Applying artificial intelligence to disease staging: Deep learning for improved staging of diabetic retinopathy.

PloS one Jun 22, 2017
PURPOSE: Disease staging involves the assessment of disease severity or progression and is used for treatment selection. In diabetic retinopathy, disease staging using a wide area is more desirable than that using a limited area. We investigated if d...
