constructModel
public AbstractModel constructModel() throws java.io.IOException
Retrieve a model from disk. It assumes that models are saved in the following sequence:
Perceptron (model type identifier)
1. # of parameters (int)
2. # of outcomes (int)
* list of outcome names (String)
3. # of different types of outcome patterns (int)
* list of (int int[])
[# of predicates for which outcome pattern is true] [outcome pattern]
4. # of predicates (int)
* list of predicate names (String)If you are creating a reader for a format which won't work with this (perhaps a database or xml file), override this method and ignore the other methods provided in this abstract class.
