std::vector< chunk_info > | batch_info |
Defines the output of a data_iterator.
Definition at line 76 of file ac_data_iterator.hpp.
std::vector<chunk_info> turi::activity_classification::data_iterator::batch::batch_info |
Metadata for each valid (non-padded) row in the batch.
The size of this vector is at most requested_batch_size. The info at index i
describes the array at features[i]
.
Definition at line 134 of file ac_data_iterator.hpp.
neural_net::shared_float_array turi::activity_classification::data_iterator::batch::features |
An array with shape: (requested_batch_size, 1, prediction_window * predictions_in_chunk, num_feature_columns)
Each row is a chunk of feature values from one session.
Definition at line 97 of file ac_data_iterator.hpp.
neural_net::shared_float_array turi::activity_classification::data_iterator::batch::labels |
An array with shape: (requested_batch_size, 1, predictions_in_chunk, 1)
Each row is the sequence of class label (indices) from one chunk (labels picked after majority voting).
If no target was specified, then this value is default constructed.
Definition at line 107 of file ac_data_iterator.hpp.
neural_net::shared_float_array turi::activity_classification::data_iterator::batch::labels_per_row |
An array with shape: (requested_batch_size, 1, prediction_window * predictions_in_chunk, 1)
Each row is the sequence of raw class labels (indices) for each individual sample.
Definition at line 126 of file ac_data_iterator.hpp.
neural_net::shared_float_array turi::activity_classification::data_iterator::batch::weights |
An array with shape: (requested_batch_size, 1, predictions_in_chunk, 1)
Each row is a sequence of 0 or 1 values indicating whether the corresponding label is padding (0) or refers to actual data (1).
If no target was specified, then this value is default constructed.
