Overdispersed Black-Box Variational Inference I General variational inference for any probabilistic model WebMar 3, 2016 · We introduce overdispersed black-box variational inference, a method to reduce the variance of the Monte Carlo estimator of the gradient in black-box variational …
Overdispersed Black-Box Variational Inference
Webalgorithm can be interpreted as implicitly doing black-box variational inference (BBVI) with a nonparametric normal-izing flow. One can view this derivation as a translation of the … WebMay 19, 2024 · The ability to fit complex generative probabilistic models to data is a key challenge in AI. Currently, variational methods are popular, but remain difficult to train due to high variance of the sampling methods employed. We introduce the overdispersed variational autoencoder and overdispersed importance weighted autoencoder, which … fanta zevent 2021

Webvariance. However, theirs is not a black-box method. Both the objective function and control variates they propose require model-speci c derivations. 2 Black Box Variational Inference Variational inference transforms the problem of approx-imating a conditional distribution into an optimization problem (Jordan et al., 1999; Bishop, 2006; Wainwright WebApr 9, 2024 · 变分推断。在贝叶斯方法中,针对含有隐变量的学习和推理,通常有两类方式,其一是马尔可夫链蒙特卡罗法 (mcmc),其通过采样来近似估计后验概率分布;其二是变分推断,通过解析的方法近似计算后验概率分布。 WebApr 11, 2024 · Automatic differentiation variational inference (ADVI) offers fast and easy-to-use posterior approximation in multiple modern probabilistic programming languages. However, its stochastic optimizer lacks clear convergence criteria and requires tuning parameters. Moreover, ADVI inherits the poor posterior uncertainty estimates of mean … fanta vermelha
