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.
