Joseph K. Bradley created SPARK-7423: ----------------------------------------
Summary: spark.ml Classifier predict should not convert vectors to dense format Key: SPARK-7423 URL: https://issues.apache.org/jira/browse/SPARK-7423 Project: Spark Issue Type: Improvement Components: ML Reporter: Joseph K. Bradley Priority: Minor spark.ml.classification.ClassificationModel and ProbabilisticClassificationModel both use DenseVector.argmax to implement prediction (computing the prediction from the rawPrediction or probability Vectors). It would be best to implement argmax for Vector and SparseVector and use Vector.argmax, rather than converting Vectors to dense format. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
