Abstract: Techniques for evaluating an output of a machine learning model and using the evaluation to retrain the machine learning model are described. For example, a data set that is output from a layer of the machine learning model is reduced to a 2-D or 3-D representation that is suitable for viewing. A user views the reduced data set in a viewing environment such as virtual reality or augmented reality. The user makes changes using that viewing environment. The changes are then used to retrain the machine learning model.

Abstract: An invertible tapping block having first and second opposed sides each configured to be struck with an impacting member, and a web between the sides, the web having upper and lower support surfaces to which a handle is selectively attached, and the web including opposed projections, different from each other, and configured to engage different configurations of flooring planks.

Abstract: Responsive to determining that a quality of a V2V connection between a host vehicle and a target does not satisfy a threshold, a following position of the host vehicle relative to the target and whether the following position is within a predicted null position of the V2V connection and closer to the target than a selected position are determined. The following position is then controlled based on whether the following position is within the predicted null position and whether the following position is closer to the target than the selected position. By controlling the following position based on the quality of the V2V connection and the null position, more-reliable V2V connections may be maintained, thus enabling better performance of downstream operations.

Abstract: Systems, methods, and products for identifying IP mass hosts and determining whether they are good or bad. One embodiment is a method including selecting a first candidate IP address, identifying a set of domains hosted at the IP address, and identifying registrants of the domains. A number of unique ones of the registrants is determined and if the number of unique registrants exceeds a threshold number, the candidate IP address is deemed an IP mass host. Otherwise, the candidate IP address is deemed not to be an IP mass host. For an IP mass host, domains that have bad reputations are identified, and it is determined whether the bad domains comprise at least a threshold percentage of the total hosted domains. If the IP mass host has at least the threshold percentage of bad domains, the IP mass host is deemed a bad mass host.

Abstract: A system and method for updating patient devices is disclosed. The patient devices may include respiratory therapy devices that operate in accordance with instruction sets, such as software or firmware. A server may maintain a database of configuration data indicating the versions of the software and firmware that is currently installed on the patient devices. The server may also transmit updated instructions from over a network, including a wireless network. Particular patient devices may be selected for updating based on the configuration data. Upon performing an update a patient device may transmit configuration data to the server.

Abstract: Machine learning techniques are employed to model test runs of an automated test platform in ways that allow for reliable identification of various types of test behavior such as, for example, whether certain classes of failures can be characterized as test flake.

Abstract: A computer implemented method of generating a scenario to be run in a simulation environment for testing the behaviour of an autonomous vehicle is described. An image is rendered on a display. A user can mark multiple locations to create at least one path for an agent vehicle in the rendered image. A path is generated which passes through the locations and rendered on the display. A user can define at least one behavioural parameter for controlling behaviour of the agent vehicle associated with the at least one path when the scenario is run in a simulation environment. The scenario is recorded for future use.

Abstract: A light source unit generates an optical signal out of a bend-insensitive (“BI”) optical fiber that is compliant with a desired encircled flux (“EF”). The unit includes a light source to generate an optical light signal and a conventional multimode optical fiber coupled to receive the optical light signal from the light source at a first end. A modal conditioner is arranged to condition the optical light signal propagating along different modes of the conventional multimode fiber. A first bend-insensitive (BI) multimode optical fiber has an input end, the input end of the first BI multimode optical fiber being coupled at a second end of the conventional multimode optical fiber to receive the conditioned optical light signal from the conventional multimode fiber. The output from the first BI multimode optical fiber outputs an optical signal having the desired EF.

The wall has a first Layer A comprising an outer surface of the wall, a second Layer A comprising the inner surface of the wall and a Layer B between the first and second Layer As. The B layer can contain an effect pigment and/or an opacifying pigment and the Layer As can be transparent. The wall contains a deboss element.

Abstract: Various embodiments of a system and method for a quantitative approach and departure risk assessment are described. In one example, the system includes program instructions executable in the computing device that, when executed by the computing device, cause the computing device to: obtain a nominal flight path of an aircraft, calculate a potential crash area for a section of the nominal flight path based on a failure mode, calculate risk values based on a population data of a geographical area traveled corresponding to the nominal flight path, and display the calculated risk values plotted on a map of at least a section of the geographical area traveled corresponding to the nominal flight path. Other examples include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.

Abstract: The present disclosure relates to systems, methods, and computer-readable media for enhancing security of communications between instances of clients and servers while enabling rotation of server certificates (e.g., X.509 certificates). The systems described herein involve updating a client list of server certificates (e.g., a certificate thumbprint) without reconfiguring or re-installing a client and/or server application, starting a new session (e.g., a hypertext transfer protocol secure (HTTPS) session), or deploying new code. The systems described herein may passively or actively update a client list of certificates to enable a client to security verify an identity of a server instance in a non-invasive way that boosts security from man-in-the-middle types of attacks.
