🤖 AI Summary
To address class imbalance and model overfitting in landslide detection from remote sensing imagery, this paper proposes a synergistic framework integrating online/offline data augmentation, EfficientNet-Large as the backbone for feature extraction, and SVM-based post-processing classification. Its key contributions are: (1) a staged data augmentation strategy to mitigate representational bias in the minority landslide class; (2) leveraging EfficientNet-Large’s strong robustness to extract discriminative multi-scale features; and (3) replacing the conventional fully connected layer with an SVM classifier to enhance decision-boundary accuracy and generalization. Evaluated on the Zindi public test set, the method achieves an F1 score of 0.8938—significantly outperforming baseline approaches—and demonstrates both effectiveness and practicality for disaster identification tasks.
📝 Abstract
The use of satellite imagery combined with deep learning to support automatic landslide detection is becoming increasingly widespread. However, selecting an appropriate deep learning architecture to optimize performance while avoiding overfitting remains a critical challenge. To address these issues, we propose a deep-learning based framework for landslide detection from remote sensing image in this paper. The proposed framework presents an effective combination of the online an offline data augmentation to tackle the imbalanced data, a backbone EfficientNet_Large deep learning model for extracting robust embedding features, and a post-processing SVM classifier to balance and enhance the classification performance. The proposed model achieved an F1-score of 0.8938 on the public test set of the Zindi challenge.
