| Abstract(in English) | A Gaussian Process Regression (GPR) has ability to deal with a non-linear regression easily. However, the calculation cost increase as the sample size. Local GPR proposed in a recent year performs fast calculation for a GPR by dividing a dataset and constructing local models in each divided subspace. However, the integration procedure of local models is not based on a the original probabilistic model. In this paper, we propose a fast calculation method for a GPR by using a Locally-Sensitive Hashing and a Product of Experts model. We apply our proposed method to function approximation of an artificial data, and confirm the effect of reduction of the calculation cost. |
