  This paper is concerned with dynamic system state estimation based on a
series of noisy measurement with the presence of outliers. An incremental
learning assisted particle filtering (ILAPF) method is presented, which can
learn the value range of outliers incrementally during the process of particle
filtering. The learned range of outliers is then used to improve subsequent
filtering of the future state. Convergence of the outlier range estimation
procedure is indicated by extensive empirical simulations using a set of
differing outlier distribution models. The validity of the ILAPF algorithm is
evaluated by illustrative simulations, and the result shows that ILAPF is more
accurate and faster than a recently published state-ofthe-art robust particle
filter. It also shows that the incremental learning property of the ILAPF
algorithm provides an efficient way to implement transfer learning among
related state filtering tasks.
