WHAT IS THIS NOW..?

That's the trained models toString. It's very long because the toString encodes the provenance (as mentioned in the tutorials), it's an ensemble and each model in the ensemble captures the dataset information.

There isn't an error message in that output. Is there something else that makes you think it errored out? A stack trace or an exception?

If you want a way to reference a model via a string you can use setName and getName to tag it with something short and memorable. The default name is based on the trainer, here it's "random-forest-ensemble".

no my main question is how can i get my crossvalidation scores i cant find it.i know mode has been trained on trained data in 10 folds.but wheres the score how to get it?

You can use EvaluationAggregator.summarize() to produce a Map from metric to DescriptiveStats which give the mean, variance, max and min of the metric. Or summarize a specific metric by passing in a getter function.

nikkisingh111333 commented 4 years ago

i got it i m calling summarize but i m getting class cast exception here is my stack trace with code: MY CODE: LabelEvaluator eva=new LabelEvaluator(); CrossValidation cv=new CrossValidation(cart,trainData,eva,10); List ev=cv.evaluate(); EvaluationAggregator.summarize(ev); AND I M GETTING THIS: Exception in thread "main" java.lang.ClassCastException: com.oracle.labs.mlrg.olcut.util.Pair cannot be cast to org.tribuo.evaluation.Evaluation at org.tribuo.evaluation.EvaluationAggregator.summarize(EvaluationAggregator.java:166) at MachineLearningWithTRIBUO.TribuoML.DecisionTree(TribuoML.java:79) at MachineLearningWithTRIBUO.TribuoML.main(TribuoML.java:182) There are other bunch of summarize api versions but dont understand where to pass what i have tried everything. whats the matter ?

Craigacp commented 4 years ago

evaluate() returns a List<Pair<Evaluation,Model<T>>>. You need to pass in a List<Evaluation> to the aggregator. So make a new list and add the first element of each pair to it.

nikkisingh111333 commented 4 years ago

thanks i got it..hey adam can you please suggest me any good data preparation tool i m really tired from finding a good one f=currently using tableau .not only limited features are there.

I don't have any specific recommendations on data prep, we tend to use a complex RowProcessor or use single use scripts for many of our tasks as it all depends where the data is and how much transformation it needs.
