I am trying to use the Clarifai API to recognize certain concepts in a scene. The first place where I will be debuting this device will be at the Science Fair where the judges will most likely want to test this product by making it recognize other products. When trying to see whether the API could detect posters or banners of any kind (even trifolds!). I am using the general model and I want to add a few concepts to the model so it could detect the science fair posters around me. Is there any possible way to add concepts to the general model. Any help would be greatly appreciated.
