The installation, PP Trees, evolved from techniques and experiments developed during production of the Meltdown Series. The installation is both an expression of the capabilities of the material from which it is made - polypropylene pipe - and also an examination of attitudes towards plastics and our perception of beauty.

2019年5月2日 · Projection pursuit classification tree using LDA, Lr or PDA projection pursuit index

This new proposed algorithm, the projection pursuit classification tree (PP-tree), uses projection pursuit to find good low-dimensional projections revealing separations between classes, and uses these as variables for splitting, to build a more simply structured tree where there is correlation between the original variables.

Projection pursuit classification tree using LDA, Lr or PDA projection pursuit index

2013年1月1日 · In this paper, we propose a new classification tree, the projection pursuit classification tree (PPtree). It combines tree structured methods with projection pursuit dimension reduction.

2019年5月6日 · Find tree structure using various projection pursuit indices of classification in each split.

Find tree structure using projection pursuit in each split. PP.Tree(PPmethod, i.class, i.data, weight = TRUE, r = NULL, lambda = NULL, cooling = 0.999, temp = 1, energy = 0.01, ...) ... n <- …
