Decision Tree Algorithm Examples in Data Mining
In the binary splitting method, the tuples are split and each split cost function is calculated. The lowest cost split is selected. The splitting method is binary which is formed as 2 branches. It is recursive in nature as the same method (calculating the cost) is used for splitting the other tuples of the dataset.
Laboratory Methods of Sample Preparation
Sample preparation method and Laboratory sampling procedures involve either: Coning and Quartering; or Riffling Method. Coning and Quartering for sample preparation techniques/method The method which is used for sampling large quantities of material say 20kg, consists of pouring or forming the material into a conical heap upon a solid surface (e.g. a steel plate) and relying on radial symmetry
