Abstract: A speech-based system is configured to interact with a user through speech to determine intents and goals of the user. The system may analyze multiple dialog turns in order to determine and fully define a goal that the user is trying to express. Each dialog turn comprises a user utterance. Each dialog turn may also comprise a system speech response. In order to evaluate the performance of the system, logged data is analyzed to identify goal segments within the logged data, where a goal segment is a sequence of dialog turns that relate to a corresponding user goal. A subset of the dialog turns is annotated manually to delineate goal segments. A predictive model is then constructed based on the manually annotated goal segments. The predictive model is then used to identify goal segments formed by additional dialog turns.

Abstract: A forking coordinator of a journal-based multi-data-store database determines that a forking criterion for a first journal has been met. The coordinator stores an indication that processing of transaction requests directed to a particular subset of the database is suspended. The coordinator instantiates a second journal for storing committed transaction entries for the particular subset. Metadata of the second journal indicates that transaction entries with sequence numbers in a particular range are stored in the first journal. The coordinator stores an indication that transaction processing associated with the particular subset of the system is to be resumed using the second journal.

Abstract: Methods and apparatus for handling failure of servers in traffic forwarding (TF) systems between networks. A TF system may include units each including multiple servers. Outbound and inbound traffic for a local network may be distributed among the units according to a routing technique, with each unit responsible for an allocated portion of the traffic. Servers in a unit may participate in a health check protocol to detect servers that are not healthy. If the healthy servers in a unit drops below a threshold at which the unit cannot reliably handle its allocated portion of the traffic, the servers may automatically take the unit out of service, for example by stopping advertisement of routes, and the traffic may be reallocated across the remaining units. This may help prevent congestion-related delays, high latency, packet losses, and other problems on connections through the unhealthy unit.

The items and/or images associated with color palettes may be returned based at least in part on the keyword search. Various user interfaces may be based at least in part on the keyword searching and/or trending techniques for color palettes.

Abstract: One or more grids of redundancy coded shards, such as those stored or otherwise represented on grid encoded storage systems, are combinable or extensible. For example, a generator matrix of a redundancy code may be configured so as to have a sufficient number of fields to generate a grid. The generator matrix may initially be used to generate smaller grids, which can be combined into the target grid without re-encoding most or all of the data represented thereon. In some cases, vertically derived shards of the input grids may be combined using, e.g., matrix addition, which may then be directly allocated to the target grid, while data shards and horizontally derived shards may be allocated to the target grid with no further transformation.

Abstract: An acoustic interference cancellation system that combines acoustic echo cancellation and an adaptive beamformer to cancel acoustic interference from an audio output. The system uses a fixed beamformer to generate a target signal in a look direction and an adaptive beamformer to generate noise reference signals corresponding to non-look directions. The noise reference signals are used to estimate acoustic noise using an acoustic interference canceller (AIC), while reference signals associated with loudspeakers are used to estimate an acoustic echo using a multi-channel acoustic echo canceller (MC-AEC). The system cancels the acoustic echo and the acoustic noise simultaneously by adding the estimate of the acoustic noise and the estimate of the acoustic echo to generate an interference reference signal and cancelling the interference reference signal from the target signal. The system jointly updates adaptive filters for the AIC and the MC-AEC logic to improve a robustness of the system.

Abstract: Systems and methods are disclosed which facilitate management of thin provisioned data storage. Specifically, portions of thinly provisioned data stores may be deallocated when they contain invalid data, such as data deleted by a user. A user may transmit notifications, which may include delete notifications, such as TRIM commands, to a provider of the data store (or to the data store itself) that data has been deleted. A management component may modify the data store, or metadata corresponding to the data store, to reflect the deletion. The management component may further monitor portions of the data store to determine whether individual portions contain entirely invalid data. If so, the portion may be deallocated from the thin provisioned data store, resulting in more efficient thin provisioning. Deallocation may be enabled even where deletion notifications from a user do not correspond directly to allocated storage portions.
