Impact of BPL penalty functions and PSF models in PET/CT radial spatial resolution recovery by Si, Wang Jie

“…However, OSEM often struggles with full convergence, necessitating BPL with smooth penalty functions (β values) for regularized iterative reconstruction. Since National Cancer Institute (NCI) currently practice OSEM+TOF+PSF+BPL (β 450) as the in-house protocol, this study explores alternative BPL and PSF functions in OSEM to enhance spatial resolution and determine optimal β values for NCI's routine clinical use. …”

话语标记 “可是” 在马来西亚华语会话中的语用功能 = Pragmatic functions of discourse marker “Keshi” in conversational Malaysian Mandarin by 胡文绮 Woo, Wen Qi

“…In certain contexts of daily conversation, the original sematics of “keshi” weakens, yet this phenomenon simultaneously reveals and displays certain regularities. Previous research have investigated extensively the truth value semantics of “keshi” based on written Mandarin, however, this paper finds that the various uses of “keshi” in natural conversations can hardly be explained with such semantics. …”

Adversarial robustness of deep reinforcement learning by Qu, Xinghua

“…Motivated by this finding, we propose a new policy distillation loss with two terms: 1) a prescription gap maximization loss aiming at simultaneously maximizing the likelihood of the action selected by the teacher policy and the entropy over the remaining actions; 2) a corresponding Jacobian regularization loss that minimizes the magnitude of gradient with respect to the input state. …”

Development of schlieren-image based flow diagnostics and analysis for supersonic jet flows by Lim, Desmond Haoxiang

“…The optical flow algorithm incorporated modern minimization methods with second order div-curl regularizer and robust penalty functions. As a result, it outperformed a competitive open source optical flow algorithm in a synthetic validation test, with an average endpoint error of 0.701. …”
