Proper Straight-Through Estimator: Breaking symmetry promotes convergence to true minimum

no code implementations29 Sep 2021 Shinya Gongyo, Kohta Ishikawa

By considering the scale symmetry of the network and specific properties of the STEs, we find that STE with clipped Relu is superior to STEs with identity function and vanilla Relu.

$NΩ$ dibaryon from lattice QCD near the physical point

1 code implementation8 Oct 2018 Takumi Iritani, Sinya Aoki, Takumi Doi, Faisal Etminan, Shinya Gongyo, Tetsuo Hatsuda, Yoichi Ikeda, Takashi Inoue, Noriyoshi Ishii, Takaya Miyamoto, Kenji Sasaki

The nucleon($N$)-Omega($\Omega$) system in the S-wave and spin-2 channel ($^5$S$_2$) is studied from the (2+1)-flavor lattice QCD with nearly physical quark masses ($m_\pi \simeq 146$~MeV and $m_K \simeq 525$~MeV).

Systematics of the HAL QCD Potential at Low Energies in Lattice QCD

1 code implementation7 May 2018 Takumi Iritani, Sinya Aoki, Takumi Doi, Shinya Gongyo, Tetsuo Hatsuda, Yoichi Ikeda, Takashi Inoue, Noriyoshi Ishii, Hidekatsu Nemura, Kenji Sasaki

The $\Xi\Xi$ interaction in the $^1$S$_0$ channel is studied to examine the convergence of the derivative expansion of the non-local HAL QCD potential at the next-to-next-to-leading order (N$^2$LO).

Mirage in Temporal Correlation functions for Baryon-Baryon Interactions in Lattice QCD

1 code implementation21 Jul 2016 Takumi Iritani, Takumi Doi, Sinya Aoki, Shinya Gongyo, Tetsuo Hatsuda, Yoichi Ikeda, Takashi Inoue, Noriyoshi Ishii, Keiko Murano, Hidekatsu Nemura, Kenji Sasaki

Single state saturation of the temporal correlation function is a key condition to extract physical observables such as energies and matrix elements of hadrons from lattice QCD simulations.
