Abstract
In this paper the Bias Variance Search Algorithm is proposed
as an algorithm to optimize a candidate set of initial parameters
for an Extended Kalman filter (EKF). The search algorithm
operates on a Bias Variance Equilibrium Point criterion
to determine how to set the initial parameters. The candidate
set is then used by the EKF to estimate state parameters
to fit a triply modulated cosine function to time series of the
first two spectral bands of the MODerate-resolution Imaging
Spectroradiometer (MODIS) land product. The state parameters
are then used for land cover classification. The results
of the search algorithm was tested on classifying land cover
in the Limpopo province, South Africa. An improvement in
land cover classification was observed when the method was
compared to a robust regression method.
