Network Properties DBN Pane
===========================

Various Dynamic Bayesian Networks (DBN) parameters can be modified in the Network Properties DBN tab, shown in Figure 1. The parameters that can be modified are:

* The Number of Time Slices: Specifies the number of time slices that is generated when the model is compiled.
* Boyen-Koller approximation: Specifies the level of Boyen-Koller approximation to be used. The options are:
	* Disabled: No approximation is used.
	* Partial Boyen-Koller approximation (move time window and prediction)
* Full Boyen-Koller approximation (move time window, prediction and inside time window)

More details can be read about HUGIN's implementation of DBN models, time slices and Boyen-Koller approximation in HUGIN C API Help Document distributed along with the software.
