In this tutorial, we build a safety-critical reinforcement learning pipeline that learns entirely from fixed, offline data rather than live exploration. We design a custom environment, generate a ...

Abstract: Due to the inherent $\pi $ -phase constraint in phase unwrapping algorithms, the dynamic strain range of phase-sensitive optical time domain reflectometry ($\Phi $ -OTDR) is significantly ...

As a novel type of reconfigurable metamaterial, metasurfaces can manipulate incident waves in multiple dimensions, including energy, space, and phase, effectively reducing the adversary's detection ...
