Learning Unitaries by Gradient Descent

no code implementations31 Jan 2020 Bobak Toussi Kiani, Seth Lloyd, Reevu Maity

We study the hardness of learning unitary transformations in $U(d)$ via gradient descent on time parameters of alternating operator sequences.

Random deep neural networks are biased towards simple functions

1 code implementation NeurIPS 2019 Giacomo De Palma, Bobak Toussi Kiani, Seth Lloyd

We prove that the binary classifiers of bit strings generated by random wide deep neural networks with ReLU activation function are biased towards simple functions.
