摘要： Various technologies described herein pertain to computing top-K pairwise co-occurrence statistics using an upper bounding heuristic. Upper bound values of a co-occurrence statistic for items in a set can be computed based on a query item, and items can be sorted into an order. The items and the query item are represented by respective portions of a tensor. An item from the order associated with a highest upper bound value can be selected, an actual value of the co-occurrence statistic can be computed for the selected item, the upper bound value for the selected item can be replaced with the actual value for the selected item, and the selected item can be repositioned in the order. When the top-K items in the order lack an item associated with an upper bound value, the top-K items and actual values of the co-occurrence statistic for the top-K items can be outputted.

摘要： The claimed subject matter provides systems and/or methods that combat identity follow-on attacks. The system can include components for receiving a plurality of security configuration changes, selecting which of the changes included in the plurality of security changes to approve or disapprove, and based on which of the changes are approved or disapproved by an administrator, generating a further plurality of security configuration changes that the administrator can once again approve or disapprove until the administrator is satisfied with the security configuration changes.
