Variational Inference (VI) MCMC 的计算复杂度比较高,序列收敛的时间更长,但是 MCMC 本质上是一个渐进无偏估计 (asymptotically unbiased estimation),所以相对于 VI,MCMC 的精度更高。VI 使用一个简单分布拟合复杂的分布,必然会引入 bias,但是 VI 的效率很高,适合用在大规模计算中(比如 VAE,Variational AutoEncoder...

4.1 Overview of Bayesian inference As it provides a flexible and practical approximating system, Bayesian inference and the associated algorithms have seen tremendous popularity in recent decades in longitudinal data analysis. With their widespread applications, Bayes formulations will be frequently used in...

Bayesian inference Gibbs sampling breast cancer Author Information Show + 1. Introduction The era of “big data” has arrived to the field of computational biology [1]. Biological systems are so complex that in many situations, it is not feasible to directly measure the target signals. Actually...
Bayesian inferenceA finite element (FE) model is developed for a curved cable-stayed footbridge located in Terni (Umbria Region, Central Italy) which accounts for uncertainties in geometry, material properties, and boundary conditions as well as limited knowledge on the behavior of connections and ...

Overall, the neural implementation of inference and choice in our POMDP framework is both simple and plausible. Results We developed and tested our model using behavioral data from monkeys performing a direction discrimination task with post-decision wagering (Fig. 1a)2. On each trial, monkeys ...
These two hypotheses cast synaptic plasticity as a problem of Bayesian inference, and thus provide a normative view of learning. They generalize known learning rules, offer an explanation for the large variability in the size of postsynaptic potentials and make falsifiable experimental predictions. This...
Bayesian analysis, a method of statistical inference (named for English mathematician Thomas Bayes) that allows one to combine prior information about a population parameter with evidence from information contained in a sample to guide the statistical in
