Abstract: A method for generating a synthetic dataset from an original dataset includes encoding categorical features of the original dataset, embedding the encoded dataset in a low-dimensional space, selecting a seed record from the embedded dataset, identifying a plurality of nearest neighbor records to the seed record, generating a new record by randomly selecting features from the plurality of nearest neighbor records, and concatenating the new record into the synthetic dataset. For a synthetic dataset that contains N records, which may be the same as or different from the number of records in the original dataset, the selecting, identifying, generating, and concatenating operations operate a total of N times on the records in the embedded dataset.

Abstract: A system and a method for tracking a plurality of objects, including obtaining input data, estimating a number of skipping frames of the input data based on information from the input data, predicting results based on the estimating of the number of skipping frames, and correcting the predicted results.

Abstract: A method for switching channels on a video playback device, the device receiving content from a plurality of channels transmitted by a digital video distribution network, the method including establishing a context for selecting additional channels; receiving a selection for another channel; updating the context with the selection; and transmitting the selection to the device and providing the additional channels for fast channel switching.

Abstract: One embodiment of the present method and apparatus for improving data transfers in peer-to-peer networks includes receiving a search request message from a requesting node, where the search request message requests specific data. A responding node then sends a response message to the requesting node including a referral message comprising at least one referred node that is expected to have the requested data, based on knowledge of the referred node's previous incoming and outgoing data transfers. The responding node may also indicate that the responding node has the requested data. In addition to increasing the requesting node's view of the peer-to-peer network, this also enables the identification of nodes (e.g., referred nodes) with which the requesting node may wish to establish direct peer-to-peer connections, e.g., to build peer-to-peer communities of nodes having similar interests.

Abstract: In one embodiment, the present invention is a method and apparatus for dynamic domain-independent system parameter configuration. One embodiment of an inventive method for modifying a current system configuration to achieve a given system objective includes receiving a new system objective. The current system configuration is then modified to achieve the new system objective by applying at least one case history representing past system behavior.

Abstract: A policy for a computer system is transformed into a plurality of sub-policies, at least one synchronization step, and a final action. The sub-policies are distributed to corresponding sub-components in the computer system. The sub-policies are evaluated, wherein each sub-component evaluates its corresponding one or more sub-policies as other sub-components evaluate their corresponding one or more sub-policies. The sub-policies are synchronized by using the at least one synchronization step. The final action is performed in response to synchronizing the sub-policies. The computer system can be singular or distributed.

Abstract: This invention provides methods and apparatus for validating that transformations that are expected to occur in an IP network are indeed occurring as expected. Generally, these transformations establish logical communication tunnels within an IP network between the devices that perform the transformation and the devices that perform the reverse transformation. The invention is useful to validate the configuration of devices that support a variety of IP transformation methods, including IP-security protocols using the standard Encrypted Secure Payload protocol and Authenticated Header protocols as defined by the IETF. The invention is particularly useful to validate cases in which transformations occur on the full path of a packet traversing between two machines in an IP network, or when the transformations only occur on part of this path.
