Abstract: The present disclosure relates to systems, methods, and computer-readable media for identifying a variety of events that occur within a gaming session and generating event reports based on the identified events. For example, a gaming service (e.g., a cloud gaming server) can leverage content analysis and event recognizer services on a cloud computing system to detect one or more in-game events based on gaming content (e.g., video content, audio content, controller inputs) that is delivered to a client system. Systems described herein can train and implement event recognizers trained to track various in-game events across multiple gaming applications. Based on the tracked events, the systems described herein can generate event reports for events, individual users, and groups of users of the cloud computing system.

Abstract: Automatically selecting an encrypted network connection (such as a VPN tunnel) to use when communicating through another encrypted connection node with which there are multiple encrypted network connections with the computing system. The selection is based predicted latency of that encrypted network connection. The prediction is based on round-trip times of communications over the respective encrypted network connection. This is quite difficult since the encrypted network connection itself is not the entire path of the outgoing message and corresponding incoming message.

Abstract: Technologies are described for categorization of time blocks in calendars. A time block to be categorized on a user's calendar may be determined based on a direct user input or inference from user history or behavior. Next, a category to be assigned, a beginning, and an end for the time block may be determined. The time block may be the same on all work days, different on each day, etc. One or more exceptions to be processed during the categorized time block may also be determined through direct user input or inference. Then, one or more rules associated with the assigned category restricting scheduling of events on the user's calendar during the categorized time block may be implemented subject to the one or more exceptions.

Abstract: Innovations in control and use of chroma quantization parameter (“QP”) values that depend on luma QP values. More generally, the innovations relate to control and use of QP values for a secondary color component that depend on QP values for a primary color component. For example, during encoding, an encoder determines a QP index from a primary component QP and secondary component QP offset. The encoder maps the QP index to a secondary component QP, which has an extended range. The encoder outputs at least part of a bitstream including the encoded content. A corresponding decoder receives at least part of a bitstream including encoded content. During decoding, the decoder determines a QP index from a primary component QP and secondary component QP offset, then maps the QP index to a secondary component QP, which has an extended range.

In one exemplary embodiment disclosed herein, a reference frame comprising a group of blocks is processed, and motion information for the group of blocks is compressed at least by buffering representative motion-vector information and representative reference-frame index information for the group of blocks. The representative reference-frame index information comprises reference-frame index information of a representative block of the group of blocks, and the representative reference-frame index information represents reference-frame index information for the group of blocks during processing of a current frame.

Abstract: A strain sensor that has an associated temperature compensation circuit. The strain sensor is temperature-compensated as it has a temperature compensation circuit that, when powered, applies an applied voltage across the applied voltage terminals of the strain sensor that has a compensating temperature dependency. That is, the applied voltage has a temperature dependency of one polarity that is opposite a temperature dependency of the strain sensor. Because of this temperature compensation, the signal representing strain has a more stable scale factor between the endured strain and the signal representing the strain. Thus, the accuracy of the strain sensor is improved.

Abstract: A method of probabilistically canceling noise in a measurement-based quantum device includes obtaining a sequence of ideal measurements included within a quantum algorithm and selecting a sequence of noisy measurements for emulating the sequence of ideal measurements. Each of the noisy measurements in the selected sequence approximates a corresponding one of the ideal measurements and is adjusted by a quantum correction, where the noisy measurements are selected according to a carefully chosen distribution to cancel known features of noise in those same noisy measurements in the sequence.

Abstract: A computer system identifies an event from a management system log associated with a first container host. The presence of the event in the management system log is indicative that the first container host identified a fatal system error at the first container host. Based on the event, the computer system determines that a first instance of a container that is provisioned at the first container host has been isolated to the first container host. Based on the first instance of the container having been isolated to the first container host, the computer system instructs a second container host to provision a second instance of the container at the second container host.

Abstract: A secure inference over Deep Neural Networks (DNNs) using secure two-party computation to perform privacy-preserving machine learning. The secure inference uses a particular type of comparison that can be used as a building block for various layers in the DNN including, for example, ReLU activations and divisions. The comparison securely computes a Boolean share of a bit representing whether input value x is less than input value y, where x is held by a user of the DNN, and where y is held by a provider of the DNN. Each party computing system parses their input into leaf strings of multiple bits. This is much more efficient than if the leaf strings were individual bits. Accordingly, the secure inference described herein is more readily adapted for using in complex DNNs.

Abstract: Improved video compression and video streaming systems and methods are disclosed for environments where camera motion is common, such as cameras incorporated into head-mounted displays. This is accomplished by combining a 3D representation of the shape of the user's environment (walls, floor, ceiling, furniture, etc.), image data, and data representative of changes in the location and orientation (pose) of the camera between successive image frames, thereby reducing data bandwidth needed to send streaming video in the presence of camera motion.

Abstract: Techniques and algorithms for monitoring network congestion and for triggering a flow to follow a new path through a network. The network is monitored, and network feedback data is acquired, where that data indicates whether the network is congested. If the network is congested, a feedback-driven algorithm can trigger a flow to follow a new path. By triggering the flow to follow the new path, congestion in the network is reduced. To identify congestion, the feedback data is analyzed to determine whether flows are colliding. The feedback-driven algorithm determines that a network remapping event is to occur in an attempt to alleviate the congestion. A flow is then selected to be remapped to alleviate the congestion.

Abstract: A video indexing system generates descriptive metadata for a video including identifiers for each of multiple detections that each correspond to a select one of multiple subjects that appear in the video. These detections are used to create relational graph data for the video, where the relational graph data includes nodes corresponding to each of the multiple subjects that appear in the video. A knowledge graph is queried with unique identifiers corresponding to the multiple subjects of the video to retrieve implicit relational data for each of the multiple subjects, and a merged relational graph is created by merging the implicit relational data retrieved from the knowledge graph with the relational graph data created for the video. A search engine uses the merged relational graph to identify video content relevant to a user query that is based on an implicit relation. Search results identifying the relevant content are presented on a user device.
