We firstly investigate the stability of the GRP scheme and find that it might be entropy unstable when the shock wave is generated. By adding an artificial viscosity we propose a new stabilized GRP scheme. Under the assumption that numerical solutions are uniformly bounded, we prove consistency ...
训练集:( Find the optimal values of in the training phase)用来训练出来神经网络的基本参数 验证集:( Find the optimal values of in the validation phase. )用来训练出来神经网络中的超参数,例如每层神经网络的个数以及深度(一般可用可不用) 测试集:( Test the performance of the network on unseen data...
更加容易收敛,相比一般随机序列,QMC只需要1/4模拟路径数;其次使用并行算法(比如GPU运算)生成随机序列...
(10) 输出'Alex Li', 将\t转换成多长的空格 name.find('A') 查找A,找到返回其索引, 找不到返回-1 format : >>> msg = "my name is {}, and age is {}" >>> msg.format("alex",22) 'my name is alex, and age is 22' >>> msg = "my name is {1}, and age is {0}" >>> ...
只用MC写过雪球的定价模型,印象里对于路径依赖型的奇异期权MC更直观,FD更适用于给美式这种具有提前支付...

We find that users want to compare expressions on multiple input ranges, integrate and guide various rewriting tools, and understand where errors come from. We organize this investigation's results into a three-stage workflow and implement that workflow in a new, extensible workbench dubbed Odyssey...
