    摘要： Architecture that scales up the non-negative matrix factorization (NMF) technique to a distributed NMF (denoted DNMF) to handle large matrices, for example, on a web scale that can include millions and billions of data points. To analyze web-scale data, DNMF is applied through parallelism on distributed computer clusters, for example, with thousands of machines. In order to maximize the parallelism and data locality, matrices are partitioned in the short dimension. The probabilistic DNMF can employ not only Gaussian and Poisson NMF techniques, but also exponential NMF for modeling web dyadic data (e.g., dwell time of a user on browsed web pages).

    摘要翻译： 将非负矩阵分解（NMF）技术扩展到分布式NMF（表示为DNMF）以处理大型矩阵的架构，例如，可以包括数百万和数十亿个数据点的网络规模。 为了分析网络规模数据，DNMF通过并行性应用于分布式计算机集群，例如数千台机器。 为了最大化并行度和数据局部性，矩阵在短维中被划分。 概率DNMF不仅可以采用高斯和泊松NMF技术，还可以采用指数NMF来建模网络二进制数据（例如，用户在浏览的网页上的停留时间）。

    摘要： A communication system, method, computer program product, and apparatus include common equipment shared between multiple independently administered networks. The common equipment is reconfigurable and expandable and provides changed communication capacity and functions when additional elements are added or reconfigured. Configurable features include, for example, communication bandwidth, Quality of Service, and a number of communication satellites included in the communication system. The common equipment includes expandable elements including, for example, a single hub modem chassis that can expand to communicate with more than one communication satellite and a protocol processor that can share a protocol processing task with another protocol processors.

    摘要： A system is described herein that includes a preference deriver component that receives a predefined preference rule that indicates a hierarchy pertaining to entities belonging to a domain, wherein each of the entities has attributes and values for such attributes corresponding thereto, and wherein the preference deriver component outputs preferences between various subsets of entities based at least in part upon the preference rule. The system also includes a learning component that learns a computer-implemented ranker component that is configured to rank the entities belonging to the domain, wherein the learning component learns the computer-implemented ranker based at least in part upon the preferences between the various subsets of the entities output by the preference deriver component.

    摘要： Technologies pertaining to fact lookup queries are described herein. A relational database is automatically built by extracting attribute identities and attribute values from a one dimensional table, wherein the one dimensional table does not include an entity identity that corresponds to the attribute identity and the attribute value. The entity identity is inferred, and the attribute value is indexed in a relational database by the entity identity and the attribute identity. When a query is issued by a user that includes the entity identity and the attribute identity, the corresponding attribute value in the relational database is returned to the user.

    摘要： A display method based on Vchip includes: displaying a plurality of first ratings in a first level menu; and displaying a plurality of second ratings corresponding to each of the first ratings in a second level menu. In one embodiment, the first ratings are program content ratings, and the second ratings are age ratings. In other embodiment, the first ratings are age ratings, and the second ratings are program content ratings. The program content rating and the corresponding age ratings are respectively displayed in two level menus; therefore, it is easy to be understood and does not make the users confused, and is more convenient for operation.
