theano中apply节点和op节点的区别

Difference between apply node and op node in theano

这里是 Theano 初学者。我刚刚浏览了 deeplearning.net 上的图形结构部分,但我有疑问。

教程中指出,"Apply node represents the application of an op to some variables. It is important to draw the difference between the definition of a computation represented by an op and its application to some actual data which is represented by the apply node."

在 theano 中,通过首先创建一个函数并将适当的值插入 f() 来执行对数据的计算。 op 节点在哪里出现?

theano中的OP表示计算,如add、dot、convolution。并且我们通过 OP 来定义我们所有的作品,然后通过 theano.function() 将其构建到特定的图。看看here

Theano represents symbolic mathematical computations as graphs. These graphs are composed of interconnected Apply, Variable and Op nodes. Apply node represents the application of an op to some variables.

我不确定这是否能回答您的问题。让我知道是否仍然不清楚。
