We applied the Markov random field model, which is a kind of a Bayesian probabilistic
method, to the spatial inversion of the porosity and pore shape in rocks from an observed …

We apply the Markov-random-field model to linear seismic tomography and propose a
method to estimate the hyperparameters for the smoothness and the magnitude of the noise …

The chemical zoning profile in metamorphic minerals is often used to deduce the pressure–
temperature (P–T) history of rock. However, it remains difficult to restore detailed paths from …

We propose a method for optimizing bin widths for multidimensional histograms. The
optimization criterion is based on a cost function representing the tradeoff between the …

Alpha rhythm is a major component of spontaneous electroencephalographic (EEG) data.
We develop a novel method that can be used to estimate the instantaneous phases and …

抄録 Analytical instruments which has been gradually improved are widely used to get
various property of analyte. Those techniques give analysts much bigger data that makes …

Bayesian methods are often applied for estimating the event rate from a series of event
occurrences. However, the Bayesian posterior distribution requires the computation of the …

In recent years, a large amount of four-dimensional event data have been obtainable in
neutron inelastic scattering experiments conducted by chopper spectrometers at Japan …
