Stochastic Lifted Bayesian Networks


Stochastic Lifted Bayesian Networks – The algorithm for constructing a probabilistic model for a target (or for the entire dataset) is shown to operate optimally. In the case of the sample drawn from the target set the cost function is derived from the probability of the target to be observed. The key to the method is the use of the assumption of mutual information between the data and the target to define a policy and its prediction using random variables. When the covariance matrix of the target set is unknown the procedure to approximate the model is described. The algorithm has been used to learn the model parameters and to learn the posterior distribution in such a manner that the model’s predictions can be made, which enables the learner to make a decision if necessary for the learner to do so. The proposed method can be applied to many situations, including medical imaging, and it can easily be extended to situations where data are available.

We have proposed a new framework for the topic modeling problem, a generalization of the problem of solving a Markov decision process (MDP) with a nonconvex problem, where a priori knowledge is sufficient to decide on a set of subspaces to be solved. This framework is able to handle both the large-scale and high-dimensional datasets, while providing an efficient and reliable learning of the model structure, in practice. The approach for solving a high-dimensional MDP is based on minimizing a posterior in a generative model while computing the posterior function. We propose a method based on stochastic gradient descent, which allows us to sample efficiently from a large training set. We evaluate our method from a novel data set, Kalevala, where we have solved it using a large collection of high-dimensional graphs. In all cases, our solution reached a mean error rate of $3.37$ and a median error of $4.13$ on a number of datasets.
