What you'll learn

Techniques and methods to both identify and deal with label leakage and messy data successfully.

Description

A pervasive but often overlooked problem in predictive modeling on real-life data is the problem of data or label leakage. At Enterprise companies such as Salesforce that provide ML-as-a-service to other businesses, this problem takes on monstrous proportions as the data is populated by diverse and often unknown business processes, making it very hard for data scientists to distinguish cause from effect. In this talk, we will describe how we tackled this problem at Salesforce scale, where we need to churn out thousands of personalized customer-specific machine learning models for any given use case. The automated approaches we describe are a part of our recently open-sourced Spark-based library TransmogrifAI, and extend the boundaries of what typically falls in the domain of “automated machine learning".
