Constrains the weights incident to each hidden unit to have unit norm.
Source:R/constraints.R
constraint_unitnorm.RdConstrains the weights incident to each hidden unit to have unit norm.
Arguments
- axis
integer, axis along which to calculate weight norms. For instance, in a
Denselayer the weight matrix has shape(input_dim, output_dim), setaxisto0to constrain each weight vector of length(input_dim,). In aConv2Dlayer withdata_format = "channels_last", the weight tensor has shape(rows, cols, input_depth, output_depth), setaxisto[0, 1, 2]to constrain the weights of each filter tensor of size(rows, cols, input_depth).
Value
A Constraint instance, a callable that can be passed to layer
constructors or used directly by calling it with tensors.
