Hi,
I am trying to use apache spark's decision tree classifier. I am
trying to implement the method found in
https://spark.apache.org/docs/1.5.1/ml-decision-tree.html 's
classification example. I found the dataset at
https://github.com/apache/spark/blob/master/data/mllib/sample_libsvm_data.txt
and I have some trouble understanding its format. Is the first column
the label? Why are there indices and a colon in front of other number
values and what do the indices represent?
Lastly, how do I print out a prediction given new test data?
Thanks,
Serena Sian Yuan
