An Explainable Deep Learning Framework for Banana Leaf Disease Detection and Analysis
摘要
The increasing prevalence of fungal infections in banana cultivation specifically Sigatoka, Cordana, and Pestalotiopsis poses a serious threat to crop yield and global agricultural sustainability. This study aims to develop an accurate, interpretable classification model for early-stage detection of banana leaf diseases using image-based deep learning approaches. The BananaLSD dataset, containing annotated leaf images, was utilized to classify samples into four categories: Healthy, Sigatoka, Cordana, and Pestalotiopsis. Four state-of-the-art Convolutional Neural Network (CNN) architectures—EfficientNet-B0, ResNet-50, MobileNet-V2, and SqueezeNet were trained and evaluated using standard metrics. EfficientNet-B0 achieved the highest performance with an accuracy, precision, and recall of 98.41%, significantly outperforming the other models. To address the black-box nature of CNNs and enhance model interpretability, LIME (Local Interpretable Model-agnostic Explanations) and SHAP (SHapley Additive exPlanations) were employed to visualize salient features influencing predictions. The findings confirm the viability of EfficientNet-B0 for high-accuracy classification of banana leaf diseases and demonstrate the utility of XAI frameworks in making AI-driven agricultural diagnostics more transparent and trustworthy.
