Nick Pentreath commented on SPARK-3903: --------------------------------------- I think given the move to DataFrames, and that we can load {{libsvm}} in DF, this can be closed? > Create general data loading method for LabeledPoints > ---------------------------------------------------- > > Key: SPARK-3903 > URL: https://issues.apache.org/jira/browse/SPARK-3903 > Project: Spark > Issue Type: Improvement > Components: ML > Affects Versions: 1.3.0 > Reporter: Joseph K. Bradley > Priority: Minor > > Proposal: Provide a more general data loading function for LabeledPoints. > * load multiple data files (e.g., train + test), and ensure they have the > same number of features (determined based on a scan of the data) > * use same function for multiple input formats > Proposed function format (in MLUtils), with default parameters: > {code} > def loadLabeledPointsFiles( > sc: SparkContext, > paths: Seq[String], > numFeatures = -1, > vectorFormat = "auto", > numPartitions = sc.defaultMinPartitions): Seq[RDD[LabeledPoint]] > {code} > About the parameters: > * paths: list of paths to data files or folders with data files > * vectorFormat options: dense/sparse/auto > * numFeatures, numPartitions: same behavior as loadLibSVMFile > Return value: Order of RDDs follows the order of the paths. > Note: This is named differently from loadLabeledPoints for 2 reasons: > * different argument order (following loadLibSVMFile) > * different return type -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
