SupervisedLearning
public SupervisedLearning()
setWatchManager
public void setWatchManager(WatchManager wm,
String name)
- Register all variables with this WatchManager.
This will be called after all parsing is done.
setWatchManager should be overridden and forced to
call the same method on all the other objects in the experiment.
- Overrides:
- setWatchManager in class ErrFun
BNF
public String BNF(int lang)
- Return the BNF description of how to parse the parameters of this object.
- Overrides:
- BNF in class ErrFun
unparse
public void unparse(Unparser u,
int lang)
- Output a description of this object that can be parsed with parse().
- Overrides:
- unparse in class ErrFun
- See Also:
- Parsable
parse
public Object parse(Parser p,
int lang) throws ParserException
- Parse the input file to get the parameters for this object.
- Throws: ParserException
- parser didn't find the required token
- Overrides:
- parse in class ErrFun
evaluate
public double evaluate(Random rnd,
boolean willFindDeriv,
boolean willFindHess,
boolean rememberNoise)
- return the scalar output for the current weight vector x
- Overrides:
- evaluate in class ErrFun
findGradient
public void findGradient()
- update the fGradient vector based on the dEdOutput
- Overrides:
- findGradient in class ErrFun
initialize
public void initialize(int level)
- Initialize, either partially or completely.
- Overrides:
- initialize in class ErrFun
- See Also:
- initialize
