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. |
