关于客户
Spark 新西兰是该国最大的电信和数字服务公司。该公司提供移动、宽带和数字服务。在过去的十年中,Spark New Zealand 推出了多项新的数字服务,其中包括支持卫生部门数字化转型的 Spark Health。该公司的高层领导制定了一个雄心勃勃的目标,帮助整个新西兰在数字世界中赢得巨大胜利。为了实现这一目标,他们的目标是详细了解新西兰人的需求和需求。机器学习在这一努力中发挥着至关重要的作用。该公司拥有 50 多个生产模型,以及一支由 20 多名数据科学家和机器学习工程师组成的团队。
挑战
Spark 新西兰是该国最大的电信和数字服务公司,面临着详细了解客户需求以提供更好服务的挑战。该公司的目标是扩大整个组织内机器学习 (ML) 用例的数量,以实现这一目标。他们通过尝试预测客户流失和了解客户偏好开始了机器学习之旅。然而,随着用例数量和团队规模的扩大,他们面临着模型性能和监控的问题。数据的动态特性以及对模型进行持续监控和故障排除的需求带来了重大挑战。每周检查 50 多个模型的性能是一项乏味且耗时的任务。该公司需要一种解决方案来帮助他们更有效地监控这些变化并主动处理模型的输出。
解决方案
为了应对这些挑战,Spark New Zealand 采用 Azure ML 平台进行端到端模型开发和生产。他们还实施了 Arize(一个 ML 可观察性平台)来监控模型性能并进行故障排除。 Arize 因其易用性、计算和可视化数据漂移的能力以及警报功能而被选中。该平台还提供了公平和偏见、绩效跟踪和可解释性工具。借助 Arize,Spark New Zealand 能够监控模型并更好地理解和改进它们。例如,他们可以分析客户是否因为服务或其他原因而离开,以及这些功能是否捕获了该行为。如果没有,他们可以进行一些特征工程,将注意力集中在根据反馈改进模型的方法上。该公司还使用 Arize 将模型预测与业务投资回报或其他关键绩效指标 (KPI) 联系起来。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
