Please predict whether this patent is acceptable.PATENT ABSTRACT: Systems, methods, and non-transitory computer-readable media can obtain a content item to be evaluated by a set of cascaded convolutional neural networks, the set of cascaded convolutional neural networks including at least a first convolutional neural network (CNN) and a second CNN. The content item can be provided to the first CNN as input, wherein an output of the first CNN includes data describing at least one region of interest in the content item and at least one first concept corresponding to the region of interest. The output of the first CNN can be provided to the second CNN as input, wherein an output of the second CNN includes data describing at least one second concept corresponding to the region of interest, the second concept being more accurate than the first concept.
