Description

This paper proposes a clustering model using deep metric learning for a content-based retrieval system focusing on the illustration art style. Unlike the conventional methods, which train models using heuristic features or probability distributions of specific labels, the proposed method jointly optimizes the latent space of the Variational Autoencoder with Triplet loss. Objective evaluation with unseen data revealed that the proposed method achieved an NMI score of 51.71%, 10.61% higher than the conventional method. Furthermore, when used in a similarity retrieval system, the proposed method was found to recommend images with perceptual similarities in the query about the art style.
