Abstract Value Members

abstract def combination(that: Factor[T], op: (T, T) ⇒ T): Factor[T]

Combination function for factors.
Combination function for factors. By default, this is product, but other operations (such as divide that is a valid operation for some semirings) can use this
abstract def contentsContains(index: List[Int]): Boolean

Test whether a factor contains a value for a specific index
abstract def createFactor[T](parents: List[Variable[_]], output: List[Variable[_]], _semiring: Semiring[T] = semiring): Factor[T]

Creates a new factor of the same type
abstract def deDuplicate(): Factor[T]

Returns a new Factor with duplicate variable(s) removed
abstract def fillByRule(rule: (List[Extended[_]]) ⇒ T): Factor[T]

Fill the contents of this factor by applying a rule to every combination of values.
abstract def get(indices: List[Int]): T

Get the value associated with a row.
Get the value associated with a row. The row is identified by an list of indices into the ranges of the variables over which the factor is defined.
abstract def getContents(): Traversable[T]

Get the contents of a factor as a traversable (note: no indicies provided)
abstract def mapTo[U](fn: (T) ⇒ U, _semiring: Semiring[U] = semiring): Factor[U]

Fill the contents of the target by applying the given function to all elements of this factor.
abstract def marginalizeToWithSum(sum: (T, T) ⇒ T, targets: Variable[_]*): Factor[T]

Returns the marginalization of the factor to a variable according to the given addition function.
Returns the marginalization of the factor to a variable according to the given addition function. Unlike marginalizeTo, this uses the provided sum function. This is useful e.g. to easily switch between max-product and sum-product operations when the data within are unchanged and the product operation is the same.
The returned factor uses the semiring associated with this factor; it does not override the sum function of the semiring with the function given here.
abstract def output: List[Variable[_]]
abstract def parents: List[Variable[_]]
abstract def product(that: Factor[T]): Factor[T]

Returns the product of this factor with another factor according to a given multiplication function.
Returns the product of this factor with another factor according to a given multiplication function. The product is associated with all variables in the two inputs, and the value associated with an assignment is the product of the values in the two inputs.
abstract def recordArgMax[U](variable: Variable[U], comparator: (T, T) ⇒ Boolean, _semiring: Semiring[U] = semiring.asInstanceOf[Semiring[U]]): Factor[U]

Returns a factor that maps values of the other variables to the value of the given variable that maximizes the entry associated with that value, according to some maximization function.
Returns a factor that maps values of the other variables to the value of the given variable that maximizes the entry associated with that value, according to some maximization function. comparator defines the maximization. It returns true iff its second argument is greater than its first.
U
The type of element whose value is being recorded. The resulting factor maps values of other variables in this factor to this type.
abstract def semiring: Semiring[T]
abstract def set(indices: List[Int], value: T): Factor[T]

Set the value associated with a row.
Set the value associated with a row. The row is identified by an list of indices into the ranges of the variables over which the factor is defined.
abstract def stringContents(): String

Return the contents of a factor as a string
abstract def sumOver(variable: Variable[_], sum: (T, T) ⇒ T = semiring.sum): Factor[T]

Returns the summation of the factor over a variable according to an addition function.
Returns the summation of the factor over a variable according to an addition function. The result is associated with all the variables in the input except for the summed over variable and the value for a set of assignments is the sum of the values of the corresponding assignments in the input.
If no funciton is provided, this defaults to the sum function in this factor's semiring.
abstract def toReadableString: String

Produce a readable string representation of the factor
