Spontaneous Symmetry Breaking in Neural Networks
Ricky Fok, Aijun An, Xiaogang Wang
We propose a framework to understand the unprecedented performance and robustness of deep neural networks using field theory. Correlations between the weights within the same layer…
Optimization assisted MCMC
Ricky Fok, Aijun An, Xiaogang Wang
Markov Chain Monte Carlo (MCMC) sampling methods are widely used but often encounter either slow convergence or biased sampling when applied to multimodal high dimensional distribu…
Geodesic and Contour Optimization Using Conformal Mapping
Ricky Fok, Aijun An, Xiaogong Wang
We propose a novel optimization algorithm for continuous functions using geodesics and contours under conformal mapping.The algorithm can find multiple optima by first following a…
Distinguishing `Higgs' Spin Hypotheses using gamma gamma and WW* Decays
John Ellis, Ricky Fok, Dae Sung Hwang +2
The new particle X recently discovered by the ATLAS and CMS Collaborations in searches for the Higgs boson has been observed to decay into gamma gamma, ZZ* and WW*, but its spin an…
Expected Limits on R-symmetric Processes at Project X
Ricky Fok
We investigate processes in the Minimal R-symmetric Standrad Model (MRSSM) with the expected limits from Project X. It is found that conversion provides the tight…
Electroweak Baryogenesis in R-symmetric Supersymmetry
R. Fok, Graham D. Kribs, Adam Martin +1
We demonstrate that electroweak baryogenesis can occur in a supersymmetric model with an exact R-symmetry. The minimal R-symmetric supersymmetric model contains chiral superfields…
