Spatial 1D version of Dropout.
This version performs the same function as Dropout, however it drops entire
1D feature maps instead of individual elements. If adjacent frames within
feature maps are strongly correlated (as is normally the case in early
convolution layers) then regular dropout will not regularize the activations
and will otherwise just result in an effective learning rate decrease. In
this case, layer_spatial_dropout_1d will help promote independence between
feature maps and should be used instead.
layer_spatial_dropout_1d(object, rate, batch_size = NULL, name = NULL,
trainable = NULL, weights = NULL)Arguments
| object | Model or layer object |
| rate | float between 0 and 1. Fraction of the input units to drop. |
| batch_size | Fixed batch size for layer |
| name | An optional name string for the layer. Should be unique in a model (do not reuse the same name twice). It will be autogenerated if it isn't provided. |
| trainable | Whether the layer weights will be updated during training. |
| weights | Initial weights for layer. |
Input shape
3D tensor with shape: (samples, timesteps, channels)
Output shape
Same as input
