Type: Package Package: fastcpd Title: Fast Change Point Detection via Sequential Gradient Descent Version: 1.2.2 Authors@R: c( person("Xingchi", "Li", , "anthony.li.stat.tamu.edu@lixingchi.com", role = c("aut", "cre", "cph"), comment = c(ORCID = "0009-0006-2493-0853")), person("Xianyang", "Zhang", , "zhangxiany@stat.tamu.edu", role = c("aut", "cph")) ) Description: Implements fast change point detection algorithm based on the paper "Sequential Gradient Descent and Quasi-Newton's Method for Change-Point Analysis" by Xianyang Zhang, Trisha Dawn . The algorithm is based on dynamic programming with pruning and sequential gradient descent. The C++ core is also exposed through a standalone C++ library interface for non-R consumers.
