Among all stereo matching methods End‐to‐End (E2E) learning methods show that they can achieve the lowest and most frequent minimum errors, however, their performance drastically changes across different test‐sites, which indicates poor generalisation capabilities.

PINN-type algorithm for shock capturing of hyperbolic equations(双曲型方程激波捕捉的物理信息神经网络(PINN)算法)
双曲型方程的数值求解算法研究一直是偏微分方程研究的热点,其中,双曲型方程的间断捕捉是难点。受物理信息神经网络(physics-informed neural networks,PINN)启发,构造了改进的PINN算法,近似求解双曲型方程的间断问题。将坐标构造的数据集作为神经网络的输入,将PINN算法中的损失函数作为训练输出值与参考解(基于细网格的熵相容格式数据)或准确解的误差值,通过网络优化,最小化损失函数,得到最优网络参数。最后用数值算例验证了算法的可行性,数值结果表明,本文算法能捕捉激波,分辨率高 ...
