Package org.apache.sysds.runtime.compress.plan

Class NaivePlanEncode

java.lang.Object

org.apache.sysds.runtime.compress.plan.NaivePlanEncode

All Implemented Interfaces:

IPlanEncode

public class NaivePlanEncode
extends Object
implements IPlanEncode

Naive implementation of encoding based on a plan. This does not reuse plans across groups, and does not smartly extract encodings.
