  • Patent number: 10785182
    Abstract: Large batches of social media communications may be automatically annotated. This provides techniques to create large labeled datasets without the assistance of human labelers. For instance, social media communications may be fetched and annotated as actionable or noise for a given account (e.g., a brand handle on Twitter®) without human review. Social media communications from users who are attempting to engage with a brand or entity on a social media platform may be annotated as actionable, whereas other communications may be labeled as noise.

  • Patent number: 10783044
    Abstract: A method and apparatus for a mechanism of disaster recovery and instance refresh in an event recordation system are described. A first request for events associated with a first topic is received. A first set of events associated with the first topic are retrieved from a primary event recordation system. Each event from the first set of events includes a first commit identifier indicating the order with which each event is stored in the primary event recordation system. For each event from the first set of events a first replay identifier is determined based on the first commit identifier and a first value of a low commit identifier. The first replay identifier is exposed to event consumers for identifying the event. In response to the first request each event from the first set of events is transmitted with the replay identifier.

  • Patent number: 10742535
    Abstract: A method and system or monitoring a resource consumption of an application running on a computer. A first metric describes the resource consumption of the application as a first function of time. A wavelet analysis of the first function of time is performed. A discontinuity in the first function is detected at a first time at which a coefficient determined from the wavelet analysis exceeds a specified threshold. A cross-correlation of the first metric and a second metric describing the resource consumption of the application as a second function of time are calculated. A diagnostic level associated with the discontinuity in the first function is adjusted based on the calculated cross-correlation. In response to adjusting the diagnostic level, a debugging function on the application is started in response to the cross correlation having a value indicative of an anomaly within the application.

  • Patent number: 10685113
    Abstract: In some implementations, a computing device can determine the similarity of binary executables. For example, the computing device can receive an application, including a binary executable. The computing device can generate function signatures for the functions called within the binary executable. The computing device can generate a locality sensitive hash value for the application based on the function signatures. The computing device can group applications based on the locality sensitive hash value generated for each application. The computing device can compare the function signatures of the binary executables of the applications within a group to determine the similarity of the applications. If two applications have binary executables that are over a threshold percentage of similarity, the two applications can be identified as clones of each other.

  • Patent number: 10685652
    Abstract: This disclosure describes, in part, techniques for determining device groupings, or clusters, for multiple voice-enabled devices. The device clusters may be determined based on metadata data for audio signals (or audio data) generated by each of the multiple voice-enabled devices. For example, a remote system may analyze timestamp data for the audio signals received from the devices, and determine that the devices detected the same voice command of a user based on the timestamp data indicating that the audio signals were received within a threshold period of time from each other. Additionally, the remote system may analyze other metadata of the audio data, such as signal-to-noise (SNR) values, and determine that the SNR values are within a threshold value. The remote system may determine device clusters for the voice-enabled devices of a user based on these, and potentially other, types of metadata of the audio signals.

    Abstract: Some embodiments of the invention provide a novel architecture for debugging devices. This architecture includes numerous devices that without user intervention automatically detect and report bug events to a set of servers that aggregate and process the bug events. When a device detects a potential bug event, the device in some embodiments generates a description of the potential bug event, and sends the generated description to the server set through a network. In addition to generating such a description, the device in some embodiments directs one or more of its modules to gather and store a collection of one or more data sets that are relevant to the potential bug event, in case the event has to be further analyzed by the server set. In the discussion below, the generated bug-event description is referred to as the event signature, while the gathered collection of data sets for an event is referred to as the event's data archive.

  • Patent number: 10223175
    Abstract: A method, system, and/or computer program product modify a hardware device based on a time series of data. One or more processors standardize a time series of data received from sensors that are monitoring a hardware device. The processor(s) determine a time delta that measures how long a disruption in the time series lingers after an event that is detected by the sensors, and use the time delta to establish time ranges before, during and after each event. The processor(s) determine which events represented by the time series of data are significant, and then reduce a number of significant events described by the time series of data to a predefined level by removing events that have tags not found associated with other events in the time series of data to generate a modified time series of data, which is used to modify the hardware device.

  • Patent number: 10204698
    Abstract: An error injection system of a built-in self-repairable memory system renders the redundant spare columns of the repairable memory accessible to built-in self-test (BIST) read and write operations. To this end, the error injection system selectively injects fault data at one or more locations of the main memory during a BIST sequence, causing the BIST controller to issue a repair instruction that allocates one or more spare columns as replacement memory areas for the presumed faulty main memory locations. Thereafter, BIST read/write operations directed to the main memory locations will be performed on the allocated spare columns, thereby allowing the spare columns to be validated as part of the BIST. Injection of fault data to the main memory locations in this manner can also facilitate validation of the built-in self-repair logic by verifying the repair instruction codes that are generated in response to the injected faults.
