  • Patent number: 9563674
    Abstract: A data exploration user interface includes a selection area with selectable representations of queryable fields of a data source and a visualization area where query results are displayed as data visualizations. Queries are generated by dragging fields from the selectable area to the visualization area of the user interface. A tree structure of data visualizations may be created by dragging data points out of a displayed visualization and applying additional fields to create a new query and resulting visualization. The tree structure is graphically represented with path indicators that provide historical context for each new data visualization within the visualization are of the user interface.

  • Patent number: 9459947
    Abstract: Techniques for error report processing are described herein. Error reports, received by a developer due to program crashes, may be organized into a plurality of “buckets.” The buckets may be based in part on a name and a version of the application associated with a crash. Additionally, a call stack of the computer on which the crash occurred may be associated with each error report. The error reports may be “re-bucketed” into meta-buckets to provide additional information to programmers working to resolve software errors. The re-bucketing may be based in part on measuring similarity of call stacks of a plurality of error reports. The similarity of two call stacks—a measure of likelihood that two error reports were caused by a same error—may be based in part on functions in common, a distance of those functions from the crash point, and an offset distance between the common functions.

  • Publication number: 20160239550
    Abstract: A system for frequent pattern mining uses two layers of processing: a plurality of computing nodes, and a plurality of processors within each computing node. Within each computing node, the data set against which the frequent pattern mining is to be performed is stored in shared memory, accessible concurrently by each of the processors. The search space is partitioned among the computing nodes, and sub-partitioned among the processors of each computing node. If a processor completes its sub-partition, it requests another sub-partition. The partitioning and sub-partitioning may be performed dynamically, and adjusted in real time.

  • Publication number: 20160140208
    Abstract: In some examples, a time-series data set can be analyzed and grouped in a fast and efficient manner. For instance, fast grouping of multiple time-series into clusters can be implemented through data reduction, determining cluster population, and fast matching by locality sensitive hashing. In some situations, a user can select a level of granularity for grouping time-series into clusters, which can involve trade-offs between the number of clusters and the maximum distance between two time-series in a cluster.

  • Publication number: 20160117373
    Abstract: The techniques described herein provide tools that summarize a dataset by creating a final set of segments that, when visually presented via a histogram or other data presentation tool, show the distribution of at least a portion of the data. To create the final set of segments, the techniques described herein may collect or receive a dataset with distinct values, and divide the dataset into a number of segments that is less than or equal to a segment presentation threshold (e.g., ten segments). After creating the final set of segments, the techniques may configure and/or present data visualizations, such as histograms, for the created segments so that an observer is provided with a good viewing experience.

  • Patent number: 9301147
    Abstract: A method and an apparatus for protecting data carried on an Un interface between a eNB and a relay node are disclosed. Three types of radio bearers (RBs) are defined over the Un interface: signaling radio bearers (SRBs) for carrying control plane signaling data, signaling-data radio bearers (s-DRBs) for carrying control plane signaling date; and data-data radio bearers (d-DRBs) for carrying user plane data. An integrity protection algorithm and an encryption algorithm are negotiated for control plane signaling data on an SRB, control plane signaling data carried on an s-DRB, and user plane data carried on a d-DRB. With the respective integrity protection algorithm and encryption algorithm, the data over the Un interface can be protected respectively. Therefore, the security protection on the Un interface is more comprehensive, and the security protection requirements of data borne over different RBs can be met.
