摘要： Performing adaptive cyber-security analytics including a computer implemented method that includes receiving a report on a network activity. A score responsive to the network activity and to a scoring model is computed at a computer. The score indicates a likelihood of a security violation. The score is validated and the scoring model is automatically updated responsive to results of the validating. The network activity is reported as suspicious in response to the score being within a threshold of a security violation value.

摘要： A method for speech recognition, the method includes: extracting time-frequency speech features from a series of reference speech elements in a first series of sampling windows; aligning reference speech elements that are not of equal time span duration; constructing a common subspace for the aligned speech features; determining a first set of coefficient vectors; extracting a time-frequency feature image from a test speech stream spanned by a second sampling window; approximating the extracted image in the common subspace for the aligned extracted time-frequency speech features with a second coefficient vector; computing a similarity measure between the first and the second coefficient vector; determining if the similarity measure is below a predefined threshold; and wherein a match between the reference speech elements and a portion of the test speech stream is made in response to a similarity measure below a predefined threshold. The said reference speech elements correspond to a keyword of interest, wherein Simultaneous Orthogonal Matching Pursuit (SOMP) is used in their alignment.

摘要： A keyed delay is used in the processing of streaming data to decrease the processing performed and the output provided. A first event, within a particular window, having a particular key starts a delay condition. Arriving events with the same key replace the previous arrival for that key until the delay condition is satisfied. In response thereto, the latest event with that key is output.

摘要： A system and method for dynamically building applications for stream processing includes providing processing elements with a flow specification describing each input and a stream description describing each output such that the flow specification indicates a stream or streams which are to be received based on processing information and the stream descriptions indicate the processing information. Processing elements that can be reused are identified by determining equivalence between the processing elements. Processing elements that are new and are not reusable are instantiated in a flow graph. An application is dynamically composed, using the instantiated processing elements by routing available streams to the instantiated processing elements in accordance with the flow specifications.
