This file provides information on how to perform data exploration, modeling, and scoring in Spark.0 clusters.
Specifically, we plot the frequency of passenger counts in taxi trips, the frequency of tip amounts, and how tips vary by payment amount and type.This consists of performing an exhaustive search through the values a specified subset of the hyperparameter space for a learning algorithm.Determinants of lumbar disc degeneration.Spine (Phila Pa 1976).Optional water immersion cap is available to be used as a water immersion objective.ElasticNetParam, (0.25,0.75).build # define pipeline # simply THE model here, without transformations pipeline Pipeline(stageslr) # define CV with parameter sweep cv CrossValidator(estimator lr, estimatorParamMapsparamGrid, numFolds3) # convert TO data frame, AS crossvalidator WON'T RUN ON rdds trainDataFrame eateDataFrame(oneHottrainreg, "features "label # train with cross-validation cv_model.Zeros(numModels # begin CV with parameter sweep for i in range(nFolds # Create training and x-validation sets validateLB i * h validateUB (i 1) * h condition (trainData"rand" validateLB) (trainData"rand" validateUB) validation lter(condition) # Create LabeledPoints from data-frames if i 0: trainCVLabPt.Note Cross-validation with parameter sweeping using custom code is provided in the appendix.The default container attached to the Spark cluster can be referenced using a path beginning with: "wasb.GBTs are used for regression and classification and can handle categorical features, do not require feature scaling, and are able to capture non-linearities and feature interactions.Suited for clinical inspection and student training.Features bel) # instantiate metrics object metrics # area under precision-recall curve print Area under PR s" eaUnderPR) # area under ROC curve print Area under ROC s" eaUnderROC) metrics # overall statistics precision ecision recall call f1Score easure print Summary Stats print Precision s".Logistic regression with lbfgs or "logit" regression, is a regression model that can be used when the dependent variable is categorical to do data classification.
