自动化和规模化

这其中的每一个问题都有无数的解决方案,但是有一件事是确定的:它们是非常适合自动
化的任务。它们的输出和步骤非常清晰。它们有一个有限但特定的听众群体。它们有确定
的时间或事件来触发行动。此外,在特定的环境下它们都是可以用脚本和程序解决的事情。
当任务清晰、定义完整,并且输出非常容易确定的时候,自动化是最容易的。不管怎样,
即使输出并不总是很容易测试或预测,自动化也可以帮助完成任务的一部分,把剩余的留
给你(或其他人)更细致地研究和分析。你可以想象这里的自动化类似于你在生活中自动
化其他的事情。你可能有一个最喜欢的已保存的比萨订单,或者一个邮件的自动回复。如
果一个任务输出明确并定期发生,那么这是一个很适合自动化的任务。
但是什么时候不应该自动化呢?以下条件预示着该任务不是一个好的自动化选择。
任务很少发生,并且非常复杂,自己做更好(例如,填写报税单)。
任务的成功输出很难确定(例如,小组讨论、社会研究或调查)。
任务需要与人交互来确定合适的完成方式(例如,交通导航、诗歌翻译)。
任务成功是当务之急。
其中的一些例子,尤其是需要人工输入的例子,适合一定程度的自动化。有些任务可以通
过让机器寻找建议来做部分自动化,之后再确定这些建议是对还是错(使用人工反馈的机
器学习)。其他的任务,比如少见又复杂的任务,或者是非常重要的商业任务,随着对任
务的熟悉,可能最后会实现自动化或部分自动化。但是你可以看到整体的逻辑来确定什么
时候自动化更好,什么时候这不是一个好的想法。
如果你不确定自动化是否适合你 ...
