Markov blanket

In machine learning, the Markov blanket for a node ${\displaystyle A}$ in a Bayesian network is the set of nodes ${\displaystyle \partial A}$ composed of ${\displaystyle A}$'s parents, its children, and its children's other parents. In a Markov random field, the Markov blanket of a node is its set of neighboring nodes. A Markov blanket may also be denoted by ${\displaystyle MB(A)}$.
