• all your node are chance values ... Genie is also used for other specifities that we will not use during this course
    So you need only the "yellow" chance nodes, and the arrows to define your graph
    then right click on the concerned node, node properties, in order to change its name and the names of the values), and "definition" to access to the interface to put the proba values
  •  when you define the values of your variable, you can't use values that begin with one number , so you can't define N1 = 0 or 1 for instance ... but you can define the values as n0 and n1 instead of 0 and 1
  • when you have a CPT (conditional probability table) with several parents, you can change the order of the parents with click and move the names of the variables in this interface
  • in the interface where you put the probabilities, you can select cells like in excel and copy/paste them in another probability table ...
  • CTRL A to select all your nodes, then right click - view as - bar chart ..
  • when your BN is defined, you can enter observations by double clicking on the observed values , and you can ask for all the probabilities of the other node by clicking into the update icon (the yellow thunder) or F5 - or choose to have this update done automatically with CTRL F5
