Deterministic Quantum Annealing Expectation-Maximization Algorithm

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 likeli…

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

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…

Relaxation of the EM Algorithm via Quantum Annealing

Hideyuki Miyahara, Koji Tsumura

The EM algorithm is a novel numerical method to obtain maximum likelihood estimates and is often used for practical calculations. However, many of maximum likelihood estimation pro…
