Weak Signal Problem
Performance
WS-Net integrates a multi-resolution wavelet encoder, a dual-branch backbone (Mamba state-space + Weak Signal Attention), and a sparsity-aware decoder with KL-divergence regularization. This combination specifically targets and enhances weak spectral signals, which are often suppressed by conventional methods.
Weak spectral responses from low-reflectance materials or trace elements are prone to 'weak signal collapse'—underestimation or complete omission—due to dominant endmembers and noise. WS-Net is explicitly designed to counteract this by selectively amplifying these subtle cues.
Across synthetic and real-world datasets (Samson, Apex), WS-Net consistently outperforms six state-of-the-art baselines. It achieves significant reductions in RMSE and SAD, particularly for weak endmembers and under low-SNR conditions, demonstrating superior stability and accuracy.

Sparsity-Aware Decoder
| Feature | WS-Net Approach | Typical DL Approach |
|---|---|---|
| Weak Signal Handling | Explicit enhancement via WSA, multi-resolution fusion | Often diluted by global averaging/pooling |
| Long-range Dependencies | Mamba SSM (efficient) + Transformer (global context) | CNNs (local) or standard Transformers (costly, less focused) |
| Abundance Constraints | Softmax + KL-divergence for separability | Basic ANC/ASC, less spectral disentanglement |
| Robustness to Noise | High due to wavelet denoising and adaptive fusion | Variable, often degraded under low-SNR |
Real-World Impact: Apex Dataset
On the challenging Apex dataset, WS-Net demonstrated superior performance, achieving the lowest mean RMSE (0.0460) and SAD (0.0740). Crucially, it showed the largest gains on weak-signal classes such as Road and Water, outperforming baselines by up to 31% RMSE reduction on Road and maintaining best SAD across all endmembers. This highlights WS-Net's practical utility in complex, real-world remote sensing applications where subtle features are critical.
