We propose a method for forecasting intermittent demand with generalized state-space model using time series data. Specifically, we employ mixture of zero and Poisson distributions. To show the superiority of our method to the Croston, Log Croston an

A quantum mechanical model is given which is equivalent to the stochastic dephasing subject to the two-state jump Markovian process. The stochastic variable corresponds to a Hermitian operator of a spin-1/2 system which is embedded in a thermal reser

The eigenfunction expansion by Gegenbauer polynomials for the diffusion on a hypersphere is transformed into the diffusion for the Wright–Fisher model with a particular mutation rate. We use the Ito calculus considering stochastic differential equa

In this paper, the database that controls the indoor spatial information for robots and users is referred to as the spatial master database. We designed a data model and a map output model of the spatial master database. Based on the model, a spatial

A "mixed autoregressive hidden Markov model" (MAR-HMM) is proposed for modeling people's movements. MAR-HMM is equivalent to a special case of an autoregressive hidden Markov model (AR-HMM), which takes into account changes of people's internal prope

A method for predicting pedestrian movement on the basis of a mixed Markov-chain model (MMM) is proposed. MMM takes into account a pedestrian's personality as an unobservable parameter. It also takes into account the effects of the pedestrian's previ

In order to clarify the effect of selfing on genetic variation in geographically structured populations, Wright's island model is generalized to include; the effects of extinction, mutation, selfing, and migration of pollen and seed. The equilibrium

In this paper, we discuss statistical analysis of human trajectories measured by GPS-like positioning devices. Our goal is to develop a system of trajectory analysis that distributes information optimized for each user. For such a system, we need a m
