Class FrozenVertex

java.lang.Object

org.deeplearning4j.nn.graph.vertex.BaseWrapperVertex

org.deeplearning4j.nn.graph.vertex.impl.FrozenVertex

All Implemented Interfaces:

Serializable, GraphVertex

public class FrozenVertex
extends BaseWrapperVertex

FrozenVertex is used for the purposes of transfer learning A frozen layers wraps another DL4J GraphVertex within it. During backprop, the FrozenVertex is skipped, and any parameters are not be updated.
