WebFeb 14, 2024 · Normalizing flow-based deep generative models learn a transformation between a simple base distribution and a target distribution. In this post, we show how to use FastFlows to model a dataset of small molecules and generate new molecules. FastFlows allows us to generate thousands of valid molecules in seconds and shows the … WebWe propose a new Poisson flow generative model (PFGM) that maps a uniform distribution on a high-dimensional hemisphere into any data distribution. ...

WebApr 8, 2024 · Deep generative models such as variational autoencoders (VAEs) [3, 4], generative adversarial networks (GANs) [5, 6], recurrent neural networks (RNNs) [7,8,9,10], flow-based models [11, 12], transformer-based models [13, 14], diffusion models [15, 16] and variants or combinations of these models [17,18,19,20,21] have quickly advanced … WebFlow-based generative models: A flow-based generative model is constructed by a sequence of invertible transformations. Unlike other two, the model explicitly learns the data distribution p ( x ) and therefore the loss function is simply the negative log-likelihood. maughan reynolds gateshead

Flow-based generative models have been applied on a variety of modeling tasks, including: Audio generation Image generation Molecular graph generation Point-cloud modeling Video generation Lossy image compression See more A flow-based generative model is a generative model used in machine learning that explicitly models a probability distribution by leveraging normalizing flow, which is a statistical method using the change-of-variable law … 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 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 Let $${\displaystyle z_{0}}$$ be a (possibly multivariate) random variable with distribution $${\displaystyle p_{0}(z_{0})}$$.
