+----sim.funApp.SpiralFunction
- public class SpiralFunction
- extends FunApp
-
SpiralFunction()
-
-
BNF(int)
-
-
clone()
- Make an exact duplicate of this class.
-
cloneVars(FunApp)
- After making a copy of self during a clone(), call cloneVars() to
copy variables into the copy, then return super.cloneVars(copy).
-
evaluate()
- calculate the output for the given input
-
findGradients()
- Calculate the output and gradient for a given input.
-
findHessian()
- Calculate the output, gradient, and Hessian for a given input.
-
nWeights(int, int)
- Return # elements (weights) in the lookup table.
-
parse(Parser, int)
- Parse the input file to get the parameters for this object.
-
setIO(MatrixD, MatrixD, MatrixD, MatrixD, MatrixD, MatrixD, MatrixD, MatrixD, MatrixD)
- Define the MatrixD objects that will be used by evaluate()
and findGradients().
-
unparse(Unparser, int)
- Output a description of this object that can be parsed with parse().
SpiralFunction
public SpiralFunction()
setIO
public void setIO(MatrixD inVect,
MatrixD outVect,
MatrixD weights,
MatrixD dEdIn,
MatrixD dEdOut,
MatrixD dEdWeights,
MatrixD dEdIndIn,
MatrixD dEdOutdOut,
MatrixD dEdWeightsdWeights) throws MatrixException
- Define the MatrixD objects that will be used by evaluate()
and findGradients(). All 6 should be column vectors (n by 1 matrices).
All the MatrixD objects are copied, but the pointers still point
to the same data arrays.
- Throws: MatrixException
- if vector shapes don't match
- Overrides:
- setIO in class FunApp
evaluate
public void evaluate()
- calculate the output for the given input
- Overrides:
- evaluate in class FunApp
findGradients
public void findGradients()
- Calculate the output and gradient for a given input.
This does everything evaluate() does, plus it calculates
the gradient of the error with respect to the inputs and
weights, dEdx and dEdw,
User must set dEdOut before calling.
- Overrides:
- findGradients in class FunApp
findHessian
public void findHessian()
- Calculate the output, gradient, and Hessian for a given input.
This does everything evaluate() and findGradients() do, plus
it calculates the Hessian of the error with resepect to the
the weights and inputs, dEdxdx, dEdwdx, and dEdwdw.
- Overrides:
- findHessian in class FunApp
nWeights
public int nWeights(int nIn,
int nOut)
- Return # elements (weights) in the lookup table.
- Overrides:
- nWeights in class FunApp
BNF
public String BNF(int lang)
- Overrides:
- BNF in class FunApp
unparse
public void unparse(Unparser u,
int lang)
- Output a description of this object that can be parsed with parse().
- Overrides:
- unparse in class FunApp
- 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 FunApp
clone
public Object clone()
- Make an exact duplicate of this class. For objects it contains, it
only duplicates the pointers, not the objects they point to. For a
new FunApp called MyFunApp, the code in this method should be the
single line: return cloneVars(new MyFunApp());
- Overrides:
- clone in class FunApp
cloneVars
public Object cloneVars(FunApp copy)
- After making a copy of self during a clone(), call cloneVars() to
copy variables into the copy, then return super.cloneVars(copy).
The variables copied are just those set in parse() and
setWatchManager(). The caller will be required to call
setIO to set up the rest of the variables.
- Overrides:
- cloneVars in class FunApp
