摘要:
The present invention provides a system and method for optimizing routes that include multiple stops. This is accomplished by allowing users to identify a starting point, a destination, and types of businesses or other locations to be visited along the way. A route processor then provides users with a list of stores or other requested detour choices yielding a trip of optimal itinerary. The detour choices may be either an ordered sequence or an unordered set of points to be visited and may include constraints that make it possible to optimize utility functions according to user preferences.

A method, system and computer program product for confirming the validity of data returned from a data store. A data store contains a primary data set encrypted using a first encryption and a secondary data set using a second encryption. The secondary data set is a subset of the primary data set. A client issues a substantive query against the data store to retrieve a primary data result belonging to the primary data set. A query interface issues at least one validating query against the data store. Each validating query returns a secondary data result belonging to the secondary data set. The query interface receives the secondary data result and provides a data invalid notification if data satisfying the substantive query included in an unencrypted form of the secondary data result is not contained in an unencrypted form of the primary data result.

A computer implemented method, system, and computer usable program code for classifying a data stream using high-order models. The data stream is divided into a plurality of data segments. A classifier is selected for each of the plurality of data segments. Each of a plurality of classifiers is clustered into states. A state transition matrix is computed for the states. The states of the state transition matrix specify one of the high-order models for classifying the data stream.

A system and method for learning models from scarce and/or skewed training data includes partitioning a data stream into a sequence of time windows. A most likely current class distribution to classify portions of the data stream is determined based on observing training data in a current time window and based on concept drift probability patterns using historical information.

A method comprises receiving a first virtual machine image, processing the first virtual machine image with a Mirage transformation, and generating a first manifest including a mapping of hierarchical names of content of the first virtual machine image to content identifiers.

A method for managing a virtual machine image includes receiving a request to change a package configuration of a machine, processing an image action received in the request, wherein the processing the image action received includes, opening the image action with associated action inputs, comparing the opened image action inputs with inputs associated with action instances in a database, determining whether the compared opened image action inputs match the inputs associated with action instances, retrieving from the database, image difference data associated with the image action responsive to determining that the compared opened image action inputs match the inputs associated with action instances in the database, and applying the image difference data to an image to transform the image, determining whether each image action in the request has been processed and processing a second image action responsive to determining that each image action has not been processed.

A method for operating a file system includes receiving a write instruction including a file descriptor associated with a file and a content identifier, a content offset, and a content length, associating a region within the file with the content identifier, saving the association of the region and the content identifier.
