A Review on Feature Selection for Bioinformatics

We summarize feature selection approaches with recent applications in bioinformatics. We suggest to deviate from the commonly used categorization of feature selection approaches into filter, wrapper, and embedded approaches. Instead, we view feature selection as a combinatorial optimization or a search problem, by classifying feature selection approaches into exhaustive search, heuristic search,and hybrid methods, with heuristic search approaches further divided into those with or without feature...

Coverage Enhancement Based on Iterated Weighted RFGP Algorithm in DSNs

In this study, a novel distributed coverage-enhancing algorithm, IW-RFGP, was proposed.This algorithm determines the new working direction of a directional sensor node according to the virtual attractive force of uncovered grid points in sensing field.It overcomes the shortcomings of other coverage-enhancing algorithms,such as complicated algorithmic procedure and low rate of convergence.Simulation results show that the algorithm is correct and effective,and has fast convergence speed and signifi...

Influence of Moisture Content on the Flow Properties of Fugu Pulverized Coal

Flowability of Fugu pulverized coal on different moisture content was investigated by Jenike shear test system and FT4 Powder Rheometer from Freeman technology.Flow function,internal friction,cohesion,wall friction,compressibility percentage,permeability and flow energy were determined.The results show that the pulverized coal had better flow properties,fine permeability,slight cohesion and hard internal friction when the moisture content was between 3 ％ and 4 ％.When the moisture content increa...

Existence and Uniqueness of Positive Solutions for a Class of Fractional Differential Equations with Integral Boundary Condition

In this paper,we consider existence and uniqueness of positive solutions for fractional differential equations with integral boundary and parameter.By applying a fixed point theorem of mixed monotone operator,we not only obtain a unique positive solution and construct two iterative sequences to approximate the solution,but also prove some useful properties of positive solution with respect to λ.At last,an example is given for illustrating our main results....

Adaptive Soft Sensing Model Based on OBE-PLS for System Identification

Time-varying and working-conditiontransition are the main problems in the industrial process.However,the staticsoft sensor model based on the fixed sample cannot track the currentobject,which leads to a poor prediction performance.In this paper,a dynamicsoft sensor modeling approach based on the optimal bounding ellipsoid (OBE)and the partial least squares (PLS) algorithm was proposed.Firstly,the PLSsoft sensor model based on offline data set is built.When a new query samplearrives,the statistics...
