Re: Print Decision Tree Models
Which Spark version are you using? It works in 1.1.0 but not in 1.0.0. -Xiangrui On Wed, Oct 1, 2014 at 2:13 PM, Jimmy McErlain wrote: > So I am trying to print the model output from MLlib however I am only > getting things like the following: > > org.apache.spark.mllib.tree.model.DecisionTreeModel@1120c600 > > 0.17171527904439082 > 0.8282847209556092 > 5273125.0 > 2.5435412E7 > > > from the following code: > > val trainErr = labelAndPreds.filter(r => r._1 != r._2).count.toDouble / > cleanedData2.count > val trainSucc = labelAndPreds.filter(r => r._1 == r._2).count.toDouble > / cleanedData2.count > val trainErrCount = labelAndPreds.filter(r => r._1 != > r._2).count.toDouble > val trainSuccCount = labelAndPreds.filter(r => r._1 == > r._2).count.toDouble > > print(model) > println(trainErr) > println(trainSucc) > println(trainErrCount) > println(trainSuccCount) > > > I have also tried the following: > > val model_string = model.toString() > print(model_string) > > > And I still do not get the model to print but where it resides in memory. > > > Thanks, > > J > > > > > > > > *JIMMY MCERLAIN* > > DATA SCIENTIST (NERD) > > *. . . . . . . . . . . . . . . . . .* > > > *IF WE CAN’T DOUBLE YOUR SALES,* > > > > *ONE OF US IS IN THE WRONG BUSINESS.* > > *E*: ji...@sellpoints.com > > *M*: *510.303.7751 <510.303.7751>* > ᐧ >
Print Decision Tree Models
So I am trying to print the model output from MLlib however I am only getting things like the following: org.apache.spark.mllib.tree.model.DecisionTreeModel@1120c600 0.17171527904439082 0.8282847209556092 5273125.0 2.5435412E7 from the following code: val trainErr = labelAndPreds.filter(r => r._1 != r._2).count.toDouble / cleanedData2.count val trainSucc = labelAndPreds.filter(r => r._1 == r._2).count.toDouble / cleanedData2.count val trainErrCount = labelAndPreds.filter(r => r._1 != r._2).count.toDouble val trainSuccCount = labelAndPreds.filter(r => r._1 == r._2).count.toDouble print(model) println(trainErr) println(trainSucc) println(trainErrCount) println(trainSuccCount) I have also tried the following: val model_string = model.toString() print(model_string) And I still do not get the model to print but where it resides in memory.
