BooleanSpace

java.lang.Object
- org.deeplearning4j.arbiter.optimize.parameter.BooleanSpace

All Implemented Interfaces:

ParameterSpace<java.lang.Boolean>
```
public class BooleanSpace
extends java.lang.Object
implements ParameterSpace<java.lang.Boolean>
```
BooleanParameterSpace is a ParameterSpace<Boolean>; Defines {True, False} as a parameter space If argument to setValue is less than or equal to 0.5 it will return True else False

Modifier and Type	Method and Description
`java.util.List<ParameterSpace>`	`collectLeaves()` Collect a list of parameters, recursively.

  - getValue
```
public java.lang.Boolean getValue(double[] input)
```
    Description copied from interface: ParameterSpace
    
    Generate a candidate given a set of values. These values are then mapped to a specific candidate, using some mapping function (such as the prior probability distribution)
    
    Specified by:
    
    getValue in interface ParameterSpace<java.lang.Boolean>
    
    Parameters:
    
    input - A set of values, each in the range [0,1], of length ParameterSpace.numParameters()
  - numParameters
```
public int numParameters()
```
    Description copied from interface: ParameterSpace
    
    Get the total number of parameters (hyperparameters) to be optimized. This includes optional parameters from different parameter subpaces. (Thus, not every parameter may be used in every candidate)
    
    Specified by:
    
    numParameters in interface ParameterSpace<java.lang.Boolean>
    
    Returns:
    
    Number of hyperparameters to be optimized
  - collectLeaves
```
public java.util.List<ParameterSpace> collectLeaves()
```
    Description copied from interface: ParameterSpace
    
    Collect a list of parameters, recursively. Note that leaf parameters are parameters that do not have any nested parameter spaces
    
    Specified by:
    
    collectLeaves in interface ParameterSpace<java.lang.Boolean>
  - getNestedSpaces
```
public java.util.Map<java.lang.String,ParameterSpace> getNestedSpaces()
```
    Description copied from interface: ParameterSpace
    
    Get a list of nested parameter spaces by name. Note that the returned parameter spaces may in turn have further nested parameter spaces. The map should be empty for leaf parameter spaces
    
    Specified by:
    
    getNestedSpaces in interface ParameterSpace<java.lang.Boolean>
    
    Returns:
    
    A map of nested parameter spaces
  - isLeaf
```
public boolean isLeaf()
```
    Description copied from interface: ParameterSpace
    
    Is this ParameterSpace a leaf? (i.e., does it contain other ParameterSpaces internally?)
    
    Specified by:
    
    isLeaf in interface ParameterSpace<java.lang.Boolean>
  - setIndices
```
public void setIndices(int... indices)
```
    Description copied from interface: ParameterSpace
    
    For leaf ParameterSpaces: set the indices of the leaf ParameterSpace. Expects input of length ParameterSpace.numParameters(). Throws exception if ParameterSpace.isLeaf() is false.
    
    Specified by:
    
    setIndices in interface ParameterSpace<java.lang.Boolean>
    
    Parameters:
    
    indices - Indices to set. Length should equal ParameterSpace.numParameters()
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
