``ML Parameter Estimation of a Multiscale Stochastic Process using the EM Algorithm,''
IEEE Transactions on Signal Processing, to appear June 2000.

An algorithm for estimation of the parameters of a multiscale stochastic process based on scale-recursive dynamics on trees is presented. The expectation-maximization algorithm is used to provide maximum likelihood estimates for the general case of a non-homogeneous tree with no fixed structure for the process dynamics. Experimental results are presented using synthetic data.
