However, the model parameters such as learning rate are always fixed, which have an adverse effect on the convergence speed and accuracy of fault classification. In the current severe epidemic, our model can detect COVID-19 positive cases quickly and efficiently. endobj Sparse autoencoder 1 Introduction Supervised learning is one of the most powerful tools of AI, and has led to automatic zip code recognition, speech recognition, self-driving cars, and a continually improving understanding of the human genome. 0000034455 00000 n 1 0 obj 21 0 obj The network, optimized by layer-wise training, is constructed by stacking layers of denoising auto-encoders in a convolutional way. In this paper, we propose the "adversarial autoencoder" (AAE), which is a probabilistic autoencoder that uses the recently proposed generative adversarial networks (GAN) to perform variational inference by matching the aggregated posterior of the hidden code vector of the autoencoder with an arbitrary prior distribution. 0000008937 00000 n Recently, stacked autoencoder framework have shown promising results in predicting popularity of social media posts, which is helpful for online advertisement strategies. endobj Activation Functions): If no match, add something for now then you can add a new category afterwards.
