Function Documentation

gnn_criterion* gnn_weight_elimination_new (  gnn_criterion *    crit, double    nu, double    wp, gnn_node *    node )

This function builds a new gnn_weight_elimination regularizer for all gnn_weight : Affine / Linear Transform nodes contained in the given node node. Parameters: crit  A pointer to a gnn_weight_elimination criterion. nu  The regularization coefficient . wp  The scale factor . node  A pointer to a gnn_node. Returns: Returns a pointer to a gnn_weight_elimination if succeeded or NULL. Definition at line 273 of file gnn_weight_elimination.c.

gnn_criterion* gnn_weight_elimination_new_with_pbundle (  gnn_criterion *    crit, double    nu, double    wp, gnn_pbundle *    pb )

This function builds a new gnn_weight_elimination regularizer for all parameters contained in the given parameter bundle pb. Parameters: crit  A pointer to a gnn_weight_elimination criterion. nu  The regularization coefficient . wp  The scale parameter . pb  A gnn_pbundle. Returns: Returns a pointer to a gnn_weight_elimination if succeeded or NULL. Definition at line 361 of file gnn_weight_elimination.c.

gnn_criterion* gnn_weight_elimination_new_with_type (  gnn_criterion *    crit, double    nu, double    wp, gnn_node *    node, const char *    type )

This function builds a new gnn_weight_elimination regularizer for all parameters that pertain to nodes of type type contained in the given node node. Parameters: crit  A pointer to a gnn_weight_elimination criterion. nu  The regularization coefficient . wp  The scale parameter . node  A pointer to a gnn_node. type  A string containing the type. Returns: Returns a pointer to a gnn_weight_elimination if succeeded or NULL. Definition at line 316 of file gnn_weight_elimination.c.

int gnn_weight_elimination_prun (  gnn_criterion *    crit, double    th )

This function pruns the penalized parameters that fall below the given threshold th in magnitude. These are frozen to zero. Parameters: crit  A pointer to a gnn_weight_elimination criterion. th  The threshold for parameter pruning. Returns: Returns 0 if succeeded. Definition at line 551 of file gnn_weight_elimination.c.
