	Component ()
virtual std::string	Type () const =0
virtual int32	Index () const
	Returns the index in the sequence of layers in the neural net; intended only to be used in debugging information. More...

void	Propagate (const ChunkInfo &in_info, const ChunkInfo &out_info, const CuMatrixBase< BaseFloat > &in, CuMatrix< BaseFloat > *out) const
	A non-virtual propagate function that first resizes output if necessary. More...

virtual Component *	Copy () const =0
	Copy component (deep copy). More...
