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.

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.

Now, you can easily customize the pre-built Evidently reports to add your metrics, statistical tests or change the look of the dashboards with a bit of Python code.

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.

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.

Is it time to retrain your machine learning model? Even though data science is all about… data, the answer to this question is surprisingly often based on a gut feeling. Can we do better?

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.

Who should care about machine learning monitoring? The short answer: everyone who cares about the model's impact on business.

Congratulations! Your machine learning model is now live. Many models never make it that far. Some claim, as much as 87% are never deployed.
