Energy-based Generative Adversarial Network 结合 DANN 的模型;
2 方法
整体框架:
$\\textDANN$ 训练目标:
$\\beginarrayl\\undersetG_f, G_y\\textmin \\quad \\mathcalL_y\\left(\\mathbfX_s, Y_s\\right)-\\gamma \\mathcalL_f\\left(\\mathbfX_s, \\mathbfX_t\\right) \\\\\\undersetG_d\\textmin \\quad \\mathcalL_d\\left(\\mathbfX_s, \\mathbfX_t\\right)\\endarray$
本文训练目标:
$\\beginarrayl\\undersetG_f, G_y\\textmin \\quad \\mathcalL_C E\\left(\\mathbfX_s, Y_s\\right)+\\gamma \\mathcalL_A E\\left(\\mathbfX_\\mathbft\\right), \\\\\\undersetG_a\\textmin\\quad \\mathcalL_A E\\left(\\mathbfX_\\mathbfs\\right)+\\max \\left(0, m-\\mathcalL_A E\\left(\\mathbfX_\\mathbft\\right)\\right)\\endarray$
$\\mathcalL_A E\\left(\\mathbfx_i\\right)=\\left\\|G_a\\left(G_f\\left(\\mathbfx ; \\theta_f\\right) ; \\theta_a\\right)-\\mathbfx_i\\right\\|_2^2$
