Abstract
A bio-signal feature scaling apparatus may include: a processor configured to execute instructions to: extract a feature from a bio-signal of an object; estimate a cause of change in a bio-state of the object; calibrate a scale factor based on the estimated cause of change in the bio-state; and scale the extracted feature by applying the calibrated scale factor to the extracted feature.
