The performance of credit scoring models is determined by the used features. The relevant features for credit scoring usually are determined unsystematic and dominate by arbitrary trial. This paper presents a comparative study of four feature selection methods, which use data mining approach in reducing the feature space. The final results show that among the four feature selection methods, the...

In this paper, the problem of stabilizing an open-loop unstable second-order system with time delay is considered. A constant feedback gain is utilized to stabilize the system. Using a modified version of Hermite-Biehler Theorem, which is applicable to quasi-polynomialsthe complete set of stabilizing constant feedback gains for open-loop unstable plants, is determined. The desired closed-loop p...

The effect of ordinary and restricted selection indices on body weight at different ages changes in birth weight of Iranian Moghani sheep was studied. Traits in the aggregate genotype were birth weight (BW), body weights at 3 (BW3) and 12 months of age (BW12). Two ordinary selection indices (I1 and I2) and two restricted selection indices (R1 and R2) were constructed. BW and BW3 were included i...

The body measurements of 433 young Dorper rams participating in the Free State and Northern Cape veld-ram projects were correlated with their production performance. These measurements included a selection index, body weight (kg), average daily gain (g/day) and scrotal circumference (cm). The performance of the animals in the two projects compared well, although the means in the Free State proj...

Developing effective selection programs for improving the performance of livestock requires taking the economical selection indices into account. The present study was performed for comparing four selection indices developed in Kermani sheep through simulated data. The relative importance of traits was determined based on the estimated economic values and consequently, the most beneficial trait...

Genetic improvement of exotic and indigenous pigs in tropical developing countries is desired. Implementations of traditional selection methods on tropical pig populations are limited by lack of data recording and analysis infrastructure. Genome-wide selection (GS) provides an approach for achieving faster genetic progress without developing a pedigree recording system. The implications of GS o...
