Abstract: A computer-implemented method of training a network anomaly detection system is disclosed. The method involves generating synthetic benign network data and synthetic anomalous network data and combining the synthetic benign network data and synthetic anomalous network data to generate combined synthetic network data having a predetermined density of anomalous network data. The combined synthetic network data is provided to a trained anomaly detection model, and an accuracy score is determined that is representative of how accurately the trained anomaly detection model recognizes anomalous activity in the combined synthetic network data. If the accuracy score is less than a threshold value, the anomaly detection model is trained with additional network data and a new accuracy score is determined. Otherwise, the predetermined density of anomalous network data is reduced and a new accuracy score is determined until a predetermined stopping criterion is met.

Abstract: Methods and apparatuses for manipulating the temperature of a surface are provided. Devices of the present disclosure may include a thermal adjustment apparatus, such as a controller in electrical communication with one or more thermoelectric materials, placed adjacent to the surface of skin. The device may generate a series of thermal pulses at the surface, for providing an enhanced thermal sensation for a user. The thermal pulses may be characterized by temperature reversibility, where each pulse includes an initial temperature adjustment, followed by a return temperature adjustment, over a short period of time (e.g., less than 120 seconds). The average rate of temperature change upon initiation and upon return may be between about 0.1° C./sec and about 10.0° C./sec. In some cases, the average rate of the initial temperature adjustment is greater in magnitude than the average rate of the return temperature adjustment.

Abstract: Examples of the present disclosure describe systems and methods relating to adaptive virtual services. In an example, a user specifies a device configuration for a platform device. As a result, a service provider installs selected virtual-network functions and defines network connections as specified by the device configuration. Management software may also be installed, thereby enabling the service provider to communicate with and remotely manage the platform device. The installed virtual-network functions are activated on the platform device once it is delivered to the user. In some instances, the user changes the device configuration. For example, the user may install new virtual-network functions, reconfigure or remove existing virtual-network functions, or change defined network connections. As a result, the service provider reconfigures the platform device accordingly. Thus, the user need not purchase new specialized hardware in order to change the available functions of the computer network.

Abstract: The present disclosure describes systems and apparatus for detecting an impending sewer backup by detecting fluid undulations of predetermined magnitude inside a main body of a backwater valve. When at least a predetermined number of fluid undulations of predetermined magnitude are detected within a predetermined time period, an alarm can be triggered. Such undulations can be detected by monitoring a buoyant gate in a normally-open backwater valve to detecting instances of movement of the gate from a lowered position in which fluid flow from an inlet through the backwater valve is unobstructed by the gate toward but stopping short of a raised position in which the gate closes the inlet to obstruct fluid flow through the valve. For example, a sensor can be carried on the gate to detect movement of the gate. Alternatively, fluid levels inside the main body can be monitored directly.
