Information processing apparatus, information processing method, non-transitory computer-readable storage medium

An information processing method performed by an information processing apparatus, the method comprising:

• converting an element array, in each region set so as to partially overlap at least one set of adjacent regions in input data, into a lower dimension element array of which dimension is lower than that of the element array;
• generating a connected element by connecting some or all of the lower dimension element arrays converted in the converting so that an overlapping portion in each of the lower dimension element arrays will be shared;
• and
• obtaining a feature amount of the input data based on convolution of the connected elements and a weight coefficient.

A non-transitory computer-readable storage medium storing a computer program for causing a computer to function as

• a conversion unit configured to convert an element array, in each region set so as to partially overlap at least one set of adjacent regions in input data, into a lower dimension element array of which dimension is lower than that of the element array of a lower dimension;
• a generation unit configured to generate a connected element by connecting some or all of the lower dimension element arrays converted by the conversion unit so that an overlapping portion in each of the lower dimension element arrays will be shared;
• and
• a calculation unit configured to obtain a feature amount of the input data based on convolution of the connected elements and a weight coefficient.
