With referring to the teaching idea teaching methods and teaching modes of pre-employment training institution, taking the project cases as impelling force of teaching task, this paper comes up with “embedded teaching mode”. It is hoped to reform the course of theoretic teaching and practical teaching, construct the basic theoretic teaching system of information course, the project cases-based teaching...
This paper analyses the correlation of the data indicators of tourism economy resources firstly. Because there are higher nonlinear and larger volatility with the analysis and forecasting of tourism economy, this paper gives the analysis and forecasting model of tourism economy based on improved support vector regression (SVR) secondly. All kinds of kernel function are used in the numerical test based...
Least squares support vector machine (LS-SVM) has been widely used in engineering practice, using for reference algorithm of combinatorial optimization, this paper puts forward the combinatorial optimization least squares support vector machine algorithm (COLS-SVM). Based on algorithmic analysis of COLS-SVM, it can be used on individual credit evaluation and compared with Lagrange support vector machine...
LS-SVM(least squares support vector machine) has been widely used in engineering practice. However, the solving of LS-SVM still remains difficult under the condition of large sample. Based on algorithm of combinatorial optimization, this paper put forward the combinatorial optimization least squares support vector machine algorithm. On several different data aggregation of dimensions, the numerical...
The forecast of the mine Ground-water-level is an issue with many influencing factors, highly non-linear and temporal series. SVR (Support Vector Regression) is applied to forecast Coal Mine Ground-water-level in this paper. Appropriate kernel function and parameters are chosen based on the analysis to SVR regression algorithm. This paper proposes the Forecasting Model of Coal Mine Ground-water-level...
