A Quantum Extension of Variational Bayes Inference

no code implementations13 Dec 2017 Hideyuki Miyahara, Yuki Sughiyama

Variational Bayes (VB) inference is one of the most important algorithms in machine learning and widely used in engineering and industry.

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.
