Multi-stage optimization of decision trees: Two applications
M
ulti-stage optimization of decision trees is one of the extensions of dynamic programming. It allows us to optimize
decision trees sequentially relative to a number of cost functions. We will discuss two applications of this technique:
finding of minimum average depth of a decision tree for sorting eight elements and creation of an algorithm for reduct
minimization. The question about minimum average depth of a decision tree for sorting of eight elements was open since
1968 and was considered by D Knuth in his famous book
The Art of Computer Programming
, Volume 3, Sorting and Searching.
Reduct is a minimal set of conditional attributes in a decision table which gives the same information about decision attribute
as the whole set of conditional attributes. The problem of reduct minimization is closely connected with the feature selection.
The end of the presentation is devoted to the introduction to KAUST.
