Abstract: A machine translation system capable of clustering training data and performing dynamic domain adaptation is disclosed. An unsupervised domain clustering process is utilized to identify domains in general training data that can include in-domain training data and out-of-domain training data. Segments in the general training data are then assigned to the domains in order to create domain-specific training data. The domain-specific training data is then utilized to create domain-specific language models, domain-specific translation models, and domain-specific model weights for the domains. An input segment to be translated can be assigned to a domain at translation time. The domain-specific model weights for the assigned domain can be utilized to translate the input segment.

Abstract: A method of payload type aware routing in wireless mesh networks comprises: identifying, by a first mesh network device of a wireless mesh network, a plurality of path selection metric types supported by the wireless mesh network; identifying, by inspecting an outgoing data frame, a path selection metric type corresponding to a payload type of the outgoing data frame; determining that the path selection metric type is comprised by the plurality of path selection metric types supported by the wireless mesh network; determining, using the path selection metric type, a network path to a destination mesh network device of the outgoing data frame, wherein the network path comprises an identifier of an intermediate mesh network device between the first mesh network device and the destination mesh network device; and transmitting the outgoing data frame to the intermediate mesh network device.

This portion of discovery configuration information may include service advertisement information, routing information for traversing the network topology, and in some embodiments, the validation token.

Abstract: A distributed in-memory query processor may utilize a remote data store. Column segments may be retrieved from the remote data store and loaded into system memory of a computing node. The query processor may, in response to receiving a request to perform a query, identify columns and ranges of column values required to process the query. Partition-level schemas and cross-partition schemas may be formed for computing nodes holding column segments in memory. Computing nodes may be selected for processing the query based on a degree to which a partition or set of partitions matches data requirements of the query.

An item in the video content is identified. The search is executed in a database to obtain information regarding the item. The information is presented to the user.

Abstract: An audio/video (A/V) recording and communication doorbell comprises a camera, a front button, and a motion sensor. The camera and the motion sensor are configured to work in tandem to detect motion in a field of view of the A/V recording and communication doorbell, such that a first one of the camera and the motion sensor detects motion and the other one of the camera and the motion sensor independently verifies the motion detection before an alert is sent to a user's client device. In this manner, user alerts from false alarm motion detections are reduced.

Abstract: Techniques are described for facilitating performance of tasks involving human review of media data (e.g., images, audio clips, video clips, etc.), such as to identify one or more targets of interest. The media data review may be performed for various reasons, such as to assist in locating one or more target objects in a large geographical area (e.g., one or more missing people or vehicles) based on human review of large quantities of images that each correspond to a small subset of the geographical area. When one or more of the reviewed media data pieces are identified as being relevant, information about those identified media data pieces may be used in various ways. Furthermore, in at least some situations, the media data review may be part of a charitable effort that uses human volunteers to review the media data without monetary payment or other compensation.

Abstract: This disclosure describes interactive data processing systems configured to facilitate selection by a human associate of tentative results generated by an automated system from sensor data. In one implementation, an event may take place in a materials handling facility. The event may comprise a pick or place of an item from an inventory location, movement of a user, and so forth. The sensor data associated with the event is processed by an automated system to determine tentative results associated with the event. In some situations, an uncertainty may exist as to which of the tentative results accurately reflects the actual event. The system may then determine whether the event is to be merged with one or more temporally and spatially proximate events and, if so, the sensor data and tentative results for the merged event is sent to a human associate. The associate may select one of the tentative results.

Abstract: A data storage system implements aggregation, bifurcation, and/or reduction techniques to improve the efficiency of processing data storage requests. Data storage requests and/or their associated payloads may be aggregated based on one or more parameters. Data to be the stored and the associated commands may be separated so as to optimize a system's throughput and latency for each. Furthermore, extraneous commands and requests may be reduced or eliminated based on heuristics associated with the requests and the data.

One of the methods includes receiving identifying information for a user device, the identifying information being received in response to the user device being within a distance of a vending machine. The vending machine can include sensors that trigger the user device to provide identifying information. A portion of profile information is accessed, portion of profile information indicating a unique identifier assigned to the user device. The portion of profile information is provided to one or more servers that communicate with the vending machine over one or more networks. Preference in formation is displayed via a display of the vending machine, the preference information being maintained by servers and being associated with the unique identifier.

Abstract: A voice assistant system may be configured to receive a spoken introduction from a trusted user to introduce a new user and designate access privileges for the new user. The voice assistant system may process the speech using automated speech recognition and may parse the text to determine intent. The voice assistant system may also analyze the speech to determine a profile associated with the speaker that spoke the introduction. The voice assistant system may determine that the trusted user includes administrative privileges. The access privileges, when granted, may allow the new user to interact with the voice assistant system, such as to issue commands, extract information, play media, and/or perform other actions with the voice assistant system, which may be unavailable to people who are not introduced to the voice assistant system by a trusted user and/or do not have the access privileges associated with a user profile.

Abstract: This disclosure describes a configuration of an unmanned aerial vehicle (“UAV”) that will facilitate extended flight duration. The UAV may have any number of lifting motors. For example, the UAV may include four lifting motors (also known as a quad-copter), eight lifting motors (also known as an octo-copter), etc. Likewise, to improve the efficiency of horizontal flight, the UAV also includes a pivot assembly that may rotate about an axis from a lifting position to a thrusting position. The pivot assembly may include two or more offset motors that generate a differential force that will cause the pivot assembly to rotate between the lifting position and the thrusting position without the need for any additional motors or gears.

Abstract: Systems and methods are provided for facilitating automated video scripting, Video frames may be analyzed to determine scores indicative of the association between a characteristic of the video frame and an attribute of a theme associated with a particular person.

Abstract: A log-structured data store may implement efficient garbage collection. Log records may be maintained in data blocks according to a log record sequence. Based, at least in part, on a log reclamation point, the log records may be evaluated to identify data blocks to reclaim that have log records in the log sequence prior to the log reclamation point. New versions of data pages updated by log records in the identified data blocks may be generated and stored in base page storage for the log structured data store. The identified data blocks may then be reclaimed for storing new data.

Abstract: A management controller may request units of diagnostic information from a BIOS of the management controller's host computing device. The management controller may trigger an interrupt, in response to which the BIOS, by the execution of a processor of the host, may cause the diagnostic information to be copied to a video memory of the management controller. Upon the completion of the interrupt handler, a graphics controller of the management controller may cause the diagnostic information to be transferred to a non-volatile memory, and transferred out-of-band to a client device.

Abstract: In distributed processing frameworks, compute instance and cluster failure can occur due to a master node running out of disk space as a result of file system logs. An application employs a disk space manager to detect and manage available disk space based on a set of configurable directories. The disk space manager prevents a compute instance from reaching a threshold of capacity due to improper or malfunctioning component logging.
