Dynamic Integration of Data Mining Methods Using Selection
is necessary to evaluate and then select the most appropriate data-mining method or a group of methods Often the method selection is done statically without analyzing each new instance When the method selection is done dynamically taking into account the characteristics of each instance better results are achieved usually A general architecture of a knowledge discovery management system
The factors that influence the selection of mining ways
These factors among others are what will influence the selection of a mining method and the overall plan for developing the orebody Operating mines vary in size from small underground operations (some of these operations have only a few levels of production and may produce less than 100 tonnes of ore per day) to the large open pits (some of which move thousands of tonnes or ore and waste rock

Top 6 Regression Algorithms Used In Analytics Data
Top 6 Regression Algorithms Used In Data Mining And Their Applications In Industry Richa Bhatia 19/09/2017 Regression algorithms fall under the family of Supervised Machine Learning algorithms which is a subset of machine learning algorithms One of the main features of supervised learning algorithms is that they model dependencies and relationships between the target output and input
A Novel Trigger Model for Sales Prediction with Data
Examples are the Delphi method (Linstone Turof 1975) the brain storm method (Tremblay Grosskopf Yang 2010) the subjective probability method (Hogarth 1975) and so on These methods use the experience of experts or the integration of predicted results In contrast the objective prediction method uses raw data to build models based on mathematics and mathematical statistics methods
Selection and Strategy of Underground Mining Method
The mining technology of mine is not balanced the utilization of resources is low and the underground mining is easy to cause environmental problems In order to solve these problems in the mining of metal mines the underground continuous mining technology is used in the mining of metal mines In this paper on the basis of the selection of the mining method of metal mines and the

FEATURE SELECTION METHODS AND ALGORITHMS
Abstract— Feature selection is an important topic in data mining especially for high dimensional datasets Feature selection (also known as subset semmonly used in machine lection) is a process co learning wherein subsets of the features available from the data are selected for application of a learning algorithm The best subset contains the least number of dimensions that most contribute
Data Selection
Data selection is defined as the process of determining the appropriate data type and source as well as suitable instruments to collect data Data selection precedes the actual practice of data collection This definition distinguishes data selection from selective data reporting (selectively excluding data that is not supportive of a research hypothesis) and interactive/active data selection
UBC Mining Method Selection
The UBC selection method utilizes deposit depth primarily to climinate or restrict the use of open pit mining Open pit mining is such a versatile uiining method that itis vistually always the most applicable mining method when depth is not considered This modification reduces the applicability of open pit mining for deeper deposits 'The UBC mining method selection classifies rock mechanics
