A Data Forward Stepwise Fitting Algorithm Based on Orthogonal Function System

Data Reduction Algorithm Based on Planar Surface Fitting

Data reduction tools are developed and evaluated using a data analysis framework. Simple and intelligent thinning algorithms are applied to both synthetic and real data and the thinned datasets are ingested into an analysis system. A major problem of data reduction is that certain types of camera or scanner produce vast amounts of data, the processing of which presents serious problems. Rather ...

A hybrid customer prediction system based on multiple forward stepwise logistic regression mode

In today’s world, customer purchasing behavior prediction is one of the most important aspects of customer attraction. Good prediction can help to develop marketing strategies more accurately and to spend resources more effectively. When designing a customer prediction system (CPS) two issues are key, namely, feature selection and the prediction method to be used. Furthermore, it seems necessar...

An iterative orthogonal forward regression algorithm

A novel iterative learning algorithm is proposed to improve the classic orthogonal forward regression (OFR) algorithm in an attempt to produce an optimal solution under a purely OFR framework without using any other auxiliary algorithms. The new algorithm searches for the optimal solution on a global solution space while maintaining the advantage of simplicity and computational efficiency. Both...

An Elastic Net Orthogonal Forward Regression Algorithm

In this paper we propose an efficient two-level model identification method for a large class of linear-in-the-parameters models from the observational data. A new elastic net orthogonal forward regression (ENOFR) algorithm is employed at the lower level to carry out simultaneous model selection and elastic net parameter estimation. The two regularization parameters in the elastic net are optim...
