Abstract: A materialized view management service (MVMS) is capable of monitoring resource allocation changes of a source data object at a source data store and responsively generating resource change alerts to the owner of a target data object (the materialized view) in the target data store. Resource allocation changes may include autoscaling changes to the source data object's partition scheme, throughput limit, storage limit, and the like. The MVMS generates resource change alerts in response to these detected events and pushes the alerts to interested subscribers. Depending on the embodiment, the alerts may be pushed to human administrators, or the target data store itself, which may be configured to automatically adjust the resource allocation of the target data object to match the source data object. Advantageously, the disclosed alerts allow view owners to gain real time visibility of resource auto-scaling at the data source and appropriately react to such changes.

Abstract: Systems and techniques for generation, storage, and updating of common floor plans across shared autonomous mobile devices. The systems and techniques include extraction of semantically meaningful data from one or more occupancy maps to provide a floorplan to a user that aligns with the user's understanding of the space using heuristics and machine learning techniques. The techniques also enable repair of damaged or inconsistent floor plan geometries through the use of polygon triangulation and graph cuts.

Abstract: A speech recognition platform configured to receive an audio signal that includes speech from a user and perform automatic speech recognition (ASR) on the audio signal to identify ASR results. The platform may identify: (i) a domain of a voice command within the speech based on the ASR results and based on context information associated with the speech or the user, and (ii) an intent of the voice command. In response to identifying the intent, the platform may perform multiple actions corresponding to this intent. The platform may select a target action to perform, and may engage in a back-and-forth dialog to obtain information for completing the target action. The action may include streaming audio to the device, setting a reminder for the user, purchasing an item on behalf of the user, making a reservation for the user or launching an application for the user.

Abstract: A system is described that combines outputs of network simulations, which are used for capacity planning, with empirical data of network element failure probabilities, to produce what traffic utilization is needed for each network device interface to achieve a specified availability target. Utilization of each interface can be captured for each failure case simulated. From this failure data, the utilization distribution for each link can be produced, across all failure cases. This utilization-by-failure data from simulation is combined with the empirical mean-time between failure (MTBF) and mean-time to recovery (MTTR) of each failure from the span reliability data set. This allows for a prediction of what percentage of time the interface is utilized. Thus, a relationship is established between the capacity provisioned and the percentage of time that the capacity will be uncongested. Network devices can then be added to the network to establish the availability target.

In such orchestration environments, virtual domain control units and/or virtual electronic control units are implemented that execute code included in the vehicle code packages. In some embodiments, such virtual domain control units or virtual electronic control units allow computing capacity and/or data storage capacity of a vehicle to be augmented via remotely implemented virtual domain control units and/or remotely implemented virtual electronic control units.

Abstract: A device capable of using data from multiple sensors to determine an estimated position/direction of a user with respect to the device. The device may use estimated position data, along with confidence data, that originated from a plurality of sensors to fuse the data to determine the user's estimated position and comprehensive confidence of the estimated position. The system may use the location information to perform beamforming/beam steering and/or other downstream operations using the comprehensive estimated position.

Abstract: Inferences may be obtained to handle access requests at a non-relational database system. An access request may be received at a non-relational database system. The non-relational database system may determine that the access request uses a machine learning model to complete the access request. The non-relational database system may cause an inference to be generated using data items for the access request as input to the machine learning model. The access request may be completed using the generated inference.

The first imaging device is oriented in a first direction, the second imaging device is oriented in a second direction that is different than the first direction, and the third imaging device is oriented in the second direction.

Abstract: An event deduplication system may efficiently perform event deduplication (identifying “new” or “unique” events that might be an anomaly) by using a first stage that has multiple first stage processes running in parallel (e.g., at different data centers) and a single second stage that has a second stage process that receives and processes events from the different first stage processes. The second stage process updates a global state (e.g., lookup table) and periodically publishes the global state to the first stage processes to update their local state. When the second stage process receives a possible new event from a first stage process, it may more accurately determine whether the event is actually a new event based on the global state.

Abstract: Methods and apparatus for interfaces to manage inter-regional connectivity for direct network peerings. A system may include a connectivity coordinator, a first resource collection in a first geographical zone and a second resource collection in a second geographical zone. The coordinator implements a programmatic interface defining connectivity operations. The coordinator receives a request via the interface to establish a logically isolated network path to the second resource collection on behalf of a client that has a dedicated physical link set up to connect to the first resource collection. In response to the request, the coordinator performs one or more configuration operations to enable traffic to flow from the client's network to the second resource collection over a logically isolated network path using the dedicated physical link.

Abstract: A system and method for providing quantum entanglement-as-a-service and simultaneously producing verifiably random sequences of numbers are described. When distributing quantum entanglement between customers Alice and Bob, Alice and Bob may exchange information pertaining to a measurement basis that they respectively used when performing measurements using respective halves of entangled particles. When customer Alice, for example, determines that both Alice and Bob have performed a given measurement in a same measurement basis, said result may be used in a quantum key distribution (QKD) code. When customer Alice determines that they have not performed the given measurement in the same measurement basis, Alice may concatenate said portion of the results into a private and verifiable sequence of random numbers. Providing distributed quantum entanglement therefore results in both a QKD code between said customers and in respective private and verifiably random sequences of numbers.

Abstract: An aerial vehicle is configured to operate within indoor spaces. The aerial vehicle is programmed with positions of waypoints within three-dimensional space, and to calculate a trajectory for traveling through such waypoints in a manner that minimizes snap of the aerial vehicle. Where a distance between a pair of the waypoints is sufficiently long, the aerial vehicle inserts intervening waypoints for planning purposes, and programs the aerial vehicle to travel at a maximum speed between the intervening waypoints. Upon detecting an obstacle with a first range using one or more sensors, the aerial vehicle reduces its speed and monitors a second, shorter range using the sensors, and compensates for motion between such readings.

Abstract: A storage application may provide protection of data accesses by clients without incurring metadata storage costs. A request to store a record may be received, where subsequent accesses to the stored data are protected by an access condition that includes a key or other metadata. To store the record, a composite record including the record and the security key may be generated and a detection code may be determined for the composite record. The record may then be stored along with the detection code. A request to access the record may then be received, the access request including an access key. The record and detection code may be retrieved and a new composite record including the retrieved record and the access key may be generated. Satisfaction of the access condition may be determined according to a new detection code generated from the new composite record.

Abstract: Systems, devices, and methods are provided for determining factually consistent generative narrations. A narrative may be generated by performing steps to determine one or more metadata messages for a first portion of a video stream, determine transcribed commentary for a second portion of the video stream, wherein the second portion includes the first portion, and determine a prompt based at least in part on the one or more metadata messages and the transcribed commentary. The prompt may be provided to a generative model that produces an output text. Techniques for performing a factual consistency evaluation may be used to determine a consistency score for the output text that indicates whether the output text is factually consistent with the one or more metadata messages and the transcribed commentary. A narrated highlight video may be generated using the consistent narrative.

The radio-based network includes a radio access network and an associated core network. A request is received from the organization to configure one or more parameters affecting primary keys in the associated core network. The primary keys correspond to pre-shared keys of client devices permitted to access the radio-based network. Storage of the primary keys is customized in the associated core network based at least in part on the one or more parameters in response to the request.

Abstract: Implementations for compositing two input signals to form a higher quality signal are described. A first input signal is received from a first input device and a second input signal is received from a second input device. The first input signal and the second input signal are combined into a composite input signal. It is then determined that the composite input signal has a higher quality than either the first input signal or the second input signal individually. Based on that determination, the composite input signal is selected for use by the media conferencing service as part of a media conference.
