IT disaster recovery - IT disaster recovery is the planned restoration of technology services and data after a major disruption.
IT operations analytics - IT operations analytics (ITOA) is the use of analytical methods on operational technology data to understand, troubleshoot and improve IT services.
IT risk - IT risk is the possibility that uncertainty involving information technology will affect an organization's objectives.
IT risk management - IT risk management is the ongoing process of identifying, assessing, responding to, and monitoring risks arising from an organization's use of information...
Item-item collaborative filtering - Item-item collaborative filtering is a recommendation approach that uses relationships between items inferred from users' interactions or ratings.
Item matrix - An item matrix is a collection of learned item representations used in a matrix-factorization recommender.
Item response theory - Item response theory (IRT) is a family of statistical models that relates responses to individual questions or tasks to an unobserved ability or trait and...
Item stem and leaf plot - An item stem and leaf plot is a questionnaire display that places question identifiers at positions corresponding approximately to their average scores on a...
Item-total correlation - Item-total correlation measures the association between responses to one questionnaire or test item and a score formed from a set of items.
Item tree analysis - Item tree analysis, or ITA, is an exploratory method for investigating hierarchical relationships among questionnaire or test items from response patterns.
Iterated extended Kalman filter - The iterated extended Kalman filter refines an extended Kalman filter's measurement update by repeatedly linearizing the observation model around an...
Iterated local search - Iterated local search is an optimization framework that repeatedly improves a solution locally, perturbs it, improves the perturbed solution, and decides...
Iteration - An iteration is one complete round of an improvement process: one training update, one tuning cycle or one review pass, after which the result is measured...
Iterative deepening search - Iterative deepening search repeatedly performs depth-limited depth-first searches with increasing depth limits until it finds a goal or establishes failure.
Iterative expansion - Iterative expansion, or IE, is a memory-bounded heuristic search algorithm developed by Stuart Russell.
Iterative method - An iterative method is a numerical procedure that constructs a sequence of approximate answers by repeatedly applying an update rule.
Iterative rational Krylov algorithm - The iterative rational Krylov algorithm, or IRKA, constructs a smaller linear dynamical model by repeatedly updating interpolation points using the poles of...
Iterative soft thresholding algorithm - The iterative soft thresholding algorithm, often called ISTA or iterative shrinkage-thresholding, solves certain optimization problems by alternating a...
