  2. Lambda lifting - Wikipedia

    en.wikipedia.org/wiki/Lambda_lifting

    The Lambda Drop meta function performs the reverse by first converting recursive equations to lambda abstractions, and then dropping the resulting lambda expression, into the smallest scope which covers all references to the lambda abstraction. Lambda dropping is performed in two steps, Sinking; Parameter dropping

  3. Nested function - Wikipedia

    en.wikipedia.org/wiki/Nested_function

    In PHP and other languages, the lambda is an alternative. A function is defined in a code statement rather than declared with the usual function syntax. It has no name but is callable via a function reference. Such functions can be defined inside of a function as well as in other scopes. To use local variables in the anonymous function, use ...

  4. System F - Wikipedia

    en.wikipedia.org/wiki/System_F

    System F (also polymorphic lambda calculus or second-order lambda calculus) is a typed lambda calculus that introduces, to simply typed lambda calculus, a mechanism of universal quantification over types. System F formalizes parametric polymorphism in programming languages, thus forming a theoretical basis for languages such as Haskell and ML

  5. Fixed-point combinator - Wikipedia

    en.wikipedia.org/wiki/Fixed-point_combinator

    (Here we use the standard notations and conventions of lambda calculus: Y is a function that takes one argument f and returns the entire expression following the first period; the expression . ( ) denotes a function that takes one argument x, thought of as a function, and returns the expression ( ), where ( ) denotes x applied to itself ...

  6. Alpha beta filter - Wikipedia

    en.wikipedia.org/wiki/Alpha_beta_filter

    Set the initial values of state estimates x and v, using prior information or additional measurements; otherwise, set the initial state values to zero. Select values of the alpha and beta correction gains. Update. Repeat for each time step ΔT: Project state estimates x and v using equations 1 and 2; Obtain a current measurement of the output value

  7. Conjugate gradient method - Wikipedia

    en.wikipedia.org/wiki/Conjugate_gradient_method

    A comparison of the convergence of gradient descent with optimal step size (in green) and conjugate vector (in red) for minimizing a quadratic function associated with a given linear system. Conjugate gradient, assuming exact arithmetic, converges in at most n steps, where n is the size of the matrix of the system (here n = 2).

  8. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    Java's lambda expressions are just syntactic sugar. Anything that can be written with a lambda expression can be rewritten as a call to construct an instance of an anonymous inner class implementing the interface, [ a ] and any use of an anonymous inner class can be rewritten using a named inner class, and any named inner class can be moved to ...

  9. Lambda expression - Wikipedia

    en.wikipedia.org/wiki/Lambda_expression

    Lambda expression may refer to: Lambda expression in computer programming, also called an anonymous function , is a defined function not bound to an identifier. Lambda expression in lambda calculus , a formal system in mathematical logic and computer science for expressing computation by way of variable binding and substitution.
