public class PerceptronModelReader
extends AbstractModelReader

The base class for readers of models. 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)

PerceptronModelReader

public PerceptronModelReader(File file)
                      throws IOException

Initializes a PerceptronModelReader via a File.

Parameter:

file - The File that references the model to be read.

Löst aus:

IOException - Thrown if IO errors occurred.

PerceptronModelReader

public PerceptronModelReader(DataReader dataReader)

Initializes a PerceptronModelReader via a DataReader.

Parameter:

Methodendetails

constructModel

public AbstractModel constructModel()
                             throws IOException

Constructs a model.

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.

constructModel in Klasse AbstractModelReader

Gibt zurück:

A PerceptronModel reconstructed from a model's (read) attributes.

Löst aus:

IOException - Thrown if IO errors occurred during (re-)construction.

checkModelType

public void checkModelType()
                    throws IOException

Reads the mode type from the underlying reader and informs if it not a Perceptron model.

Angegeben von:

checkModelType in Klasse AbstractModelReader

Löst aus:

IOException - Thrown if IO errors occurred.
