    Abstract: Disclosed are methods and apparatuses for classifier evaluation. The evaluation involves constructing a ground truth refinement having a degree of error within specified bounds from a malware reference dataset as an approximate ground truth refinement. The evaluation further involves using the approximate ground truth refinement to determine at least one of: a lower bound on precision or an upper bound on recall and accuracy. The evaluation further involves evaluating a classifier by evaluating at least one of a classification method or clustering method by examining changes to the upper bound and/or the lower bound produced by the approximate ground truth refinement.

    Abstract: Exemplary systems and methods are directed to risk-based observability of a platform. Data is received from plural devices from one or more computing environments on a network. The received data is in a raw data format according to the computing environment or platform from which it was received. The received data is converted from the raw format to a structured format. The converted data is enhanced by adding contextual information associated with a corresponding one of the plural devices. A risk analysis is performed on the enhanced data based on one or more risk detection rules applied to the network. One or more tags are applied to the enhanced data based on results of the risk analysis. Data analysis is performed on the enhanced data to identify devices from aggregate sources. The data is sent to one or more destinations on the network based on the applied tags.

    Abstract: A thermal management system includes an open-circuit refrigeration system having an open-circuit refrigerant fluid flow path. The open-circuit refrigeration system includes a receiver configured to store a refrigerant fluid, an evaporator configured to receive the refrigerant fluid at an evaporator inlet and to extract heat from a heat load that contacts the evaporator, and provide refrigerant vapor at an evaporator outlet. The open-circuit refrigeration system also includes a vapor pump device having a vapor pump inlet that receives the refrigerant vapor and having a vapor pump outlet that outputs compressed refrigerant vapor to an exhaust line coupled to the vapor pump outlet, with the receiver, the evaporator, the vapor pump device, and the exhaust line connected in the open-circuit refrigerant fluid flow path.

    Abstract: A method and system for configuring a computer for data classification using ordinal regression includes: receiving and storing a data set having data with a plurality of data features that have an ordinal relationship; generating a plurality of ordinal classification bins based on the relationship of the data features, at least one ordinal classification bin having walls defined by at least two hyperplanes; generating an ordinal regression model of the data set illustrating the data of the data set arranged into the plurality of ordinal classification bins; and tuning the slopes of the walls of the at least one ordinal classification bin based on the relationships between the plurality of data features of the data arranged within the at least one ordinal classification bin such that the slopes of the two hyperplanes defining the walls of the at least one ordinal classification bin are not parallel.

    Abstract: Described is a directed energy system that has a compact and modular configuration and that enables movement/assembly by a two-user team. The directed energy system includes one or more high-power laser sources that house one or more high-power fiber amplifiers, a beam combiner optically coupled to the one or more high-power laser sources, a beam director coupled to the beam combiner, a command and control module configurable to control operation of the one or more high-power fiber amplifiers. The directed energy system also includes a handheld controller with an integrated monitor, the handheld controller configurable to send control signals to the handheld controller module to control operation of the handheld controller module and a power module that includes batteries and power converters that provide electrical power required to run the directed energy system. Cooling of the directed energy system is performed only by ambient air contacting the directed energy system and without application of any external coolant medium to the system.
