Examples with CentralMoment org.apache.sysml.lops.CentralMoment used on opensource projects

Example 1 with CentralMoment

use of org.apache.sysml.lops.CentralMoment in project incubator-systemml by apache.

the class BinaryOp method constructLopsCentralMoment.

private void constructLopsCentralMoment(ExecType et) throws HopsException, LopsException {
    // The output data type is a SCALAR if central moment 
    // gets computed in CP/SPARK, and it will be MATRIX otherwise.
    DataType dt = (et == ExecType.MR ? DataType.MATRIX : DataType.SCALAR);
    CentralMoment cm = new CentralMoment(getInput().get(0).constructLops(), getInput().get(1).constructLops(), dt, getValueType(), et);
    setLineNumbers(cm);
    if (et == ExecType.MR) {
        cm.getOutputParameters().setDimensions(1, 1, 0, 0, -1);
        UnaryCP unary1 = new UnaryCP(cm, HopsOpOp1LopsUS.get(OpOp1.CAST_AS_SCALAR), getDataType(), getValueType());
        unary1.getOutputParameters().setDimensions(0, 0, 0, 0, -1);
        setLineNumbers(unary1);
        setLops(unary1);
    } else {
