There are increasingly apparent limitations of Bayesian Networks. For real-world applications, they are not expressive enough. Bayesian networks have the problem that involves the same fixed number of attributes.
There are a number of different online sources of information regarding Bayesian networks. These include Wikipedia, Bayes Nets and Bayes Server amongst others.
International Society for Bayesian Analysis was created in 1992.

Pignistic and Bayesian ?
One prerequisite for Bayesian statistics is that you need to know or have prior knowledge of the opposite of the probability you are trying to create.
Bayesian refers to a branch of statistics in which the true nature of a non-deterministic event are not known but are expressed as probabilities. These are improved as more evidence is gathered.
VBNN stands for Variational Bayesian Neural Networks. This approach combines variational inference with neural networks, allowing for the estimation of uncertainty in the model's predictions. By approximating the posterior distribution of the network's weights, VBNNs can provide insights into model confidence and robustness, making them useful in scenarios where uncertainty quantification is essential.
Bayesian spam filters are used to calculate the probability of a message being spam, based on the contents of the message. Bayesian spam filters learn from spam and from good mail, which later results in hardly any spam coming through to a mailbox.
Bayesian analysis is based on the principle that the true state of systems is unknown and is expressed in terms of its probabilities. These probabilities are improved as evidence is compiled.
A Bayesian network is a directed acyclic graph whose vertices represent random variables and whose directed edges represent conditional dependencies.

Two examples of graphical models are Bayesian networks, which represent probabilistic relationships among variables, and Markov random fields, which model dependencies between variables in spatially connected domains.
