PARAMETER ESTIMATION METHOD, PARAMETER ESTIMATION DEVICE, AND CORRELATION METHOD

摘要

There is provided a parameter estimation method for estimating a parameter by estimating maximum posterior probability for input data. Calculation for the input data is expressed by an inner product for the input data and the inner product is replaced by a Kernel function. By using the calculation result of the Kernel function, a parameter is estimated. The method includes: a step (offline operation) for learning correlation between a plurality of learning input data in which the parameter to be estimated is known; and a step (online operation) for estimating the parameter for the estimation input data in which the parameter to be estimated is unknown, by using learned correlation.
