Variable Step Size Adams Methods for BSDEs
Journal of Mathematics, 2021 For backward stochastic differential equations (BSDEs), we construct variable step size Adams methods by means of Itô–Taylor expansion, and these schemes are nonlinear multistep schemes.

A Variable Step‐Size Leaky LMS Algorithm [PDF]
Wireless Communications and Mobile Computing, 2021 The leaky LMS algorithm has been extensively studied because of its control of parameter drift. This unexpected parameter drift is linked to the inadequacy of excitation in the input sequence. And generally leaky LMS algorithms use fixed step size to force the performance of compromise between the fast convergence rate and small steady‐state ...
