Recent years have witnessed the prevailing progress of Generative Adversarial Networks (GANs) in image-to-image translation. However, the success of these GAN models hinges on ponderous computational costs and labor-expensive training data. Current efficient GAN learning techniques often fall into two orthogonal aspects: i) model slimming via reduced calculation costs; ii)data/label-efficient learning with fewer training data/labels. To combine the best of both worlds, we propose a new learning paradigm, Unified GAN Compression (UGC), with a unified optimization objective to seamlessly prompt the synergy of model-efficient and label-efficient learning. UGC sets up semi-supervised-driven network architecture search and adaptive online semi-supervised distillation stages sequentially, which formulates a heterogeneous mutual learning scheme to obtain an architecture-flexible, label-efficient, and performance-excellent model.

近年来，生成对抗网络在图像到图像翻译中取得了显著进展，然而，这些GAN模型的成功依赖于繁重的计算成本和劳动密集型的训练数据。为了兼顾模型效率和标签效率的优点，我们提出了一种新的学习范式，统一生成对抗网络压缩，通过在网络架构搜索和自适应在线半监督蒸馏阶段之间建立半监督驱动的异构互学习方案，来获得一种灵活的、标签高效的和性能优越的模型。
