LINQtoDataSet 也可用于查询从一个或多个数据源合并的数据。 LINQ to DataSet can also be used to query over data that has been consolidated from one or more data sources. 与DataReader不同的是,DataSet 能传递给远程客户端。 Unlike the DataReader, the DataSet can be passed to a remote client. Dataset 的特征元素被构成了形如(batch_size,num_features)的数组。The features element of the Dataset are now arrays with shape(batch_size, num_features).HarvardLibraryBibliographicDataset 包含哈佛大学73个图书馆的1200万条开放访问的目录记录。 The dataset contains 12 million open-access catalog records from Harvard's 73 libraries. 如果在应用程序设计时已知DataSet 的架构,则建议使用类型化DataSet。 If the schema of the DataSet is known at application design time, a typed DataSet is recommended. 大型企业的DataSet 与互联网公共数据结合会是训练企业级“大脑”的方向。 The combination of DataSet and Internet public data of large enterprises is the direction of training enterprise class“brain”. 最后,DataAdapter提供连接DataSet 对象和数据源的桥梁。 Finally, the DataAdapter provides the bridge between the DataSet object and the data source. SparkRDD[T],ResilientDistributedDataset (弹性分布式数据集),像是它顶层抽象的集合。 Spark RDD[T], Resilient Distributed Dataset , looks like a collection at the top level of its abstraction. (2)DataSet API中的有状态操作使用简化的in-memory/out-of-core数据结构,而不是键/值索引。 Stateful operation in the DataSet API use simplified in-memory/out-of-core data structures, rather than key/value indexes. 著名的新闻数据集(20newsgroupsdataset )是一个标尺,在多篇文章中被用来比较不同的模型。 The famous 20 newsgroups dataset is a benchmark in the field, and has been used to compare different models in several papers. Fill方法使用DataSet 的现有架构,并使用从SelectCommand返回的数据填充它。 Fill method uses the existing schema of the DataSet and populates it with data returned from the SelectCommand. Flink程序的基本构建块是streams和transformations(注意,DataSet 在内部也是一个stream)。 The basic building blocks of Flink programs are streams and transformations(note that a DataSet is internally also a stream). NET在DataSet 中提供了广泛的XML集成,并公开了SQLServer2000及其更高版本提供的部分XML功能。 NET provides extensive XML integration in the DataSet , and also exposes some of the XML functionality provided by SQL Server 2000 and later. Org标准来描述他们的数据集,用户在Dataset Search中找到的数据集的种类和覆盖范围将会越来越多。 Org standard to describe their datasets, the variety and coverage of datasets that users will find in Dataset Search, will continue to grow. YelpAcademicDataset :30家大学的250个最接近商业的所有数据和评论,为学生和学者来探讨和研究. Yelp Academic Dataset , all the data and reviews of the 250 closest businesses for 30 universities for students and academics to explore and research. 虽然这样做确实能提高性能,但是,当对DataSet 中的数据更新进行管理时,可能会增加应用程序的复杂性。 Though this does improve performance, it may increase the complexity of your application when managing updates to data in the DataSet . 使用RDD的用户会发现Dataset API非常熟悉,因为它提供了许多相同的功能转换(例如map,flatMap,filter)。 Users of RDDs will find the Dataset API quite familiar, as it provides many of the same functional transformations(e.g. map, flatMap, filter). LINQtoDataSet 使您可以通过使用为其他数据源提供的相同查询功能,在DataSet 中加入更丰富的查询功能。 LINQ to DataSet enables you to build richer query capabilities into DataSet by using the same query functionality that is available for other data sources. 此外,它说明了如何使用DataSet 和DataReader对象来支持Web窗体的本地数据存储要求和数据处理要求。 In addition, it explains how to use the DataSet and DataReader objects to support the local data storage and data manipulation requirements of Web Forms. 因此,DataSet 为自动增量值生成负数,与数据源生成的正自动增量值不冲突。 As a result, the DataSet generates negative numbers for auto-incremented values that do not conflict with the positive auto-increment values generated by the data source. 波士顿房价数据集(BostonHousePriceDataset )包含对房价的预测,以千美元计,给定的条件是房屋及其相邻房屋的详细信息。 The Boston House Price Dataset involves the prediction of a house price in thousands of dollars given details of the house and its neighborhood. 使用LINQtoDataSet 来表述查询类似于对其他启用LINQ的数据源使用Language-IntegratedQuery(LINQ)。 Formulating queries using LINQ to DataSet is similar to using Language-Integrated Query(LINQ) against other LINQ-enabled data sources. 案列链接simpleexampleonthisdataset 举例说明了如何从原始问题出发,形成用于scikit-learning中的数据。 The simple example on this dataset illustrates how starting from the original problem one can shape the data for consumption in scikit-learn. Python不支持Dataset API,但由于Python的动态特性,可以使用Dataset API的许多好处,R也如此。 The Dataset API is not supported by Python, but, because of the dynamic nature of Python, many benefits of the Dataset API are available.
