An optimized unsupervised learning model for optical network unit placement in FiWi networks

A key challenge in developing fiber–wireless (FiWi) access networks is determining the optimal positions of optical network units (ONUs) to maximize network performance and minimize development costs. This paper introduces backtracking search-based weighted fuzzy C-means (BWFCM),...

Attention driven reinforcement guided U Net for reliable SAR image segmentation with uncertainty estimation

Synthetic Aperture Radar (SAR) imagery is widely used for flood monitoring, oil spill detection, and coastal mapping. However, automatic SAR image segmentation remains challenging due to speckle noise, low signal-to-clutter ratio, and ambiguous object boundaries. To address these...
