Deep learning (DL) has emerged as an effective tool for channel estimation in wireless communication systems, especially under some imperfect environments. However, even …
Weak Convergence Page 1 1.3 Weak Convergence In this section IDl and IE are metric spaces with metrics d and e, respectively. The set of all continuous, bounded functions f: IDl 1--+ IR is …
The regression estimation problem has a long history. Already in 1632 Galileo Galilei used a procedure which can be interpreted as? tting a linear relationship to contaminated observed …
The theory of empirical processes provides valuable tools for the development of asymptotic theory in (nonparametric) statistical models, and makes it possible to give a unified treatment …
We introduce a family of adaptive estimators on graphs, based on penalizing the l 1 norm of discrete graph differences. This generalizes the idea of trend filtering (Kim et al., 2009; …
