The primary objective of this project is to develop an automated system for Diabetic Retinopathy (DR) detection that is both accurate and scalable. The key objectives include: 1. Data Preprocessing: To clean and preprocess the Diabetic Retinopathy Detection dataset, ensuring the quality of the input images and addressing issues such as noise and image variability. 2. Model Development: To implement and train deep learning models such as MobileNet, ResNet50, and hybrid models combining MobileNet + GNN and MobileNet + RNN. These models will classify DR into five stages, improving accuracy by learning both spatial and temporal patterns in retinal images. 3. Active Learning (AL): To integrate Active Learning (AL) into the model training process, enabling the system to actively select and learn from the most informative samples, reducing the reliance on large labeled datasets and improving model efficiency. 4. Model Evaluation: To evaluate the performance of the models based on key metrics such as accuracy, precision, recall, and F1-score. Additionally, the models will be assessed for their ability to generalize to new, unseen data. 5. Scalability: To ensure that the developed system can be scaled to work with larger datasets and deployed in low-resource environments, providing an efficient and accessible solution for DR detection.
Diabetic Retinopathy (DR) is a severe eye disease in diabetics that can lead to retinal damage and blindness if not properly managed. Traditional DR screening by ophthalmologists is time-consuming, prompting the need for more efficient methods. This project leverages Deep Learning (DL) to automate DR detection using MobileNet, a lightweight model trained on 3,662 high-resolution fundus images from the APTOS dataset hosted on Kaggle. The MobileNet model classifies DR into five stagesβzero through four. To enhance performance further, we explore hybrid models combining MobileNet with other architectures: MobileNet + Graph Neural Network (GNN) and MobileNet + Recurrent Neural Network (RNN). The MobileNet + GNN hybrid aims to capture complex spatial relationships within retinal images, potentially improving classification by interpreting structural patterns. The MobileNet + RNN hybrid seeks to address sequential dependencies and temporal patterns, enhancing the model's ability to detect nuanced changes across different DR stages. These hybrid approaches aim to optimize DR detection, improving both accuracy and efficiency.
