用于机器学习的开放数据集有哪些呢?Lionbridge 团队为高质量的数据集创建了一份最终备忘单。这些高质量的数据集或者涵盖范围广泛(比如 Kaggle),或者非常细化(比如自动驾驶汽车的数据)。
首先,在搜索数据集时要记住几点。Dataquest 是这么说的:
数据集不应脏乱,这样就无需花太多时间来清洗……
Industries and organizations are being greatly transformed by data and analysis. The field of data analytics has seen a massive shift where people are adapting the analytics to suit them rather than adapting their ways to fit in with traditional forms of analysis.
The power of data analysis is b……

The process of creating an application with embedded dashboards, reporting, and analytics capabilities is complex. It doesn’t just stop with taking information and making it available to end users in dashboards and reports. Application users are demanding advanced features that allow them to exami……
It’s one of the most memorable day of my lifetime,
And it had been a great experience with you.
We are not always lucky to find good friends among colleagues,
May our friendship remains even after we change the path.
Good Times + Crazy Friends = Amazing Memories,
Forever Friends, Boss, Broth……

当我十七岁的时候,我读到了一句话:“如果你把每一天都当作生命中最后一天去生活的话,那么有一天你会发现你是正确的。”这句话给我留下了一个印象。从那时开始,过了33年,我在每天早晨都会对着镜子问自己:“如果今天是我生命中的最后一天,你会不会完成你今天想做的事情呢?……
使用 PolyBase 是将大量数据加载到高吞吐量 Azure SQL 数据仓库的有效方法。 使用 PolyBase 而非默认 BULKINSERT 机制可以实现吞吐量的巨大增加。
如果源数据位于 Azure Data Lake Storage Gen2 中,且格式与 PolyBase 兼容,则可使用复制活动直接调用 PolyBase,让 Azure SQL 数据仓库从源拉取数据。
如果 PolyBase 最……
将数据复制到 Azure SQL 数据库时,可能需要不同的写入行为:
追加:我的源数据只包含新记录。
更新插入:我的源数据包含插入和更新内容。
覆盖:我需要每次都重新加载整个维度表。
使用自定义逻辑进行写入:在将数据最终插入目标表之前,我需要额外的处理。
