This paper surveys main principles of feature selection and their recent applications in big data bioinformatics. Instead of the commonly used categorization into filter, wrapper, and embedded approaches to feature selection, we formulate feature selection as a combinatorial optimization or search problem and categorize feature selection methods into exhaustive search, heuristic search, and hybrid...
Due to the increasing importance of trust in online transactions, the seller reputation system has become a widely used method for creating trust among the transactors and providing incentives for good behaviors in online transactions. A robust reputation system is considered crucial for building a better marketplace for various types of e-commerce. However, false reputation seriously affect the effectiveness...
In this paper, a robust control strategy for uncertain nonlinear continuous-time plants with disturbances and state delays is proposed. The strategy is based on the uncertainty and disturbance estimator (UDE). Both cases with known and unknown delay are considered. In the case of an unknown time delay, the term with the delay is treated as an additional disturbance to the system. Both nonlinear and...
In this paper, necessary and sufficient conditions for the approximate controllability of a large class of neutral systems in reflexive Banach spaces in investigated. The approach is based on the transformation of such systems into appropriate boundary control systems.
