The training error may occur when there is insufficient data available to create a valid VML profile.
You will need to increase the number of files provided in the negative or positive sets to make an successful VML training profile.The recommended number of documents is 250 per training set. The minimum number of documents per training set is 50
Change the value of logging value from INFO to FINEST
For example: com.vontu.machinelearning.training.MLDTrainingLogHandler.level = FINEST
NOTE: For troubleshooting such issues you can increase the logging level in the MLDTrainingLogging.properties file found in the \Vontu\Protect\Config directory on the Enforce server and review the machinelearning_training_0_0.log found in the \Vontu\Protect\Logs directory:
Once troubleshooting is complete Symantec recommends to change the value from FINEST to INFO.
