Graph

abstract class Graph[T] extends Container[Activity, Activity, T] with MklInt8Convertible

A graph container. The modules in the container are connected as a directed Graph. Each module can output one tensor or multiple tensors(as table). The edges between modules in the graph define how these tensors are passed. For example, if a module outputs two tensors, you can pass these two tensors together to its following module, or pass only one of them to its following module. If a tensor in the module output is connected to multiple modules, in the back propagation, the gradients from multiple connection will be accumulated. If multiple edges point to one module, the tensors from these edges will be stack as a table, then pass to that module. In the back propagation, the gradients will be splited based on how the input tensors stack.

The graph container has multiple inputs and multiple outputs. The order of the input tensors should be same with the order of the input nodes when you construct the graph container. In the back propagation, the order of the gradients tensors should be the same with the order of the output nodes.

If there's one output, the module output is a tensor. If there're multiple outputs, the module output is a table, which is actually an sequence of tensor. The order of the output tensors is same with the order of the output modules.

All inputs should be able to connect to outputs through some paths in the graph. It is allowed that some successors of the inputs node are not connect to outputs. If so, these nodes will be excluded in the computation.

    2. If there're two parameters, the first parameter is named as "weight", the first gradient is named as "gradWeight"; the second parameter is named as "bias", the seconcd gradient is named as "gradBias"

    3. If there're more parameters, the weight is named as "weight" with a seq number as suffix, the gradient is named as "gradient" with a seq number as suffix
