StyleGAN: A Style-Based Generator Architecture for GANs We propose an alternative generator architecture for generative adversarial networks, borrowing from style transfer literature. The new architecture leads to an automatically learned, unsupervised separation of high-level attributes (e.g., pose and identity when trained on human faces) and stochastic variation in the generated images (e.g.,..

How to Choose the Batch Size? 일반적으로 아래 세 가지 batch size를 결정할 수 있으며, 배치 사이즈의 크기에 따라 딥러닝의 성능에 많은 영향을 미친다. Batch(deterministic) Gradient Descent Mini-Batch Gradient Descent Stochastic(Online) Gradient Descent Large Batch Small Batch Accurate estimate of the gradient (low variance) Noisy estimate of the gradient (high variance) High Computation cost per iteration Low computation cost per iteration Hi..
