What is “truth” anyway? The impact of bias and inadequate ML model validation and what to do about it.

Continuing our 5-part webinar series on the, "Top 5 Pitfalls to Avoid When Developing Your Data Science Team," we are thrilled to interview Randi Ludwig of Dell Technologies and Amarita Natt of Econ One as our panelists. 

We will discuss how data science and engineering teams are affected by insufficient validation of models and methodology. This 45 minute webinar will cover topics including:

  • The importance of the methodological approach for data science within organizations
  • How to structure teams and design processes to reduce bias
  • Quality control measures organizations can deploy to avoid meaningless/incorrect models
  • What role on data science teams is best suited to ensure model quality?
