   用于随机场的双保真 Karhunen-Loève 展开代理模型与主动学习方法

   提出双保真 Karhunen-Loève 展开代理模型（BF-KLE-AL），用 KLE 与多项式混沌展开（PCE）保持输入不确定性到输出标量场的显式映射，并以少量高保真（HF）仿真修正低保真（LF）模拟的系统偏差。

Current heat 5·Comparable peak 10（Oct 5）·Comparable change over 24 hours -50%

The trend compares only the same participants observed continuously; its range may be smaller than the current heat count. Move or click on the chart to inspect hourly heat; use the left and right arrow keys to switch.
