Abstract: During a throttling parameter determination, a throttling manager of a file storage service transmits a maximum throughput allotment to an access node of the service. The allotment is based at least in part on the estimated size of a file system instance. The access node assigns respective portions of the allotment to individual ones of a set of persistent client connections classified as sustainable-demand connections, such that the connections are able to sustain their throughputs for a time period. The remainder of the allotment is distributed among one or more high-demand persistent client connections. The access node enforces the throughput limits assigned to the connections.

Abstract: This disclosure is directed to an automated unmanned aerial vehicle (“UAV”) self-identification system, devices, and techniques pertaining to the automated identification of individual UAVs operating within an airspace via a mesh communication network, individual UAVs and a central authority representing nodes of the mesh network. The system may detect nearby UAVs present within a UAV's airspace. Nearby UAVs may self-identify or be identified via correlation with one or more features detected by the UAV. The UAV may validate identifying information using a dynamic validation policy. Data collected by the UAV may be stored in a local mesh database and distributed to individual nodes of the mesh network and merged into a common central mesh database for distribution to individual nodes of the mesh network. UAVs on the mesh network utilize local and central mesh database information for self-identification and to maintain a dynamic flight plan.

Abstract: A machine learning engine may correlate contextual information associated with a misspelling in a publication with a likelihood that the misspelling is intentional in nature. Training data may be generated by analyzing one or more past publication to identify misspellings and labeling the misspellings as intentional. A contextual indicators application may analyze the context in which intentional misspellings have been previously included within publication to identify indicators of future misspellings being intentional. A machine learning engine may use the training data and indicators to generate an intentional linguistic deviation (ILD) prediction model to determine whether a new misspelling is an intentional misspelling. The machine learning engine may also determine weights for individual indicators that may calibrate the influence of the respective individual indicators.

Abstract: A programmatic interface is implemented, enabling a client of a stream management service to select a data ingestion policy for a data stream. A client request selecting an at-least-once ingestion policy is received. In accordance with the at-least-once policy, a client may transmit an indication of a data record one or more times to the service until a positive acknowledgement is received. In response to receiving a plurality of transmissions indicating a particular data record, respective positive acknowledgements are sent to the client. Based on a persistence policy selected for the stream, copies of the data record are stored at one or more storage locations in response to one particular transmission of the plurality of transmissions.

Abstract: Technologies are described herein for reducing network traffic when replicating memory data across hosts. The memory data stored in a main memory of the host computer is replicated to a main memory of a second host computer. Memory data from the local data storage of the second host computer that is a duplicate of memory data from the main memory is identified. Instead of sending the memory data from the main memory that is duplicated, the duplicated memory is copied from the local storage to the main memory of the second host computer.

Abstract: Various embodiments of a method and system for capturing and utilizing item attributes are described. Various embodiments may include a mobile image capture apparatus, which may include a computer system configured to execute an image capture application. The image capture application may instruct an agent to capture an image of an item label. A data extraction component may be configured to process the images captured by the mobile image capture apparatus. For a given captured image, the data extraction component may in various embodiments be configured to perform OCR to determine one or more strings of characters from the image. The data extraction component may be further configured to determine whether one or more patterns match a determined string of characters. In response to the detection of a particular pattern matching a particular string of characters, the data extraction component may extract and store an attribute of the corresponding item.

Abstract: Features are disclosed for spotting keywords in utterance audio data without requiring the entire utterance to first be processed. Likelihoods that a portion of the utterance audio data corresponds to the keyword may be compared to likelihoods that the portion corresponds to background audio (e.g., general speech and/or non-speech sounds). The difference in the likelihoods may be determined, and keyword may be triggered when the difference exceeds a threshold, or shortly thereafter. Traceback information and other data may be stored during the process so that a second speech processing pass may be performed. For efficient management of system memory, traceback information may only be stored for those frames that may encompass a keyword; the traceback information for older frames may be overwritten by traceback information for newer frames.
