Center node: "towards functorial language games"
  Abstract: In categorical compositional semantics of natural language one studies functors from a category of grammatical derivations (such as a Lambek pregroup) to a semantic category (such as real vector spaces). We compositionally build game-theoretic semantics of sentences by taking the semantic category to be the category whose morphisms are open games. This requires some modifications to the grammar category to compensate for the failure of open games to form a compact closed category. We illustrate the theory using simple examples of Wittgenstein's language-games.

Connected through hyperedge HE-1 (induced by source paper "compositional deep learning"):
  with members:
    - "characterizing the invariances of learning algorithms using category theory"
    - "augmented cyclegan learning many to many mappings from unpaired data"
    - "a style based generator architecture for generative adversarial networks"
    - "translating and evolving towards a model of language change in discocat"
    - "morphisms of open games"
    - "unpaired image to image translation using cycle consistent adversarial networks"
    - "improved training of wasserstein gans"
    - "learning to learn by gradient descent by gradient descent"
