The purpose of feature selection is selection of the least number of features in order to increase accuracy and decrease the cost of data classification.

In applications of learning from examples to real-world tasks, feature subset selection is important to speed up training and to improve generalization performance. Ideally, an inductive algorithm should use subset of features as small as possible. In this paper however, the authors show that the problem of selecting the minimum subset of features is NP-hard. The paper then presents a greedy algorithm for feature subset selection. The result of running the greedy algorithm on hand-written numeral recognition problem is also given.

Metrics details. Methods for extracting useful information from the datasets produced by microarray experiments are at present of much interest. Here we present new methods for finding gene sets that are well suited for distinguishing experiment classes, such as healthy versus diseased tissues.

Metrics details. Current - omics technologies are able to sense the state of a biological sample in a very wide variety of ways.

Рванувшись вниз за своей жертвой, он продолжал держаться вплотную к внешней стене, что позволило бы ему стрелять под наибольшим углом. Но всякий раз, когда перед ним открывался очередной виток спирали, Беккер оставался вне поля зрения и создавалось впечатление, что тот постоянно находится впереди на сто восемьдесят градусов. Беккер держался центра башни, срезая углы и одним прыжком преодолевая сразу несколько ступенек, Халохот неуклонно двигался за. Еще несколько секунд - и все решит один-единственный выстрел.

Он застонал. Проклятые испанцы начинают службу с причастия. ГЛАВА 92 Сьюзан начала спускаться по лестнице в подсобное помещение. Густые клубы пара окутывали корпус ТРАНСТЕКСТА, ступеньки лестницы были влажными от конденсации, она едва не упала, поскользнувшись. Она нервничала, гадая, сколько еще времени продержится ТРАНСТЕКСТ.

Они пощупали пульс и увезли его, оставив меня один на один с этим идиотом-полицейским.
