GAN is notorious for its instability when train the model. For the gen_gan_loss a value below 0. ' \B) F?KDW\B5 ' ' ' G y f z D~ x f x r y f c r/f P y r Figure 3. 通常GANではノイズが入力になりますが、ここではsynthetic imageが入力となります。また、損失関数では、self-regularization lossという損失も考慮します。これは元のsynthetic imageとgeneratorによって生成された画像の差分を小さくするためのものです。. 前回、自前のデータセットを使って画像分類(CNN)をしたので今回はGANにより画像を生成 してみようと思います。データセットに使うのは多部未華子ちゃんでいこうと思います データセット作成用画像 データセット作成 GANで. A GAN combines two neural networks, called a Discriminator (D) and a Generator (G). The first and the second rows are Male and Female, the third and the fourth rows are Male with Smile and. Note that the final version of the GAN can be trained for much longer than the other GANs, as it resets the training data once the GAN has already been fed each training image. Feature Loss는 Discriminator에서 최종 Real과 Fake로 판단하는 것도 좋지만, Mode Collapse등을 방지하기 위해서 중간 Feature가 실제 Image Domain 분포를 어느 정도 따라가야 한다는 ImprovedGAN 에서의 방법을 어느정도. One of the known reasons for this instability is the passage of uninformative gradients from the Discriminator to the Generator due to learning imbalance between them during training. They further suggested an auto-context model for image refinement. Image to Image Translation. This both speeds the training up and greatly stabilizes it, allowing us to produce images of unprecedented quality, e. We will use the images in the training dataset as the basis for training a Generative Adversarial Network. Random vectors are fed into the latent space to generate RGB images using the pre-trained generators. If you want to run it as script, please refer to the above link. Image Super-Resolution (ISR) The goal of this project is to upscale and improve the quality of low resolution images. Generative Adversarial Nets in TensorFlow.
