Quantum simulations of materials on near-term quantum computers

no code implementations25 Feb 2020 He Ma, Marco Govoni, Giulia Galli

Quantum computers hold promise to enable efficient simulations of the properties of molecules and materials; however, at present they only permit ab initio calculations of a few atoms, due to a limited number of qubits.

Quantitatively Evaluating GANs With Divergences Proposed for Training

no code implementations ICLR 2018 Daniel Jiwoong Im, He Ma, Graham Taylor, Kristin Branson

Generative adversarial networks (GANs) have been extremely effective in approximating complex distributions of high-dimensional, input data samples, and substantial progress has been made in understanding and improving GAN performance in terms of both theory and application.

Generative Adversarial Parallelization

no code implementations13 Dec 2016 Daniel Jiwoong Im, He Ma, Chris Dongjoo Kim, Graham Taylor

Generative Adversarial Networks have become one of the most studied frameworks for unsupervised learning due to their intuitive formulation.

Theano-MPI: a Theano-based Distributed Training Framework

1 code implementation26 May 2016 He Ma, Fei Mao, Graham W. Taylor

We develop a scalable and extendable training framework that can utilize GPUs across nodes in a cluster and accelerate the training of deep learning models based on data parallelism.
