Kullback-Leibler Approach to Gaussian Mixture Reduction A common problem in multi-target tracking is to approximate a Gaussian mixture by one containing fewer components; similar problems can arise in integrated... AR Runnalls - 《Aerospace & Electronic Systems IEEE Transactions on》 被引量: 301发表...
This study presents a global Gaussian mixture reduction (GMR) algorithm via clustering, which is based on a fuzzy adaptive resonance theory (FART) neural network architecture. Therefore the authors call the proposed algorithm as GMR based on the fuzzy ART (GMR-FART) in this study. The ...

We call this procedure Gaussian Mixture Classification (GMC).For a given GMR or GMC model, forward and backward projection algorithms are implemented to locate the optimal subspaces that minimize information loss. They serve as the model-based dimension reduction techniques for GMR and GMC.In ...

Then, Gaussian mixture component reduction technique is introduced [58]. The technique can handle multiple input correlations. c) Sequence operation theory: Sequence operation theory (SOT) based framework requires the knowledge of probability sequence. When SOT is applied to PLF, PMFs of input RVs ...
It is well known that the Gaussian mixture model (GMM) is the most popular data model. Since the prior probability of each Gaussian component is typically not given, known as latent variables, the correct parameters of GMM are solved using the expectation-maximization (EM) algorithm. ...
