What is feature encoding for cyclical variables?
Updated May 16, 2026
Short answer
Cyclical encoding represents periodic features like time using sine and cosine transformations.
Deep explanation
Features like hour of day or day of week are cyclical, meaning 23 is close to 0. Linear encoding fails to capture this. Sine and cosine transformations preserve circular relationships in feature space.
