Estimates on the dimension of self-similar measures with overlaps
De-Jun Feng, Zhou Feng
In this paper, we provide an algorithm to estimate from below the dimension of self-similar measures with overlaps. As an application, we show that for any , the dimen…

The unified theoretical frame of logarithmic alternative model for sparse information recovery and its application in multiple source location problem by TDOA
Wang Changlong, Zhou Feng, Wang Weichao +1
In sparse information recovery, the core problem is to solve the -minimization which is NP-hard. On one hand, in order to recover the original sparse solution, there are a lot…
