Support

Feature analytics is supported for any model task type, but does not support time stamps or columns of type string or vector.

Available Right-Side Controls

Parameter	Value
Model	List of models in the project
Version	List of versions for the selected model
Environment	`Production` or `Pre-Production`
Dataset	Displayed only if `Pre-Production` is selected. List of pre-production env uploaded for the model version.
Visual	List of possible visualizations, Feature Distribution or Feature Correlation.
Segment	<p>- Selecting a saved segment<br>- Defining an applied (on the fly) segment. This applied segment isn’t saved (unless specifically required by the user) and is applied for analysis purposes.</p>
Feature	<p>- Feature Distribution: Select a single column of a supported data type to view the distribution of its values<br>- Feature Correlation: Select two columns to visualize their correlation<br>- Correlation Matrix: Select up to eight columns to visualize their pairwise correlations</p>

Available In-Chart Controls

Control	Value
Time range selection	Selecting start time and end time or time label for production data. Default is last 30 days
Display	Select how to display the chart, Histogram or Kernel Density Estimate, depending on the data type of the feature selected.

Displays for Feature Distribution

Kernel Density Estimate

For numeric column types, visualize feature distribution as a Kernel Density Estimate chart. Feature distribution chart configured with Kernel Density Estimate rendering

Histogram

Categorical and boolean value may only be displayed as Histograms, but other column types may also be displayed as such. Feature distribution chart configured with histogram rendering

Displays for Feature Correlation

Line Plot

Scatter Plot

Stacked Bar Plot

Stacked bar example of Feature Correlation chart

Box Plot

Correlation Matrix Interactions

Clicking a cell in the correlation matrix opens the Feature Correlation chart, enabling a more detailed analysis of the relationship between the selected features. Correlation matrix interactions
