Information processing device, personal identification device, information processing method, and storage medium

An information processing method comprising:

• (a) acquiring one element of sequential data;
• (b) acquiring past data, the past data being related to an element acquired in a past;
• (c) calculating an indicator indicating which of a plurality of classes is appropriate for the one element to belong to, in consideration of the one element and the past data;
• (d) acquiring an integrated indicator calculated in the past;
• (e) integrating the indicator calculated for the one element and the integrated indicator calculated in the past to calculate an updated integrated indicator;
• (f) determining whether or not the sequential data can be classified into one of the plurality of classes based on the updated integrated indicator;
• (g) repeating processes (a) to (f) if it is determined that the sequential data cannot be classified into one of the plurality of classes;
• and
• (h) classifying the sequential data into one of the plurality of classes if it is determined that the sequential data can be classified into one of the plurality of classes.

A non-transitory storage medium storing a program that causes a computer to perform an information processing method, comprising:

• (a) acquiring one element of sequential data;
• (b) acquiring past data, the past data being related to an element acquired in a past;
• (c) calculating an indicator indicating which of a plurality of classes is appropriate for the one element to belong to, in consideration of the one element and the past data;
• (d) acquiring an integrated indicator calculated in the past;
• (e) integrating the indicator calculated for the one element and the integrated indicator calculated in the past to calculate an updated integrated indicator;
• (f) determining whether or not the sequential data can be classified into one of the plurality of classes based on the updated integrated indicator;
• (g) repeating processes (a) to (f) if it is determined that the sequential data cannot be classified into one of the plurality of classes;
• and
• (h) classifying the sequential data into one of the plurality of classes if it is determined that the sequential data can be classified into one of the plurality of classes.
