PROBLEM TO BE SOLVED: To provide an information processor for eliminating the need of information on a boundary between single characters as a teacher signal in machine learning in character recognition of a recognition object.SOLUTION: Reception means of the information processor receives semi-character pattern strings and correct answer text strings of a recognition object, creation means creates a first lattice including a sequence of character recognition results to the recognition object, and a second lattice including a sequence of the correct answer text strings to the recognition object by a combination of the semi-character pattern strings, and difference means respectively calculates expectation values of differential values of evaluation values of the sequences included in the first lattice and the second lattice created by the creation means, and calculates difference between the expectation value of the first lattice and the expectation value of the second lattice as a recognition parameter update value in machine learning.SELECTED DRAWING: Figure 6 |
