gnn_dataset_view : A view for datasets.
[gnn_dataset : Datasets for Training.]

Detailed Description

The gnn_dataset_view : A view for datasets. is a gnn_dataset : Datasets for Training. that provides a transparent view for a slice of a ref gnn_dataset, acting as it where a normal dataset.

A gnn_subset can be built upon an arbitrary gnn_dataset : Datasets for Training.. It provides a view of a slice of the underlying dataset. For example, a subrange of another dataset can be described with a view, or two views can be made which provide access to the even and odd patterns of a dataset.

A view consist of a starting index , a stride and a the number of patterns . So, the ith-pattern of the dataset view corresponds to the underlying dataset's pattern with index

When building a gnn_dataset_view : A view for datasets. upon a given gnn_dataset : Datasets for Training., the gnn_dataset_view : A view for datasets. structure won't own the source-dataset. That means that if you destroy the gnn_dataset_view : A view for datasets. structure, the underlying gnn_dataset : Datasets for Training. won't be destroyed. It should be destroyed manually.

Function Documentation

void gnn_dataset_view_destroy (  gnn_dataset *    set )  [static]

This is the gnn_dataset_view : A view for datasets. destroy function. Parameters: set  A pointer to a gnn_dataset_view : A view for datasets. dataset. Definition at line 154 of file gnn_dataset_view.c.

int gnn_dataset_view_get (  gnn_dataset *    set, size_t    k, gsl_vector **    x, gsl_vector **    t, double *    p )  [static]

This function is returns the k-th pattern in the dataset view. Parameters: set  A pointer to a gnn_dataset_view : A view for datasets.. k  The index of the pattern to be retrieved. x  A reference for the input pattern. t  A reference for the output pattern. p  A pointer to a double for the pattern weight.
