To provide a device which supports novel design.SOLUTION: A design support device 100 generates an output image IMG_OUT of a second domain, to which a design object product belongs, when an input image IMG_IN of a first domain, to which a motif of designing belongs, is given. An arithmetic processing unit 110 mounts a learned model 121 of CycleGAN (Generative Adversarial Networks) which has learned to be able to generate the output image IMG_OUT corresponding to the input image IMG_IN. A loss function used in a machine learning step includes a term of consistency loss of the first domain weighted by a first coefficient λ1 and a term of consistency loss of the second domain weighted by a second coefficient λ2 different from the first coefficient λ1.SELECTED DRAWING: Figure 1
【課題】新規性のあるデザインを支援する装置を提供する。【解決手段】デザイン支援装置100は、設計のモチーフが属する第1ドメインの入力画像IMG_INを与えると、設計対象の製品が属する第2ドメインの出力画像IMG_OUTを生成する。演算処理装置110には、入力画像IMG_INに対応する出力画像IMG_OUTを生成可能に学習された、CycleGAN(GenerativeAdversarialNetworks)の学習済みモデル121が実装される。機械学習の工程において使用される損失関数は、第1係数λ1で重み付けされた第1ドメインの一貫性損失の項と、第1係数λ1と異なる第2係数λ2で重み付けされた第2ドメインの一貫性損失の項を含む。【選択図】図1
