摘要： Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for training a heterogenous graph neural network (GNN) to generate user embeddings corresponding to users and item embeddings corresponding to items. An example embodiment generates a first user interaction graph for a first time window and a second user interaction graph for a second time window, wherein each graph represents users and items as nodes and user-item interactions within the respective time window as edges, samples user-item node pairs from the second user interaction graph, and trains the heterogeneous GNN based on user-item node pairs from the first user interaction graph that correspond to the sampled user-item node pairs from the second user interaction graph. User and item embeddings generated by the trained GNN may be used to determine a relevancy of a given item with respect to a given user.

摘要： Disclosed herein are system, apparatus, article of manufacture, computer-implemented method, and/or computer-program product (computer-readable non-transitory storage medium) embodiments, and/or combinations and sub-combinations thereof, for an environmentally aware remote control. An example embodiment operates by at least one processor detecting a first signal and a second signal and receiving information corresponding to at least a physical position where a user is located relative to at least the first physical source. The at least one processor may further operate by calculating a time difference between a given sample of the first signal and a corresponding sample of a second signal at the physical position where the user is located, and adjusting a relative timing of the first signal with respect to the second signal. In some further embodiments, the at least one processor may adjust other attributes of either signal besides timing, e.g., audio characteristics such as volume, pitch, other filtering, etc.

摘要： In one aspect, a method includes using a Wi-Fi module of a computing device to detect that an end-user has exited a monitored environment of the computing device, where the monitored environment comprises an Internet of Things (IoT) device communicatively coupled to the computing device over an IoT network. The method also involves in response to detecting that the end-user has exited the monitored environment, triggering a first IoT action at the IoT device. The method also involves after detecting that the end-user has exited the monitored environment and triggering the first IoT action, using the Wi-Fi module of the computing device to detect that the end-user has reentered the monitored environment. The method also involves in response to detecting that the end-user has reentered the monitored environment, triggering a second IoT action at the IoT device.

摘要： Disclosed herein are various embodiments, for a fast boot system. An example embodiment operates by determining that one or more programs have been loaded into memory on a boot-up of a device. A snapshot of the memory including the loaded one or more programs is captured. Operations of the device are monitored after the snapshot has been captured. It is determined that a first program of the one or more programs was updated during the monitoring. A restart of the device is detected, wherein the snapshot is loaded into the memory in lieu of loading the one or more programs, and wherein the first program is updated during the restart of the device.

摘要： In a communication system where a channel teed carrying a media stream is broadcast for delivery of the media stream to a media client, where the channel feed further includes metadata in-band and correlated with a content frame of the media stream, but where the metadata gets removed from the channel feed before the media stream reaches the media client, a computing system (i) extracts the metadata from the channel feed and (ii) transmits out-of-band to the media client the extracted metadata in correlation with reference fingerprint data representing the frame of the media stream, the correlation being useable by the media client as a basis to re-correlate the metadata with the frame of the media stream, so as to enable the media client to carry out an action, such as dynamic ad insertion, based on the correlation of the metadata with the frame of the media stream.

An embodiment operates by receiving a command configured to instruct an API to render a graphics element. The embodiment further operates by generating, based on the command, a transcoded command configured to instruct the API to render a modified graphics element by applying a set of modification factors to a portion of the command. Subsequently, the embodiment operates by transmitting the transcoded command to the API.
