The direct … See more Let $${\displaystyle z_{0}}$$ be a (possibly multivariate) random variable with distribution $${\displaystyle p_{0}(z_{0})}$$. For $${\displaystyle i=1,...,K}$$, let The log likelihood of See more As is generally done when training a deep learning model, the goal with normalizing flows is to minimize the Kullback–Leibler divergence between the model's likelihood and the target distribution to be estimated. Denoting $${\displaystyle p_{\theta }}$$ the model's likelihood and See more Flow-based generative models have been applied on a variety of modeling tasks, including: • Audio generation • Image generation • Molecular graph generation See more Planar Flow The earliest example. Fix some activation function $${\displaystyle h}$$, and let $${\displaystyle \theta =(u,w,b)}$$ with th appropriate … See more Despite normalizing flows success in estimating high-dimensional densities, some downsides still exist in their designs. First of all, their latent space where input data is projected onto is not a lower-dimensional space and therefore, flow-based models do … See more • Flow-based Deep Generative Models • Normalizing flow models See more

WebOct 30, 2024 · In this paper, we propose GF-VAE, a flow-based variational autoencoder (VAE) model for molecular graph generation. Specifically, the model equips VAE a lightweight flow model as its decoder, in which, the encoder aims to accelerate the training process of the decoder, while the decoder in turns to optimize the performance of the …WebApr 4, 2024 · 本来想在上一篇博客Blow后面写的，因为他属于是flow-based model，但是我不知道在哪里修改上一篇博客····· 目前主流的生成模型有三大类（我只用过后两类方法···） 首先是component by component 生成是序列的，不确定生成的顺序以及比较好使，VAE的训练目标只是优化下界，GAN的训练又很不稳定。truvarin website
