Abstract: A system and method for automatically scaling consumer servers in a data processing system. To build an automatic scaling system, the present disclosure allows consumers to obtain additional information, e.g., the number of events that await to be read from an aggregator when receiving an event from the aggregator. This additionally obtained number provides a direct gauge for the data processing system to determine when the consumers are over-provisioned, i.e., when the number of events left to be read is close to zero, as well as when the consumers are under-provisioned, e.g., when the number of events left to be read continues to increase. As a result, the consumers can be automatically scaled to handle the dynamic data processing demand while providing optimal resource allocation.

Abstract: Innovations in phase quantization during speech encoding and phase reconstruction during speech decoding are described. For example, to encode a set of phase values, a speech encoder omits higher-frequency phase values and/or represents at least some of the phase values as a weighted sum of basis functions. Or, as another example, to decode a set of phase values, a speech decoder reconstructs at least some of the phase values using a weighted sum of basis functions and/or reconstructs lower-frequency phase values then uses at least some of the lower-frequency phase values to synthesize higher-frequency phase values. In many cases, the innovations improve the performance of a speech codec in low bitrate scenarios, even when encoded data is delivered over a network that suffers from insufficient bandwidth or transmission quality problems.

A sensor on the secondary computing device determines that the secondary computing device has a first tilt position that is associated with a non-sharing mode.

The sensor senses that the secondary computing device has reached the second tilt position and shares the entire content item with the primary computing device.

Abstract: A dynamic peak power management system may prevent brownouts while improving performance and user experience compared to conventional techniques. A current threshold may be set below the maximum current capability (Imax) of a battery. If the current drawn from the battery exceeds the current threshold repeatedly, then system components may be throttled to decrease their peak power usage. If the current drawn from the battery stays below the current threshold for some time, then system components may be unthrottled to improve performance. This dynamic adaptable technique for managing peak power does not unnecessarily sacrifice performance by preemptively throttling system components to avoid the rare worst-case scenario where power spikes of system components perfectly align in time.

Abstract: A training process produces a machine-learned model that, once trained, can be applied to process different types of data items. The training process accomplishes this result by combining data items in a training set with type-specific parameter information, to produce supplemented data items. The training process then trains a model based on the supplemented data items. Training involves adjusting model weights together with the type-specific parameter information. In an inference stage of processing, the technology combines a new data item with an appropriate type of trained parameter information, and then maps the resultant supplemented data item to an output data item. The technology is particularly effective in adapting an initial model to a new subject matter domain in those situations in which a robust set of data items that pertain to the subject matter domain and which have a desired type is lacking.

Abstract: Methods for intelligent automatic merging of source control queue items are performed by systems and apparatuses. Project changes are submitted in build requests to a gated check-in build queue requiring successful builds to commit changes to a code repository according to source control. Multiple pending build requests in the build queue are intelligently and automatically merged into a single, pending merged request based on risk factor values associated with the build requests. For merged requests successfully built, files in the build requests are committed and the build requests are removed from the queue. Merged requests unsuccessfully built are divided into equal subsets based on updated risk factor values using information from the unsuccessful build. Successful builds of subsets allow for committing of files and removal from the build queue, while unsuccessful builds are further divided and processed until single build requests are processed to identify root cause errors.
