1. An information processing apparatus for generating image training data comprising:
a processor; and
a memory containing instructions that, when executed by the processor, cause the processor to function as:
a first obtaining unit configured to obtain one or more image feature vectors related to a first category, from a vector group including a plurality of image feature vectors, each associated with a category;
a second obtaining unit configured to obtain from the vector group one or more image feature vectors, at least one related to a second category different from the first category;
a calculation unit configured to calculate a transformation matrix for converting a projection source vector obtained based on an image feature vector obtained by the second obtaining unit into a projection destination vector obtained based on an image feature vector obtained by the first obtaining unit; and
a generation unit configured to generate image training data by generating a pseudo image feature vector related to a third category different from the first category and the second category by performing conversion processing on one or more image feature vectors included in the image feature vectors obtained by the second obtaining unit using the transformation matrix.
