machine learning - Prediction with LightSide does not work -


i working machine learning workbench lightside ma-thesis. have trained models, use trained model predict new data. however, when try so, system stops after few seconds, pop-up message "prediction been stopped" , no hint on why. happens different data sets, algorithms used training...

has encountered same problem , found solution it? thank :)

edit: tried export feature table weka , train models there, weka gets lost in endless training loop, assume has built-in feature unigram use form lightside. still not closer predicting on new data...

edit ii: lightside throws error saying 1 feature not part of model, when in fact is

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
