Value Range

Why Monitor Value Range?

Monitoring changes in the value range of numeric fields helps to locate and examine anomalies in the model's input.

For example, setting the monitor for a feature named hour_sin with the range -1 <= x <= 1 will help us discover issues in model input.

Comparison methods

For this monitor, the following comparison methods are available:

• Change in percentage

• Absolute value

• Compared to segment

• Compared to training

Customizing your monitor

Configuration may slightly vary depending on the comparison method you choose.

STEP 1: choose the fields you would like to monitor

You may select as many fields as you want (from features/raw inputs) 😊

Note that the monitor will run on each selected field separately.

STEP 2: choose inspection period and baseline

For the fields you chose in the previous step, the monitor will raise an alert if the value range in the inspection period exceeds your threshold boundaries compared to the baseline's value range.

STEP 3: calibrate thresholds

This step is important to make sure you have the right amount of alerts that fits your needs. You can always readjust it later if needed.
