DLEstimator

class DLEstimator[T] extends DLEstimatorBase[DLEstimator[T], DLModel[T]] with DLParams[T]

DLEstimator helps to train a BigDL Model with the Spark ML Estimator/Transfomer pattern, thus Spark users can conveniently fit BigDL into Spark ML pipeline.

DLEstimator supports feature and label data in the format of Array[Double], Array[Float], org.apache.spark.mllib.linalg.{Vector, VectorUDT}, org.apache.spark.ml.linalg.{Vector, VectorUDT}, Double and Float.

User should specify the feature data dimensions and label data dimensions via the constructor parameters featureSize and labelSize respectively. Internally the feature and label data are converted to BigDL tensors, to further train a BigDL model efficiently.

For details usage, please refer to examples in package com.intel.analytics.bigdl.example.MLPipeline
