Data Sets

Currently DeepOBS includes nine different data sets. Each data set inherits from the same base class with the following signature.

class deepobs.tensorflow.datasets.dataset.DataSet(batch_size)[source]

Base class for DeepOBS data sets.

Parameters:batch_size (int) -- The mini-batch size to use.
batch

A tuple of tensors, yielding batches of data from the dataset. Executing these tensors raises a tf.errors.OutOfRangeError after one epoch.

train_init_op

A tensorflow operation initializing the dataset for the training phase.

train_eval_init_op

A tensorflow operation initializing the testproblem for evaluating on training data.

test_init_op

A tensorflow operation initializing the testproblem for evaluating on test data.

phase

A string-value tf.Variable that is set to train, train_eval or test, depending on the current phase. This can be used by testproblems to adapt their behavior to this phase.
