웹2024년 3월 29일 · Results show that using variable splitting and Barzilai–Borwein based method to solve the TV-based minimization (TV-VB) can greatly reduce the computation time compared to that of TV-GD. TV-GPEF algorithm has slightly higher computational cost compared to that of the TV-based ones due to the compensation procedure for every iteration. 웹In particular, we analyze and extend the adaptive Barzilai–Borwein method to a new family of stepsizes. While this family exploits negative values for the target, we also consider positive targets. We present a convergence analysis for quadratic problems extending results by Dai and Liao (IMA J Numer Anal 22(1):1–10, 2002), and carry out experiments outlining the … bw-x100g ヨドバシ
