The objective of subgroup discovery is to find groups of individuals who are statistically different from others in a large data set. Most existing measures of the quality of subgroups are intuitive and do not precisely capture statistical differences of a group with the other, and their discovered results contain many redundant subgroups. Odds ratio is a statistically sound measure to quantify...

The method of statistical determination of smallest bans of probability measures on discrete spaces is offered. Consistency of the constructed estimates is shown. The application of the received estimates for testing of statistical hypotheses in the discrete spaces is constructed. It is shown that estimates of bans can generate consistent sequences of criteria in some sense.

Facial surgeons require a vast amount of knowledge about the human face, in order to decide how to reconstruct an injured or traumatized part. Does this knowledge consist only of explicit notions about face anatomy, or is there also an implicit knowledge of the normal appearance of a face? And if the answer to the latter question is affirmative, is there a way for a computer to automatically le...

Automatic specialization of algorithms to a limited domain is an interesting and industrially applicable problem. We calculate the optimal assignment of computational resources to several different solvers that solve the same problem. Optimality is considered with regard to the expected solution time on a set of problem instances from the domain of interest. We present two approaches, a static ...

Quantitative estimation of hair growth using hair weight and number was recorded for 120 weeks in 4 groups of 9 men with androgenetic alopecia. Three double-blind groups applied either 2% or 5% minoxidil solution, or vehicle. The fourth group, unblinded, received no treatment. Measurements of hair weight and number were continued for 96 weeks, when treatment (if any) was stopped, though measure...
