How valuable would an auto custom classifier be for you? When I say auto, I mean you give the class name and a short text description of what it should look like. You'll be able to edit the subclasses manually or via textual feedback. The final classifier would have several sub-categories; you'll get multi-label presence/absence for sub-categories and reasoning. Would you be interested in text, images or both? And what would you be willing to pay for it?
