摘要： Source code is generated that includes one or more iterator-based expressions such as declarative queries. The source code is translated into an intermediate language that classifies operators making up the iterator-based expressions into classes based on whether the operators are aggregating, element-wise, or sink operators. The intermediate language, including the identified classes, is processed using an automaton to replace the iterator-based expressions with one or more equivalent non-iterator-based expressions. Where an iterator-based expression is nested, the nested expression is processed using an equivalent number of nested automatons. The resulting optimized source code may be compiled and executed using fewer virtual function calls than the equivalent non-optimized source code.
摘要翻译：生成包含一个或多个基于迭代器的表达式（如声明性查询）的源代码。源代码被翻译成一种中间语言，它将运算符组成基于迭代器的表达式分类为基于运算符是聚合的，元素的还是汇点运算符的类。使用自动机处理包括所识别的类的中间语言，以使用一个或多个等价的基于非迭代器的表达式来替换基于迭代器的表达式。在嵌套基于迭代器的表达式的情况下，使用等效数量的嵌套自动机来处理嵌套表达式。所得到的优化源代码可以使用比等效的非优化源代码更少的虚拟函数调用来编译和执行。

摘要： Caching is provided to speed up the recomputation of an application, function, or other computation that relies on a very large input dataset, when the input dataset is changed. Previous computation results are stored in storage, for example, in a system-wide, global, persistent cache server. The storage enables the reuse of previous results on the parts of the dataset that are old and unchanged, and to only run the computation on the parts of the dataset that are new or changed. The application then combines the results of the two parts to form the final result.
摘要翻译：提供缓存，以便在输入数据集更改时，加速重新计算依赖于非常大的输入数据集的应用程序，函数或其他计算。以前的计算结果存储在存储器中，例如，在全系统的全局，持久缓存服务器中。该存储可以使旧数据集的旧且不变的部分重新使用以前的结果，并且仅在新数据集或更改的数据集的部分上运行计算。然后，应用程序将两部分的结果相结合，形成最终结果。

摘要： General-purpose distributed data-parallel computing using a high-level language is disclosed. Data parallel portions of a sequential program that is written by a developer in a high-level language are automatically translated into a distributed execution plan. The distributed execution plan is then executed on large compute clusters. Thus, the developer is allowed to write the program using familiar programming constructs in the high level language. Moreover, developers without experience with distributed compute systems are able to take advantage of such systems.

摘要： Methods for generating and displaying images associated with one or more virtual objects within an augmented reality environment at a frame rate that is greater than a rendering frame rate are described. The rendering frame rate may correspond with the minimum time to render images associated with a pose of a head-mounted display device (HMD). In some embodiments, the HMD may determine a predicted pose associated with a future position and orientation of the HMD, generate a pre-rendered image based on the predicted pose, determine an updated pose associated with the HMD subsequent to generating the pre-rendered image, generate an updated image based on the updated pose and the pre-rendered image, and display the updated image on the HMD. The updated image may be generated via a homographic transformation and/or a pixel offset adjustment of the pre-rendered image.

摘要： Techniques for defocusing queries over big datasets and dynamic datasets are provided to broaden search results and incorporate all potentially relevant data and avoid overly narrowing queries. An analytic component can receive queries directed at one region of a dataset and analyze the queries to generate inferences about the queries. The queries can then be defocused by a defocusing component and incorporate a larger dataset than originally searched to broaden the queries. The larger dataset can incorporate all, or a part of the original dataset and can also be disparate from the original dataset. Clusters of queries can also be merged and unified to deal with ‘local minima’ issues and broaden the understanding of the dataset. In other embodiments, dynamic data can be monitored and changes tracked, to ensure that all portions of the dataset are being searched by the queries.

摘要： The subject disclosure relates to using structured query language constructs in non-structured query language domains. For example, through mathematical and logical transformation of concepts from a key, value pair domain associated with structured query language data structures to graphical-related data structures, the value originating in the structured query language domain can be modified for use in non-structured query language domains. This can open up options in analytics and can solve some of the problems associated with liner algebra.

摘要： A system for providing augmented reality detects foreground occluders in an image of a video stream. One or more virtual objects are then rendered appropriately with respect to the occluders. Location information associated with the image is used to retrieve a three dimensional representation of the location where the image was taken. Features that are expected to appear in the image based on the three dimensional location but that cannot be located are used to determine regions of the image that are likely to include foreground occluders. Pixels in these regions are used to train a color model that classifies pixels as either part of the background of the image or part of one or more foreground occluders. The pixels in the image are classified using the model, and one or more virtual objects are rendered so that they appear behind any foreground occluders.

摘要： The embodiments contemplate a system and method for obtaining related results for a portion of a query and for generating an updated set of queries for a cache of a server. Other queries beginning with the portion of the query may be identified and obtained from a data structure that includes a server cache and a set of common queries. Once the other queries are identified, results for the other queries are obtained from the server cache or from a back-end database. A set of common queries, which may include deleted and additional queries, may be utilized to generate the updated set of queries for the server. Both missing queries and deleted queries that may belong to the server based on an assignment function are inserted into a queue, which is later delivered to the cache of the server. The transfer may occur during a low-activity or idle state.
