Common CT imaging signs of lung diseases (CISLs) are defined as the imaging signs that frequently appear in lung CT images from patients and play important roles in the diagnosis of lung diseases. This paper proposes a new feature selection method based on FIsher criterion and genetic optimization, called FIG for short, to tackle the CISL recognition problem. In our FIG feature selection method, the...
In view of the shortcomings of traditional multi-objective optimal methods, this paper introduces iSIGHT which is a kind of optimal design software. Based on optimal design framework Isight, the multi-objective optimal design method and step using the Neighborhood Cultivation Genetic Algorithm (NCGA) are investigated. Taking a multi-objective optimal design of spring as the example, the Pareto optimal...
An improved vehicle coordination strategy for vehicle routing problem (VRP) based on SWEEP was proposed in order to solving single-depot VRP with stochastic demands. In this strategy, the vehicle routing that customers were not served by basic vehicle (BV) is re-optimized using SWEEP rules, then these customers are severed by SWEEP vehicle (SV) in order that the total serve time will be less and the...
We consider the problem of modelling piecewise fractional autoregressive integrated moving-average (FARIMA) model signal. The number m of break points as well as their locations, the order (p, q) and the parameters of each regime are assumed to be unknown. To estimate the unknown parameters, we propose a criterion based on the minimum description length (MDL) principle of Rissanen. A genetic algorithm...
We consider the problem of estimating the structural breaks in a long memory FARIMA process. The number m of break points as well as their locations, the order (p, d, q) and the parameters of each regime are assumed to be unknown. To estimate the unknown parameters, we propose two criteria based on the minimum description length (MDL) principle of Rissanen, namely a direct extension of MDL and an...
