Quantum natural gradient without monotonicity

no code implementations24 Jan 2024 Toi Sasaki, Hideyuki Miyahara

Initially, we demonstrate that monotonicity is a crucial condition for conventional QNG to be optimal.

Information geometric bound on general chemical reaction networks

no code implementations19 Sep 2023 Tsuyoshi Mizohata, Tetsuya J. Kobayashi, Louis-S. Bouchard, Hideyuki Miyahara

We investigate the dynamics of chemical reaction networks (CRNs) with the goal of deriving an upper bound on their reaction rates.

Deterministic Quantum Annealing Expectation-Maximization Algorithm

no code implementations19 Apr 2017 Hideyuki Miyahara, Koji Tsumura, Yuki Sughiyama

Maximum likelihood estimation (MLE) is one of the most important methods in machine learning, and the expectation-maximization (EM) algorithm is often used to obtain maximum likelihood estimates.

Relaxation of the EM Algorithm via Quantum Annealing for Gaussian Mixture Models

no code implementations12 Jan 2017 Hideyuki Miyahara, Koji Tsumura, Yuki Sughiyama

We propose a modified expectation-maximization algorithm by introducing the concept of quantum annealing, which we call the deterministic quantum annealing expectation-maximization (DQAEM) algorithm.

Relaxation of the EM Algorithm via Quantum Annealing

no code implementations5 Jun 2016 Hideyuki Miyahara, Koji Tsumura

The EM algorithm is a novel numerical method to obtain maximum likelihood estimates and is often used for practical calculations.
