Hi Andrew Thanks for your response. Could you give some web links you mentioned in email (See the section on the website about classifiers for more about the available methods. There is also a Jira ticket about incorporating some of Ted's work which if you're interested you could work on.).

See the section on the website about classifiers for more about the available methods. There is also a Jira ticket about incorporating some of Ted's work which if you're interested you could work on.
