thawWeights [-group <group-list> | -unit <unit-list> | -type <link-type>]
This resumes weight changes on frozen links of the specified type during training. If no type is specified, all link types are affected.
If a group list or unit list is given, only links into those groups or units are affected. Otherwise, all links of the appropriate type are affected.
Selective freezing or thawing can be used to load weights into specific parts of the network using the loadWeights command.
To stop updates to bias links to the output layer:
lens> thawWeights -g output -t bias
