Combined Belief Propagation-Mean Field Message Passing Algorithm for Dirichlet Process Mixtures

2019 · IEEE Signal Processing Letters

This letter deals with variational inference for Dirichlet process mixtures (DPM) models. We propose a combined message-passing algorithm introducing belief propagation (BP) into the original mean field (MF) rules, which leads to a more precise …

Fast Detection Algorithm for Equal Length Frame Signals Based on Pattern Matching

2023

Aiming at the problems of slow speed and low efficiency of the existing signal frame header detection algorithm in the field of cooperative communication, a pattern matching based frame header detection algorithm is proposed. The …
