AI can already dream up imaginary celebrities, so perhaps it can help the Army imagine revolutionary new engine parts or aircraft, too. DARPA wants entrants to rethink the way complex components are designed by combining recent advances in machine learning with fundamental tenets of math and engineering. AI is increasingly being used to imagine new things, from celebrity faces to clothing (see "The GANfather: The man who's given machines the gift of imagination"). The systems being used to conjure up new ideas are still in their early stages, but they show a path forward. Machine learning is also already used in some areas of design and engineering, but the DARPA project aims to apply it more broadly, and to the crucial task of determining function and form.
