Detailed Description

This structure holds the information for a node.

• type: This is a string that holds the name of the node's type. It allows to check a node's type at runtime.
• n: The size of the input vector .
• m: The size of the output vector .
• whnd: The node's own parameter handle.
• whnds: This is a NULL-terminated array of gnn_whnd parameter handles. Every handle appears at most 1 time (i.e. there aren't any handles pointing to the same parameters).
• x: A pointer to the last evaluated input vector .
• destroy: A pointer to the node's destructor, which is invoked when called the gnn_node_destroy function. It should free the additional memory allocated for the specific node type.
• f: A pointer to the evaluation function, which is called upon execution of gnn_node_eval_f.
• dw: A pointer to the gradient with respect to its parameters , which is called upon execution of gnn_node_eval_dw.
• dx: A pointer to the gradient with respect to its inputs , which is called upon execution of gnn_node_eval_dw.
• super: A pointer to it's parent node (super), or NULL if the node is the root of the function tree.
• nsub: The number of children (subnodes) of the current node.
• sub: An array of pointer of size (nsub) with pointers to the current node's subnodes.
