Prediction¶
In a DBN we can compute beliefs for nodes in time slices that lie beyond the time window. This operation is called prediction.
Note
only DBNs entirely consisting of discrete nodes supports prediction.
To perform prediction, click the prediction button and summon the prediction wizard.
Prediction Wizard¶
The belief prediction wizard has two tabs for configuring the computations. First configure the number of time slices beyond the current time window to predict.

Next pick the nodes we wish to predict.

Finally when done configuring click the OK button to compute predictions. When computation is done a data frame appears with the predicted beliefs.

Figure 3: A data frame displaying the predicted beliefs. Each row represents a time slice. The first 0 to (n - number of slices to predict) rows are the time slices from the current window and the remaining rows are the predicted time slices.¶
