Most business processes are, by nature, multivariate and autocorrelated. Highdimensionality is rooted in processes where more than one variable is considered simultaneously to provide a more comprehen...
Dimension reduction in representation of the data
Data representation data analysis data mining

Suppose the data consist of a set S of points xj , 1 ≤ j ≤ J, distributed in a
bounded domain D RN, where N is a large number. An algorithm is given
for finding the sets Lk of dimension k N, k = 1, ...
Dimension reduction based on constrained canonical correlation and variable filtering

The “curse of dimensionality” has remained a challenge for highdimensional
data analysis in statistics. The sliced inverse regression
(SIR) and canonical correlation (CANCOR) methods aim to reduce
...

The statistical problem of estimating the effective dimensionreduction
(EDR) subspace in the multi-index regression model with
deterministic design and additive noise is considered. A new procedure

In this paper, we propose two new methods to estimate the dimensionreduction
directions of the central subspace (CS) by constructing a regression
model such that the directions are all captured in t...
