- All Implemented Interfaces:
- Serializable, Comparable<StochasticCalculateMethods>
public enum StochasticCalculateMethods
- extends Enum<StochasticCalculateMethods>
This enumeratin was created to organize the selection of different methods for stochastic
calculations. It was also created for use with Stochastic Meta Descent (SMDMinimizer) due
to the need for Hessian Vector Products, and the inefficiency of continuing to calculate these
vector products in other minimization methods like Stochastic Gradient Descent (SGDMinimizer)

values
public static final StochasticCalculateMethods[] values()
- Returns an array containing the constants of this enum type, in
the order they're declared. This method may be used to iterate
over the constants as follows:
for(StochasticCalculateMethods c : StochasticCalculateMethods.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they're declared
valueOf
public static StochasticCalculateMethods valueOf(String name)
- Returns the enum constant of this type with the specified name.
The string must match exactly an identifier used to declare an
enum constant in this type. (Extraneous whitespace characters are
not permitted.)
- Parameters:
name
- the name of the enum constant to be returned.
- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant
with the specified name
