trait Semiring[T] extends AnyRef

Operations in factored algorithms are defined by a semiring algebraic structure. Each semiring defines a product and sum operation, and a value for zero and one which satisfy a set of properties. Different semirings are appropriate for certain algorithms and data types.

Abstract Value Members

  1. abstract val one: T

    A value such that a*1 = a

  2. abstract def product(x: T, y: T): T

    Product of two entries, as defined by the particular inference problem.

  3. abstract def sum(x: T, y: T): T

    Sum of two entries, as defined by the particular inference problem.

    Sum of two entries, as defined by the particular inference problem. E.g., for computing conditional probabilities, sum is ordinary addition; for most probable explanation, it is max.

  4. abstract val zero: T

    A value such that a + 0 = a
