These are models we have decided to make. They may be a few weeks or months away from production and the pictures that you see here might not necessarily be the final versions. This is the best time to place an order with your favourite supplier to make sure he keeps the model for you...

例如,NaiveBayes实现多项式朴素贝叶斯分类器。 输出是一个NaiveBayesModel,可用于预测测试数据。NaiveBayes在本例中为Estimator。 习得的模型NaiveBayesModel可用作Transformer。 在Spark ML 中,整个机器学习过程的工作流(从获取数据、将其转换为所需格式以及将其拟合到模型)以管道形式表示。 管道由一系列PipelineStages组成...
Note(注意): 默认情况下,该操作使用 Spark 的默认并行任务数量(local model 是 2,在 cluster mode 中的数量通过 spark.default.parallelism 来确定)来做 grouping。您可以通过一个可选的 numTasks 参数来设置一个不同的 tasks(任务)数量。 reduceByKeyAndWindow(func, invFunc, windowLength, slideInterval, [...

SaveModel 分为 Append 追加、Overwrite 覆盖、ErrorIfExists 报错、Ignore 忽略四种模式,前两个比较好理解,后面两个前者代表如果地址已存在则报错,后者如果地址已存在则忽略且不影响原始数据。SaveModel 通过枚举 Enum 的方式实现: 编辑 详细的 RDD 转换 Sql.DataFrame 可以参考:Spark - RDD / ROW / sql.DataFrame...
