I couldn't find the classification.SVM class.
- Most probably the command is something of the order of:
- bin/spark-submit --class
org.apache.spark.examples.mllib.BinaryClassification
examples/target/scala-*/spark-examples-*.jar --algorithm SVM train.csv
- For more details try
- ./bin/run-example mllib.BinaryClassification <spark url>
- Usage: BinaryClassification [options] <input>
- --numIterations <value> number of iterations
- --stepSize <value> initial step size, default: 1.0
- --algorithm <value> algorithm (SVM,LR), default: LR
- --regType <value> regularization type (L1,L2),
default: L2
- --regParam <value> regularization parameter, default:
0.1
- <input> input paths to labeled examples in LIBSVM
format
HTH.
Cheers
<k/>
P.S: I am using 1.0.0 rc10. Even for earlier release, just run the
classification class and it will tell you what the parameters are. Most
probably SVM is an algorithm parameter not a class by itself.
