Bayesian inference of causal gene networks
... of using these functions is that they are defined as a linear combination of basis functions, thus the model parameters are the coefficients of a linear combination, meaning that the parameters can be sampled from using ...

Bayesian Inference of gene-miRNA regulatory networks
... The second issue we need to work on is the log-probability level. We want to make sure the chain does not reach a point where the model explodes, all the potential interactions becoming functional. That is the reason why ...

The parameterized complexity of approximate inference in Bayesian networks
... exact inference for every D e > 1 is #P-hard (by reducing from #3S AT ); this implies that we cannot have an absolute approximation for arbitrary as we could then round the approximate result in order to recover ...

Learning Bayesian networks with low inference complexity
... The reason for using approximate inference is that the MDL score, that is used in combination with 2iCHC, does not penalize the infer- ence complexity of the models, so the computation[r] ...
