  • MEI Blog A brief history of classification in grinding

    Aug 09, 20140183;32;There was intermittent interest in hydro cyclones for wet circuits from 1891 but the Dorr rake classifier became available in 1902 and this unit and the Akins spiral classifier were used for wet classification from 1900 1950. By then the post war minerals boom had started and this required higher capacity processing units.

  • Assessing and Comparing Classifier Performance with ROC

    Threshold Selection. It is immediately apparent that a ROC curve can be used to select a threshold for a classifier which maximises the true positives, while minimising the false positives. However, different types of problems have different optimal classifier thresholds. For a cancer screening test, for example,

  • What are the disadvantages of using a naive bayes for

    Answer Wiki. The first disadvantage is that the Naive Bayes classifier makes a very strong assumption on the shape of your data distribution, i.e. any two features are independent given the output class. Due to this, the result can be (potentially) very bad hence, a naive classifier. This is not as terrible as people generally think,

    Spiral Classifier. In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow.
