Examples of QRLastStep

org.apache.mahout.math.hadoop.stochasticsvd.qr.QRLastStep
Second/last step of QR iterations. Takes input of qtHats and rHats and provides iterator to pull ready rows of final Q.

Examples of org.apache.mahout.math.hadoop.stochasticsvd.qr.QRLastStep


      closeables.addFirst(rhatInput);
      outputs = new MultipleOutputs(new JobConf(context.getConfiguration()));
      closeables.addFirst(new IOUtils.MultipleOutputsCloseableAdapter(outputs));


      qr = new QRLastStep(qhatInput, rhatInput, blockNum);
      closeables.addFirst(qr);
      /*
       * it's so happens that current QRLastStep's implementation preloads R
       * sequence into memory in the constructor so it's ok to close rhat input
       * now.
