One of the earliest attempts (1959) at machine learning, using an approach similar to a neural network. lowerorder demons learned to simplify features in the input data which were passed up to higher-order demons, etc. see also: machine learning, artificial neural networks.
Moral graph, английский
One of the steps in converting a directed acyclic graph (dag) into a junction tree is the conversion of the graph to a moral graph. a moral graph of a dag connects all immediate parents of a node and converts the resulting graph to an undirected graph. the cliques of this graph are used to construct the junction graph and junction tree. the figures below show a dag and its moral graph, with the added edges emphasized. see also: clique, junction graph. figure m.2 —
