIVE dataset.Each model, crafted with subtle architectural distinctions or trained on distinct data subsets, was designed to capture varying disease attributes.A threshold was established to accurately categorize DR severity into mild, moderate, or severe cases.The results indicate a significant enhancement in the performance of both segmentation and DR detection through deep ensemble learning, compared to individual models.The ensemble approach effectively amalgamated the collective knowledge of the models, yielding superior accuracy, robustness to data variations, and improved generalization capabilities.This cost-effective computational method achieves an accuracy score of 98.65% in DR detection and classification.By synthesizing the predictions of multiple models, the ensemble captured a wider spectrum of disease patterns, thereby bolstering the system's overall effectiveness in DR diagnosis.The findings underscore the enhanced accuracy and robustness attained through the ensemble approach, surpassing the performance of individual models.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
