Spiral Classifier for Mineral ProcessingMar 19, 2018 · Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semicylindrical trough (a trough which is semicircular in crosssection) inclined to the horizontal. The trough is provided with a slowrotating spiral conveyor and a liquid overflow at the lower end. Mining Spiral Classifier,New Ore

see full list on svds by this point, youve hopefully become convinced that plain classification accuracy is a poor metric for realworld domains. what should you use instead? many other evaluation metrics have been developed. it is important to remember that each is simply a different way of summarizing the confusion matrix. here are some metrics youll likely come across: 1. true positive rate= tp/(tp+fn) = 1 false negative rate 2. false positive rate= fp/(fp+tn) = 1 true negative rate 3. sensitivity= true positive rate 4. specificity= true negative rate 5. positive predictive value= tp/(tp+fp) 6. recall= tp / (tp+fn) = true positive rate 7. precision= tp / (tp+fp) 8. fscoreis the harmonic mean of precision and recall: 9. gscoreis the geometric mean of precision and recall: two other measures are worth mentioning, though their exact definitions are too elaborate to explain here. cohens kappa is a measure of agreement that takes into account how much agreement could be expected by chance. it does see full list on svds given all of these numbers, which is the right one to measure? well avoid the customary statistics answer (it depends), and answer: none of the above. the confusion matrix contains frequencies of the four different outcomes. the most precise way to solve the problem is to use these four numbers to calculate expected cost (or equivalently, expected benefit). you may recall that the standard form of an expected value is to take the probability of each situation and multiply it by its value. we convert the numbers in the matrix above, then we have to the costs and benefits for each of the four. the final calculation is the sum: expected cost = p(p)×cost(p) + p(n)×cost(n) here p(p) and p(n) are the probabilities of each class, also called the class priors. cost(p) is shorthand for the cost of dealing with a positive example. what is this? we have to break it apart into two cases: if we get it right (a true positive) and if we get it wrong (a false negative). cost(p) = p(true positive see full list on svds if youve read this far, you may be thinking: wait, what happens if i dont have error costs? what if they change? what if i want to see graphs of performance? isnt there anything i can get besides a simple point estimate? and if estimated cost is the simple answer to everything, why did scikitlearn implement dozens of different metrics? all good questions. the next blog post, part 2, will answer them. see full list on svds companyganzhou gelin mining machinery co., ltd.ganzhou gelin mining machinery co., ltd. is an over 30 s experience expert manufacturing mining machines in china, covering an area of over 30,000 square meters, having more than 25 sets of heavy processing equipments and with an annual output of more than 2000 sets of mining machinery. kogelbergbiospherereserveonestop service for mineral xin hai mining product. shandong xinhai mining technology ampequipment inc, is a stockhing high and new technology enterprise to provide turnkey solution for mineral processing plant including design and research, machine manufacturing, equipment procurement, management service, mine operation, mine materials procurement ampmanagement as well as industry resources integration. 3
