Member Function Documentation

class_labels()

const flex_list& turi::drawing_classifier::simple_data_iterator::class_labels ( ) const

inlineoverridevirtual

Returns a sorted list of the unique "label" values found in the target.

Implements turi::drawing_classifier::data_iterator.

Definition at line 159 of file dc_data_iterator.hpp.

has_next_batch()

bool turi::drawing_classifier::simple_data_iterator::has_next_batch ( )

overridevirtual

Returns true if and only if the next call to next_batch will return a batch with size greater than 0.

Implements turi::drawing_classifier::data_iterator.

next_batch()

batch turi::drawing_classifier::simple_data_iterator::next_batch ( size_t  batch_size )

overridevirtual

Returns a vector whose size is equal to batch_size.

If repeat was set in the parameters, then the iterator will cycle indefinitely through the SFrame over and over. Otherwise, the last non-empty batch may contain fewer than batch_size elements, and every batch after that will be empty.

Implements turi::drawing_classifier::data_iterator.

reset()

void turi::drawing_classifier::simple_data_iterator::reset ( )

overridevirtual

Begins a fresh traversal of the dataset.

Implements turi::drawing_classifier::data_iterator.
