Fin stabilizers governed by proportional-integral-derivative (PID) controllers dominate active ship roll reduction, yet their performance depends critically on gain tuning under nonlinear hydrodynamics and time-varying sea states. This paper proposes an Improved Secretary Bird Op...

A causal semantic intervention framework for few-shot SAR-ATR
Few-shot synthetic aperture radar automatic target recognition (SAR-ATR) remains challenging due to limited labelled samples. Most existing few-shot SAR-ATR methods recognize targets merely from visual features, and their recognition process is easily affected by biases introduce...
