Below is an example of a custom loss function for complex inputs, which you can use in your training loop: % dummy data numSamples = 100; numTimesteps = 10; numChannels = 2; realPart = randn(numSamples, numTimesteps, numChannels); ...

3.2 卷积层(Convolution Layer) 卷积层是CNN最重要的部分。它与传统全连接层不同,卷积层中每一个节点的输入只是上一层神经网络的一小块。卷积层被称为过滤器(filter)或者内核(kernel),Tensorflow的官方文档中称这个部分为过滤器(filter)。 【注意】在一个卷积层中,过滤器(filter)所处理的节点矩阵的长和宽都是由...

I got thoroughly nerd-sniped by this xkcd, leading me to wonder if you can use MATLAB to figure out the dice roll for any given (rational) probability. Well, obviously you can. The question is how. Answer: lots of permutation calculations and convolutions. In the original xkcd, the situa...
