Web23. máj 2024 · In this paper, a weighted l1-norm is proposed in a l1-norm-based singular value decomposition (L1-SVD) algorithm, which can suppress spurious peaks and improve accuracy of direction of arrival (DOA) estimation for the low signal-to-noise (SNR) scenarios. The weighted matrix is determined by optimizing the orthogonality of subspace, and the … WebBoosting Transductive Few-Shot Fine-tuning with Margin-based Uncertainty Weighting and Probability Regularization ...

WebMultiway sparse distance weighted discrimination Bin Guo 1, Lynn E. Eberly; 2, Pierre-Gilles Henry , Christophe Lenglet2, Eric F. Lock1 1 Division of Biostatistics, School of Public Health 2 Center for Magnetic Resonance Research University of Minnesota Abstract Modern data often take the form of a multiway array. Web11. okt 2024 · However, most classification methods are designed for vectors, i.e., 1-way arrays. Distance weighted discrimination (DWD) is a popular high-dimensional classification method that has been extended to the multiway context, with dramatic improvements in performance when data have multiway structure. fran mccaffery brother

WebSparse Distance Weighted Discrimination Boxiang Wang and Hui Zou y First Version: Jun 11, 2014 Second Version: Jan 04, 2015 Abstract Distance weighted discrimination (DWD) was originally proposed to handle the data piling issue in the support vector machine. In this paper, we consider the sparse penalized DWD for high-dimensional classi cation. WebDistance weighted discrimina-tion (DWD) is a popular high-dimensional classi cation method that has been ex-tended to the multiway context, with dramatic improvements in performance when data have multiway structure. However, the previous implementation of multiway DWD was restricted to classi cation of matrices, and did not account for sparsity.
