    Abstract: A method for multicategory classification of streaming data records includes receiving a list of signature rules, each comprising a Boolean expression of a set of atomic recognizers (ARs) of one or more input fields of an input record and an assignment of a signature if the Boolean expression evaluates to TRUE, generating a list of all signature contexts from the list of signature rules, generating a context lookup table for each context, and processing a stream of input records on which signature detection is performed by using said ARs, said list of signature contexts, and said context lookup table for each context, wherein each input record in the stream of input records is classified into one of a plurality of categories based on the signature detection result, wherein an amount of processing grows sublinearly with a number of signature rules being processed.

    Abstract: A system and method are provided for discovering k-nearest-neighbors to a given point within a certain distance d. The method includes constructing an index of geometries using geohashes of geometries as an indexing key to obtain an indexed set of geometries, and calculating a geohash representation of the given point with a resolution equal to a magnitude value of d. The method includes searching for a closest-prefix geometry from the indexed set using the geohash representation of the given point, and identifying geometries from the indexed set having a same prefix as the closest-prefix geometry. The method further includes calculating distances between the given point and the geometries identified from the indexed set having the same prefix as the closest-prefix geometry, and determining k geometries with respective shortest distances less than d from the geometries identified from the indexed set having the same prefix as the closest-prefix geometry.

    Abstract: Middleboxes include a processor configured to determine that a network connection between a client device and a server device is idle. A connection table is configured to create a first connection entry at the middlebox for the client device and a second connection entry at the middlebox for the server device. The first and second connection entries are initialized after determining that the network connection between the client device and the server device is idle. A network control module is configured to activate redirection of the network connection between the client device and the server device to the middlebox after determining that the network connection between the client device and the server device is idle.

    Abstract: In an approach, a processor trains a statistical classifier and a set of micro classifiers. A processor receives an input to be classified by the statistical classifier. A processor receives a label assigned to the input by the statistical classifier and respective labels assigned by each micro classifier of the set of micro classifiers. A processor determines that the label assigned by the statistical classifier is the same as at least one label assigned by at least one micro classifier of the set of micro classifiers. A processor generates a natural language explanation for assigning the label using the at least one micro classifier and the label. A processor outputs the label and the natural language explanation to a user of a computing device. A processor receives user feedback from the user in the form of an acceptance or a rejection of the natural language explanation.

    Abstract: Methods for inserting a middlebox into a network connection include monitoring network state information in a connection between a client and a server. When the connection is idle, a connection entry is created for each device and is initialized using state information gathered by monitoring the network connection. Redirection of the network connection is activated between the client and the server such that the middlebox mediates the connection. Methods for removing a middlebox from a network connection include determining a degree of mismatch between a sequence number in a first connection between the middlebox and a client and a sequence number in a second connection between the middlebox and a server, delaying acknowledgment signals from the middlebox on a connection to decrease the degree of mismatch, and establishing a direct connection between the client and the server without mediation by the middlebox when the degree of mismatch is zero.
