Associate Dictionary — Node

  • Use Node Renaming to rename each node with a new name.
  • Use Comments to associate a Comment with each node that is in the file.
  • Use Classes to organize nodes in subsets called Classes. A node can belong to several classes at the same time. These classes allow generalizing some node properties to the nodes belonging to the same classes. They also allow creating constraints on arc creation during learning.
  • Use Colors to associate colors with the nodes or Classes that are in the file. The colors are specified as 9-bit RGB with 8 bits per channel in hexadecimal format (web format). For example, the color red corresponds to an RGB value of 255, 0, 0 or hex #FF0000.
  • Use Images to associate images with the nodes or Classes that are in the file. The images are represented by their path relative to the directory where the dictionary is.
  • Use Costs to associate a Cost with each node. A node without a Cost value is also considered not observable.
  • Use Temporal Indices to associate Temporal Indices with the nodes that are in the file. The temporal indices are used by BayesiaLab’s learning algorithms to account for constraints on possible probabilistic relationships, such as not adding any arcs between future nodes and past nodes. The rule used to add an arc from node N1 to node N2 is:
    • If the temporal index of N1 is positive or null, then the arc from N1 to N2 is only possible if the temporal index of N2 is greater than or equal to the index of N1.
  • Use Local Structural Coefficients to set the Local Structural Coefficient of each specified node or each node of each specified class.
  • Use State Virtual Numbers to set State Virtual Numbers for each specified node or all nodes in a specified class.
  • Use Locations to set the position of a node on the Graph Panel.
