Abstract To improve the efficiency of dim point target detection based on dynamic programming (DP), this paper proposes a multi-frame method DP ring network (DPRN). In proposed method, first, trajectory is approximated using piecewise linear function. The velocity space partition (VSP-DP) used to accumulate merit functions each segment avoid function diffusion in different spaces. addition, mat...

Change point detection algorithms have numerous applications in areas of medical condition monitoring, fault industrial processes, human activity analysis, climate change detection, and speech recognition. We consider the problem on compositional multivariate data (each sample is a probability mass function), which practically important sub-class general data. While change-point well studied un...
