Struct MaxAbsScaler 

pub struct MaxAbsScaler;

Parameters for MaxAbsScaler (unfitted state).

Scales each feature by its maximum absolute value so that the resulting values lie in the range [-1, 1]. Unlike StandardScaler or RobustScaler, this scaler does not center the data, which makes it suitable for sparse data.

x_scaled[i, j] = x[i, j] / max_abs[j]
