Abstract: A method, including receiving, from multiple sources, respective sets of incidents, and respective suspiciousness labels for the incidents. A set of rules are applied so as to assign training labels to respective incidents in a subset of the incidents in the received sets. For each given incident in the subset, the respective training label is compared to the respective suspiciousness label so as to compute a respective quality score for each given source. Any sources having respective label quality scores meeting a predefined criterion are identified, and a model for computing predicted labels is fit to the incidents received from the identified sources and the respective suspiciousness labels of the incidents. The model is applied to an additional incident received from one of the sources to compute a predicted label for the additional incident, and a notification of the additional incident is prioritized in response to the predicted label.

Abstract: The technology disclosed in this patent document can be used to implement an optical device for generating broadband optical pulses, including an optical waveguide having different waveguide structures at different locations along the optical waveguide and with varying dimensions or pressure gradient that change adiabatically along the different locations to enable non-linear four wave mixing over a broad spectral range.

Abstract: A system for frequency conversion, comprises a laser source and a harmonic generation crystal. The laser source is configured to produce optical pulse energy of less than 100 ?J. The harmonic generation crystal comprises a structure characterized by a nonlinear susceptibility, and a crystal grating period which adiabatically varies along the longitudinal direction in a manner that the crystal grating period is inversely proportional to a crystal grating function of a coordinate z measured along the longitudinal direction.

Abstract: Methods, apparatus and computer software products implement embodiments of the present invention that include protecting a computing system by defining a list of network access messages that are indicative of human use of computing devices, and extracting, from data traffic transmitted over a data network connecting a plurality of the computing devices to multiple Internet sites, respective transmissions from the computing devices to the Internet sites. A given transmission including one of the network access messages in the list is detected in the transmissions from a given computing device, and the given computing device is classified as being operated by a human in response to detecting the given transmission. Upon identifying suspicious content in the transmissions from a subset of the computing devices that includes the given computing device, any suspicious transmissions from the given computing device are ignored in response to the classification.
