The selection, extraction, and impact of feature engineering on model performance in machine learning

Abstract

 Abstract
 In addition to reviewing the current state-of-the-art regarding the
 mathematical modeling of these systems, their classification, and all the
 control strategies (linear, online , and intelligent) that have been

 developed thus far (i.e., from the year 2000 to date) to control these
 systems, this paper describes some significant classes of two degrees of
 freedom of underactuated mechanical systems. The improvement,
 efficacy, and robustness of the suggested controllers for underactuated
 mechanical systems are discussed, along with future research and
 obstacles
