Title:

EMOTION ESTIMATION DEVICE, METHOD, AND COMPUTER PROGRAM

Document Type and Number:

Japanese Patent JP2022072619

Kind Code:

A

Abstract:

To provide an emotion estimation device capable of enhancing the accuracy of emotion estimation by combining outputs of a single-modality model.SOLUTION: An emotion estimation device includes: a multi-head GAT 66 that updates respective features of a plurality of kinds of modalities by relevance present between features obtained for the plurality of kinds of modalities; and a fully connected layer 68 that estimates an emotion of a person by using the updated features of the plurality of kinds of modalities. The multi-head GAT 66 includes update units 100, 102, and 104 that calculate correlations present between features obtained for the plurality of kinds of modalities as attentions between nodes in a graph neural network which has features as nodes and has edges connecting the respective nodes, and updates a feature of a node in question by using an attention from each of adjacent nodes which are adjacent to the node among the attentions.SELECTED DRAWING: Figure 2
