Recent advances in generative models trained on large-scale datasets have made it possible to synthesize high-quality samples across various domains. Moreover the emergence of strong inversion networks enables not only a reconstruction of real-world images but also the modification of attributes through various editing methods. However in certain domains related to privacy issues e.g. human faces advanced generative models along with strong inversion methods can lead to potential misuses. In this paper we propose an essential yet under-explored task called generative identity unlearning which steers the model not to generate an image of a specific identity. In the generative identity unlearning we target the following objectives: (i) preventing the generation of images with a certain identity and (ii) preserving the overall quality of the generative model. To satisfy these goals we propose a novel framework Generative Unlearning for Any Identity (GUIDE) which prevents the reconstruction of a specific identity by unlearning the generator with only a single image. GUIDE consists of two parts: (i) finding a target point for optimization that un-identifies the source latent code and (ii) novel loss functions that facilitate the unlearning procedure while less affecting the learned distribution. Our extensive experiments demonstrate that our proposed method achieves state-of-the-art performance in the generative machine unlearning task.
