Matrix completion is addressed to recover an unknown large low-rank matrix from a small subset of its entries. Several methods have been proposed for solving matrix completion problem. However, when the desired matrix becomes complicated and the rank is unknown, these traditional methods may not achieve promising performance. In this paper, a novel low-rank matrix completion algorithm based on nuclear...
This paper investigates the design of a heliostat which enhances the efficiency of the light concentrator used in the NLIS (Natural Light Illumination System). The NLIS, a system guiding natural light into buildings for illumination, is installed in smart buildings to reduce energy consumption.
This paper presents an easy matrix computation based simulator of NDN network architecture. This simulator is just like Newtonian mechanics in some way, once given the system initial state, routing table, content distribution, initial data requesting information of NDN network, the simulator can figure out all of the subsequent network state based on matrix operation. This simulator turns packet process...
Based on independent component analysis (ICA), this paper discusses the complex signal model of blind source separation. With discussions of characteristics of complex-valued signals, paper establishes mixed and separated model of complex-valued signals used to define an orthogonal decomposition of the complex-valued space. Using the relative gradients method, based on 4-th order cumulant, it sets...
