Learn Models using ML Pipeline in Spark. 2.2.1.2 Specify parameters The next step is setting up parameters for ML algorithms, LogisticRegression. We give 10 for maxIter (Max Iteration) and 0.01 for regParam (Regularization parameter) For detail, see reference [7] After running the above codes in Spark shell, you will see a bunch of parameters you specified, e.g. maxIter and regParam, and can specify or change, aggregationDepth and etc. 2.2.1.3 Learn model Now it’s time to learn mode wi...
