Quasi-constant feature count

​

Definition

The quasi-constant feature count test allows you to specify a threshold on the number of features that are near-constant (low variance).

​

Taxonomy

• Category: Integrity.
• Task types: Tabular classification, tabular regression.
• Availability: development and monitoring.

​

Why it matters

• Quasi-constant features have very low variance and tend to not be as useful for models.
• If a feature shouldn’t be quasi-constant but is, you might want to re-normalize it.
