  1. Localization error (LE) of FLSQ with R i  = 3 due to variations of the model parameters. LE = 1 100 l = 1 100 E l (x x ̂ Q 2 ), where E l is the average localization error for the l th five-sensor configuration and is expressed in meters. LE (normal) is for the test set from normal distribution with a mean of (5,5) and unit variance and LE (uniform) from uniform distribution.
