A Gaussian smoothing-based zeroth-order method for Goldstein second-order stationarity
Ming Lei, Ting Kei Pong, Man-Chung Yue +2
We introduce a new generalized Hessian, called the Goldstein second-order -subdifferential, and an associated notion of -second-order stationary point for conti…
Chirp Parameter Optimization and Distributed Detection for Cooperative RSMA-AFDM Systems
Qingyu Li, Guanghui Liu, Yusha Liu +4
Affine frequency division multiplexing (AFDM) exhibits excellent Doppler robustness and the ability to characterize doubly selective channels. However, its signal dispersion charac…
A single-loop proximal-conditional-gradient penalty method
Hao Zhang, Liaoyuan Zeng, Ting Kei Pong
We consider the problem of minimizing a convex separable objective (as a separable sum of two proper closed convex functions and ) over a linear coupling constraint. We assu…
Convergence analysis for a variant of manifold proximal point algorithm based on Kurdyka-Åojasiewicz property
Peiran Yu, Liaoyuan Zeng, Ting Kei Pong
We incorporate an iteratively reweighted strategy in the manifold proximal point algorithm (ManPPA) in [12] to solve an enhanced sparsity inducing model for identifying sparse yet…
