Get Classifier Sample Information (G Dataflow)

Last Modified: October 25, 2017

Retrieves the thumbnail image and class label of the sample at the specified index.

connector_pane_image
datatype_icon

classifier session in

Reference to the classifier session on which the node operates.

datatype_icon

thumbnail image in

Reference to the image that will store the thumbnail image of the sample specified by sample index.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

sample index

Index of a sample in the classifier session.

The samples are indexed in the order in which they were added to the session, starting with 0. Set this parameter to -1 to get only the number of samples value.

datatype_icon

feature vector

Vector entered in the Add Custom Classifier Sample node.

If the session referenced by classifier session in is not a custom session, feature vector is empty.

datatype_icon

classifier session out

Reference to the classifier session the node creates.

datatype_icon

thumbnail image out

Reference to the image that stores the thumbnail image of the sample specified by sample index.

datatype_icon

class

Class to which the sample specified by sample index belongs.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

number of samples

Total number of samples in the classifier session.
