About this Episode


Data is often messy or incomplete, requiring human intervention to make sense of it before being usable as input to machine learning projects. This is problematic when the volume scales beyond a handful of records. In this episode Dr. Cheryl Martin, Chief Data Scientist for Alegion, discusses the importance of properly labeled information for machine learning and artificial intelligence projects, the systems that they have built to scale the process of incorporating human intelligence in the data preparation process, and the challenges inherent to such an endeavor.

    • What tools and processes do you have in place to ensure the accuracy of their inputs?
    • How do you prevent bad actors from contributing data that would compromise the trained model?

  • What are the limitations of crowd-sourced data labels?

    • When is it beneficial to incorporate domain experts in the process?

  • When doing data collection from various sources, how do you ensure that intellectual property rights are respected?

  • How do you determine the taxonomies to be used for structuring data sets that are collected, labeled or enriched for your customers?

    • What kinds of metadata do you track and how is that recorded/transmitted?

  • Do you think that human intelligence will be a necessary piece of ML/AI forever?
