The modified second APG method for DC optimization problems

The Modified BAPG<i><sub>s</i></sub> Method for Support Vector Machine Classifier with Truncated Loss

“…In this section, we first describe the BAPG s method proposed in [14], then the modified BAPG s method with adaptive parameter is given for HTPSVM.…”

“…The APG algorithm was used to solve the model in [11]. [12] applied the APG s method (first proposed in [13]) to solve problem (1) and obtain better convergence behavior. However we find that the proximal operator for computing the 1 l norm causes the subproblem to be solved slowly in APG and APG s algorithms, we attempt to accelerate the solution process for this model.…”

“…However we find that the proximal operator for computing the 1 l norm causes the subproblem to be solved slowly in APG and APG s algorithms, we attempt to accelerate the solution process for this model. Recently, [14] propose the Bregman APG s (BAPG s ) method, which avoids the restrictive global Lipschitz gradient continuity assumption. In this paper, we improve BAPG s algorithm to solve the problem (1) and replace the Lipschitz constant by an appropriate positive definite matrix and obtain better results after we perform numerical experiments on 10 datasets to test our method.…”

“…In the next section, we provide preliminary materials used in this work. In Section 3, we introduce the BAPG s algorithm proposed by [14] and present our algorithm based on the BAPG s me- thod for solving the HTPSVM model (1). The convergence of our method is also discussed.…”

Compliance and governance: evidence from financial institutions in Taiwan

“…The evaluation of the Asia Pacific Group (APG) on money laundering in 2018 also led to a strong determination on the part of Taiwan’s Government to comprehensively enhance regulatory compliance among financial institutions. Although Taiwan was a founding member of the APG and was the first one to promulgate laws against money laundering in Asia, Taiwan was downgraded in 2007 and again in 2011 until 2015 (Lin, 2018) because of poor performance of money laundering. Taiwan’s Government was aware that a poor APG evaluation result would lead to a strict review of all cash flows from companies in Taiwan, which would negatively impact not only firms’ business operations but also Taiwan’s national reputation and future economic development.…”
