?...与FP-Growth算法不同之处在于,将每一条事务插入到FP-Tree的过程的同时,需要额外构建了一个二维矩阵,称之为FP-Array,来记录与每一个数据项共同出现的数据项的支持度计数,如下图所示。...删除不满足阈值的数据项后,按照支持度计数递减排序。然后,将上述计算结果分组,并为每一个组分配一...

我已经试过你的代码,它工作得很完美。我唯一更改的是tableId = test-dev.xpto.array到table_id = 'my-project.my_dataset.my_table'的行,以匹配job中的参数。 如何在Python中的BigQuery结果变量中使用f字符串? 这个问题和错误与BigQuery无关。您不能那样使用f-strings;这个简短的示例演示了相同的问题: for ...

This is significant because the errors array may now be present for passing jobs, however these errors should serve more as warnings. If your application logic depended on this functionality you'll need to manually check for errors now.
要获取数组中的最后一个元素,可以使用以下方法 select array_reverse(your_array)[offset(0)] 我不确定如何在我的代码中结合这一点 select type, array_reverse(array( select trim(val) from unnest(split(trim(payload, '[]'))) val ))[offset(0)] from `githubarchive.day.20210606`where type = 'Memb...
