Shift happens: we compared 5 methods to detect drift in ML embeddings

May 17, 2023

Monitoring embedding drift is relevant for the production use of LLM and NLP models. We ran experiments to compare 5 drift detection methods. Here is what we found.

ML model maintenance. “Should I throw away the drifting features”?

October 26, 2022

Imagine you have a machine learning model in production, and some features are very volatile. Their distributions are not stable. What should you do with those? Should you just throw them away?

Q&A: ML drift that matters. "How to interpret data and prediction drift together?"

April 25, 2022

Data and prediction drift often need contextual interpretation. In this blog, we walk you through possible scenarios for when you detect these types of drift together or independently.

Q&A: Do I need to monitor data drift if I can measure the ML model quality?

December 9, 2021

Even if you can calculate the model quality metric, monitoring data and prediction drift can be often useful. Let’s consider a few examples when it makes sense to track the distributions of the model inputs and outputs.
