Computationally Efficient Compressed Sensing-Based Method via FG Nyström in Bistatic MIMO Radar with Array Gain-Phase Error Effect

International Journal of Antennas and Propagation, 2020
In this paper, a robust angle estimator for uncorrelated targets that employs a compressed sense (CS) scheme following a fast greedy (FG) computation is proposed to achieve improved computational efficiency and performance for the bistatic MIMO radar ...

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Simultaneous greedy approximation in Banach spaces

Journal of Complexity, 2005
The notion of the weak greedy algorithms (WGA) in the case of Hilbert space \(H\) was introduced and studied by the second author [Adv. Comp. Math. 12, 213--227 (2000; Zbl 0964.65009)]. This algorithm is provided for each \(f\in H\) and any dictionary \(\mathcal{D} \) by the sums \(G_m(f,\mathcal{D})\) \(=\sum _{j=1}^mc_j\varphi _j(f),\) where \(m\in N

Simple Stopping Criteria for Information Theoretic Feature Selection

Entropy, 2019
Feature selection aims to select the smallest feature subset that yields the minimum generalization error. In the rich literature in feature selection, information theory-based approaches seek a subset of features such that the mutual information between
