Information conversion device, computer-readable recording medium, and information conversion method

摘要

An information conversion device includes a memory and a processor coupled to the memory. The processor executes a process including generating a conversion rule for converting a feature quantity vector into a binary string that is longer than a predetermined bit length. The process includes converting each of the feature quantity vectors into a binary string by using the conversion rule generated at the generating. The process includes calculating importance levels of the respective bits in the binary strings based on the distance-based relations among the feature quantity vectors. The process includes correcting the conversion rule into one that converts each of the feature quantity vectors into a binary string having the predetermined bit length based on the calculated importance levels. The process includes changing the feature quantity vectors into a binary string having the predetermined bit length by using the conversion rule corrected at the correcting.

1. An information conversion rule generating apparatus comprising:
a memory; and a processor coupled to the memory, wherein the processor executes a process comprising: first generating a first conversion rule for converting a feature quantity vector into a binary string with a first bit length that is longer than a predetermined bit length; converting a first plurality of feature quantity vectors into a first plurality of binary strings by using the first conversion rule, first relationship information that include relationships of the first plurality of feature quantity vectors being stored in the memory; calculating distance fidelity values for each bit of a binary string converted by the first conversion rule, based on the first relationship information and bit values of the first plurality of binary strings; and second generating a conversion rule for converting a feature quantity vector into a binary string with the predetermined bit length, based on the first conversion rule and the calculated distance fidelity values.
