Since the podcast was recorded, a lot has happened at Evidently! You can use this open-source tool ( to generate a variety of interactive reports on the ML model performance and integrate it into your pipelines using JSON profiles.

This monitoring tutorial is a great showcase of what can go wrong with your models in production and how to keep an eye on them:

About The Show

Datacast features long-form conversations with practitioners and researchers in the data community to walk through their professional journey and unpack the lessons learned along the way. I invite guests coming from a wide range of career paths - from scientists and analysts to founders and investors — to analyze the case for using data in the real world and extract their mental models (“the WHY”) behind their pursuits. Hopefully, these conversations can serve as valuable tools for early-stage data professionals as they navigate their own careers in the exciting data universe.
