WebMar 2, 2024 · A dynamic bayesian network consists of nodes, edges and conditional probability distributions for edges. Every edge in a DBN represent a time period and the network can include multiple time periods unlike markov models that only allow markov processes. DBN:s are common in robotics and data mining applications.
