Temporal Portability of Numeric User Metadata on Twitter
Chako Takahashi, Mitsuo Yoshida, Muneki Yasuda
Numeric user metadata in social media are often reused over time. However, their reusability may depend on what an analysis needs to preserve. We introduce temporal portability as…
Dataset-Free Weight-Initialization on Restricted Boltzmann Machine
Muneki Yasuda, Ryosuke Maeno, Chako Takahashi
In feed-forward neural networks, dataset-free weight-initialization methods such as LeCun, Xavier (or Glorot), and He initializations have been developed. These methods randomly de…
Free Energy Evaluation Using Marginalized Annealed Importance Sampling
Muneki Yasuda, Chako Takahashi
The evaluation of the free energy of a stochastic model is considered a significant issue in various fields of physics and machine learning. However, the exact free energy evaluati…
Adaptive Thouless--Anderson--Palmer equation for higher-order Markov random fields
Chako Takahashi, Muneki Yasuda, Kazuyuki Tanaka
The adaptive Thouless--Anderson--Palmer (TAP) mean-field approximation is one of the advanced mean-field approaches, and it is known as a powerful accurate method for Markov random…
Statistical-mechanical analysis of compressed sensing for Hamiltonian estimation of Ising spin glass
Chako Takahashi, Masayuki Ohzeki, Shuntaro Okada +3
Several powerful machines, such as the D-Wave 2000Q, dedicated to solving combinatorial optimization problems through the Ising-model formulation have been developed. To input prob…
Perturbative Interpretation of Adaptive Thouless-Anderson-Palmer Free Energy
Muneki Yasuda, Chako Takahashi, Kazuyuki Tanaka
In conventional well-known derivation methods for the adaptive Thouless-Anderson-Palmer (TAP) free energy, special assumptions that are difficult to mathematically justify except i…
Mean-Field Inference in Gaussian Restricted Boltzmann Machine
Chako Takahashi, Muneki Yasuda
A Gaussian restricted Boltzmann machine (GRBM) is a Boltzmann machine defined on a bipartite graph and is an extension of usual restricted Boltzmann machines. A GRBM consists of tw…
