Interpretable hybrid model combining CNN-ViT with Grad-CAM and SHAP for transparent mapping of land use changes

Accurate mapping of land use and land cover (LULC) in arid and rapidly urbanizing environments remains challenging due to high spectral similarity among land-cover classes and the inherent topographic and environmental complexity of these regions. This study introduces a novel deep learning (DL)–based framework for m...

LLMs for Zero-Shot Threat Detection via Structured Risk Indicators

It is shown that the quality of the generated risk indicators is the main driver of zero-shot cyber threat detection performance, and that retrieval mainly benefits weaker LLMs by generating more discriminative risk indicators, whereas stronger models achieve comparable performance without retrieved context.

Saliency-Aware Steganography with a Hybrid AES and RSA with LSB Embedding

A new framework that combines hybrid encryption with saliency-based adaptive embedding to select the most effective regions for data concealment in cover images, based on the BossBase dataset is proposed.
