brainpy.nn.nodes.ANN.BatchNorm1d
brainpy.nn.nodes.ANN.BatchNorm1d#
- class brainpy.nn.nodes.ANN.BatchNorm1d(axis=(0, 1), **kwargs)[source]#
1-D batch normalization. The data should be of (b, l, c), where b is the batch dimension, l is the layer dimension, and c is the channel dimension, or of ‘(b, c)’.
- Parameters
axis (int, tuple, list) – axes where the data will be normalized. The feature (channel) axis should be excluded.
epsilon (float) – a value added to the denominator for numerical stability. Default: 1e-5
use_bias (bool) – whether to translate data in refactoring. Default: True
use_scale (bool) – whether to scale data in refactoring. Default: True
beta_init (brainpy.init.Initializer) – an initializer generating the original translation matrix
gamma_init (brainpy.init.Initializer) – an initializer generating the original scaling matrix
