    "title": "Generalizing Outside the Training Set:When Can Neural Networks Learn Identity Effects?",
    "subtitle": null,
    "abstract": "Often in language and other areas of cognition, whether twocomponents of an object are identical or not determine whetherit is well formed. We call such constraints identity effects.When developing a system to learn well-formedness from ex-amples, it is easy enough to build in an identify effect. But canidentity effects be learned from the data without explicit guid-ance? We provide a simple framework in which we can rig-orously prove that algorithms satisfying simple criteria cannotmake the correct inference. We then show that a broad classof algorithms including deep neural networks with standardarchitecture and training with backpropagation satisfy our cri-teria, dependent on the encoding of inputs. Finally, we demon-strate our theory with computational experiments in which weexplore the effect of different input encodings on the ability ofalgorithms to generalize to novel inputs.",
