中文说明：应用背景我们考虑选择一组钾的问题传感器测量，从一组可能的或潜在的传感器测量，最大限度地减少了误差，在估计一些参数，使用凸优化关键技术我们描述基于凸优化的启发式近似求解这个问题。我们的启发式给出了一个子集的选择，以及一个可以实现的最佳性能的约束传感器测量的选择
English Description：
Application backgroundWe consider the problem of choosing a set of k sensor measurements, from a set of m possible or potential sensor measurements, that minimizes the error in estimating some parameters using convex optimizationKey Technologywe describe a heuristic, based on convex optimization, for approximately solving this problem. Our heuristic gives a subset selection as well as a bound on the best performance that can be achieved by any selection of k sensor measurements
