Method Detail

initialize

public Shape[] initialize(NDManager manager,
                          DataType dataType,
                          Shape... inputShapes)

Initializes the parameters of the block. This method must be called before calling `forward`.

Parameters:

manager - the NDManager to initialize the parameters

dataType - the datatype of the parameters

inputShapes - the shapes of the inputs to the block

Returns:

the shapes of the outputs of the block

getChildren

public final BlockList getChildren()

Returns a list of all the children of the block.

Returns:

the list of child blocks

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
