Title:
MULTI-DIMENSIONAL DATA VISUALIZATION DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/071143
Kind Code:
A1
Abstract:
An embodiment of the present invention is provided with a projective transformation model which has a plurality of nodes that retain reference vectors having dimensions corresponding to multi-dimensional data, and which also has a projection table. The projection table represents the correspondence between the numbers of the nodes and the coordinates in a two-dimensional space to which the reference vector retained by each node is projected. Initially in a learning phase, positive-example and negative-example multi-dimensional input data are acquired, amplitude feature quantities of the respective multi-dimensional input data are calculated, and data of the respective amplitude feature quantities are learned for each sample as the reference vectors of the plurality of nodes. Next, a calculation is made of the Euclidean distance between coordinates when a node learned using the positive-example amplitude feature quantity data and a node learned using the negative-example amplitude feature quantity data have been projected to the two-dimensional space in accordance with the projection table, and coordinates in the projection table are updated such that the calculated Euclidean distance is at least equal to a threshold value.
