Application of Projection Pursuit Dynamic Cluster Model in Water Resources Assessment
工程科学与技术, 2008 :A projection pursuit dynamic cluster model is developed, and it is used in water resources assessment for the first time.The projection pursuit dynamic cluster model combines projection pursuit principle with dynamic cluster method.Firstly,multifactor ...

Determining the number of clusters using nonparametric statistics
Lietuvos Matematikos Rinkinys, 1997 A Gaussian mixture model is investigated in this paper. A method for estimation of unknown number of clusters in the case of equal covariance matrices is discribed. This method is based on the use of projection pursuit.

Robust sparse principal component analysis. [PDF]
A method for principal component analysis is proposed that is sparse and robust at the same time. The sparsity delivers principal components that have loadings on a small number of variables, making them easier to interpret.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Data processing method for telecom data based on projection pursuit
Dianxin kexue, 2016 In the big data era, the data which operator can collect and process is quickly growing. At the same time, due to the high dimension of the data, it is very difficult to extract and process information from them.

Combining Exploratory Projection Pursuit And Projection Pursuit Regression With Application To Neural Networks [PDF]
, 1992 We present a novel classification and regression method that combines exploratory projection pursuit (unsupervised training) with projection pursuit regression (supervised training), to yield a new family of cost/complexity penalty terms.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Preserving the clustering structure by a projection pursuit approach [PDF]
, 2009 A projection pursuit technique to reduce the dimensionality of a data set preserving the clustering structure is proposed. It is based on Silverman’s (J R Stat Soc B 43:97–99, 1981) critical bandwidth.We show that critical bandwidth is scale equivariant ...
