I am working with Watson Visual Recognition and have successfully created a custom classifier.
I notice the build in default classifier can return a hierarchy eg: Animals/Dog, But how to create a custom classifier return response contains "type_hierarchy" such as default classifier ?
It may be necessary to train a custom classifier with more positive class and negative class or it is possibly due to me being on the trial version ?!!
The multi level hierarchy in the default classifier is a special feature of that classifier. You cannot create a hierarchy within a custom classifier. This is true of both free and paid plans. However, in a custom classifier, you get to specify the name of each class, so you could include hierarchical information in each class name, for example "animals_dog_beagle" could be a class name.
Note that classes within a classifier should be mutually exclusive, since the learner uses the positive examples from one class as the negative examples of the others. (Along with any explicitly given negative examples)
