Neural network representation of quantum systems

no code implementations18 Mar 2024 Koji Hashimoto, Yuji Hirono, Jun Maeda, Jojiro Totsuka-Yoshinaka

It has been proposed that random wide neural networks near Gaussian process are quantum field theories around Gaussian fixed points.

Understanding Diffusion Models by Feynman's Path Integral

no code implementations17 Mar 2024 Yuji Hirono, Akinori Tanaka, Kenji Fukushima

Score-based diffusion models have proven effective in image generation and have gained widespread usage; however, the underlying factors contributing to the performance disparity between stochastic and deterministic (i. e., the probability flow ODEs) sampling schemes remain unclear.

Unification of Symmetries Inside Neural Networks: Transformer, Feedforward and Neural ODE

no code implementations4 Feb 2024 Koji Hashimoto, Yuji Hirono, Akiyoshi Sannai

Understanding the inner workings of neural networks, including transformers, remains one of the most challenging puzzles in machine learning.

Complete characterization of robust perfect adaptation in biochemical reaction networks

1 code implementation14 Jul 2023 Yuji Hirono, Ankit Gupta, Mustafa Khammash

The present results indicate that an RPA property is essentially equivalent to the existence of a "topological invariant", which is an instance of what we call the "Robust Adaptation is Topological"(RAT) principle.

Robust Perfect Adaptation of Reaction Fluxes Ensured by Network Topology

no code implementations2 Feb 2023 Yuji Hirono, Hyukpyo Hong, Jae Kyoung Kim

Maintaining stability in an uncertain environment is essential for proper functioning of living systems.

Structural reduction of chemical reaction networks based on topology

no code implementations15 Feb 2021 Yuji Hirono, Takashi Okada, Hiroyasu Miyazaki, Yoshimasa Hidaka

A subnetwork can be eliminated systematically to give a reduced system with fewer degrees of freedom.
