Feb 18, 2019 When spiral classifiers for sand washing and dewatering, the production capacity is generally calculated according to the amount of sand returned, and the control particle size and allowable feed flow rate are checked according to the overflow speed.. 2.Hydrocyclone. Hydrocyclone is a type of classifier that is for the fines classification and dewatering by centrifugal force.
Aug 21, 2019 The principle of any approach for solving feature selection problem is to find a subset of the original features. Since finding a minimal subset of the features is an NP-hard problem, it is necessary to develop and propose practical and efficient heuristic algorithms. The whale optimization algorithm is a recently developed nature-inspired meta-heuristic optimization algorithm that imitates ...
Jul 29, 2019 The process of dimensionality reduction is a crucial solution to deal with the dimensionality problem that may be faced when dealing with the majority of machine learning techniques. This paper proposes an enhanced hybrid metaheuristic approach using grey wolf optimizer GWO and whale optimization algorithm WOA to develop a wrapper-based feature selection method. The main
