When one mentions "ML monitoring," this can mean many things. Are you tracking service latency? Model accuracy? Data quality? This blog organizes everything one can look at in a single framework.
We ran an experiment to help build an intuition on how popular drift detection methods behave. In this blog, we share the key takeaways and the code to run the tests on your data.
Our CTO Emeli Dral gave a tutorial on how to use Evidently at the Stanford Winter 2022 course CS 329S on Machine Learning System design. Here is the written version of the tutorial and a code example.
What can go wrong with ML model in production? Here is a story of how we trained a model, simulated deployment, and analyzed its gradual decay.
No model lasts forever. While the data quality can be fine, the model itself can start degrading. A few terms are used in this context. Let’s dive in.
In this series of blogs, we are showcasing specific features of the Evidently open-source ML monitoring library. Meet NoTargetPerformance test preset!
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?
There is an overwhelming set of potential metrics to monitor. In this blog, we'll try to introduce a reasonable hierarchy.
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.
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.
What can you do once you detect data drift for a production ML model? Here is an introductory overview of the possible steps.
When monitoring ML models in production, we can apply different techniques. Data drift and outlier detection are among those. What is the difference? Here is a visual explanation.
You can look at historical drift in data to understand how your data changes and choose the monitoring thresholds. Here is an example with Evidently, Plotly, Mlflow, and some Python code.
Our second report is released! Now, you can use Evidently to explore the changes in your target function and model predictions.
