Exact Sparse Signal Recovery via Orthogonal Matching Pursuit with Prior Information

题目：Exact Sparse Signal Recovery via Orthogonal Matching Pursuit with Prior Information时间：11月20日（周二）下午16:00地点：工商楼105报告人：温金明教授，暨南大学 摘要：Exact recovery of $K$-sparse signals $/x/in /mathbb{R}^{n}$ from linear measurements $/y=/A/x$, where $/A/in /mathbb{R}^{m/times n}$ is a sensing matrix, arises from many applications. The orthogonal matching pursuit (OMP) algorit...

题目：Extreme Quantile Estimation for Autoregressive Models 时间：11月16日（周五）下午15:00 地点：工商楼105报告厅 报告人：黎德元教授 摘要：Quantile autoregresive model is a useful extension to classical autoregresive models as it can capture the influences of conditioning variables on the location, scale and shape of the response distribution. However, at the extreme tails, standard quantile auto...
