Specification of the hyperparameter space for the model B family. Minibatch size and dropout rate are quantified to avoid an exhaustive search.

Model	Hyperparameter	Original value range	Quantified values
B1	Minibatch size	{1-infinity}	{32, 64, 128, 256, 512}
B2	Batch normalization	{on, off}	{on, off}
B3	Weight normalization	{on, off}	{on, off}
B4	Dropout rate	{0-1}	{0, 0.1, 0.2, 0.3, 0.4, 0.5}
