Method Detail

• getValue

  public ISchedule getValue(double[] parameterValues)

  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<ISchedule>

  Parameters:

  parameterValues - 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<ISchedule>

  Returns:

  Number of hyperparameters to be optimized

• collectLeaves

  public 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<ISchedule>

• getNestedSpaces

  public Map<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<ISchedule>

  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<ISchedule>

• 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<ISchedule>

  Parameters:

  indices - Indices to set. Length should equal ParameterSpace.numParameters()
