This blog is the first in a series that provides a comprehensive overview of a machine learning (ML) shadow platform for model continuous integration /continuous deployment (CI/CD) framework developed at PayPal for end-to-end management of a large cohort of ML models.
这篇博客是系列文章的第一篇，全面介绍了PayPal开发的用于模型持续集成/连续部署（CI/CD）框架的机器学习（ML）影子平台，用于端到端管理大量的ML模型。
Introduction
简介
isk platform is the biggest production AI/ML environment in PayPal. Risk platform enables PayPal to combat sophisticated fraud attacks and cybercrimes in real-time. The platform seamlessly shares intelligence and context across the customer journey while collecting feedback from multiple customer touch points to continuously improve the underlying machine learning (ML) and deep learning (DL) models.
isk平台是PayPal最大的生产型AI/ML环境。风险平台使PayPal能够实时打击复杂的欺诈攻击和网络犯罪。该平台在整个客户旅程中无缝共享情报和背景，同时从多个客户接触点收集反馈，以不断改进底层机器学习（ML）和深度学习（DL）模型。
Due to the regulatory requirements (criticality, high accuracy, and fairness) of these ML/DL models, models and dependent features need to pass through a model CI/CD pipeline and be tested in a ML shadow platform before they are released in a live production environment. The ML shadow platform we built to provide such capabilities is called “Quokka” — a cute, friendly, and approachable creature.
由于这些ML/DL模型的监管要求（关键性、高准确性和公平性），模型和依赖性功能需要通过模型CI/CD管道，并在ML影子平台中进行测试，然后再在实际生产环境中发布。我们为提供这种能力而建立的ML影子平台被称为 "Quokka"--一种可爱、友好、平易近人的生物。

Before we dive into the platform, let’s start with a story. In 1959, Henry Kremer, a British industrialist, had a hypothesis that an airplane could fly by using a pilot’s body power only. He offered £50,000 for the first person to build such a plane. Further, he offered another £100,000 for the first human-powered airplane to fly across the English Channel. After 18 years, dozens of teams tried and failed until Paul MacC...
