Compact target-aware stability-based feature selection for cross-dataset wearable activity monitoring

Wearable activity-recognition models may lose reliability when transferred across participants, sensor placements, sampling rates, acquisition protocols, and activity definitions. This study evaluates a compact unsupervised target-aware feature-selection strategy for cross-dataset wearable activity monitoring under a p...

FEAM-Swin: A Lightweight Frequency Aware Swin Transformer for Efficient Hyperspectral Image Classification

: Hyperspectral image (HSI) classification requires models that can effectively capture long-range contextual dependencies while preserving fine-grained spectral–spatial variations under strict computational constraints. Recent transformer-based approaches, particularly Swin Transformers, have shown strong performance...
