For example, a setting where the Naive Bayes classifier is often used is spam filtering. Here, the data is emails and the label is spam or not-spam. The Naive Bayes assumption implies that the words in an email are conditionally independent, given that you know that an email is spam or not. Clearly this is not true. Neither the words of spam or not-spam …
Classifier Predicates: A classifier (in ASL) is a sign that represents a general category of things, shapes, or sizes. A predicate is the part of a sentence that modifies (says something about or describes) the topic of the sentence or some other noun or noun phrase in the sentence. (Valli & Lucas, 2000)

Hydraulic Pumps. Pumps are mechanical devices that use prime mover energy to move fluids from one place to another. Positive displacement pumps apply pressure directly to the liquid using reciprocating or rotating components. The main types of positive displacement pumps are reciprocating pumps like piston pumps and diaphragm …
Here is its description: For each domain, we calculate the difference in performance of the two classifiers. We rank the absolute values of these differences and graft the signs in front of the ranks. We calculate the sum of positive and negative ranks, respectively (WS1 and WS2) TWilcox = min (WS1,WS2) Compare to critical value Vα.

This document discusses different types of classifiers used to separate particles by size: mechanical, hydraulic, hydrocyclone, and centrifugal air classifiers. It describes their basic working principles, which involve using settling velocity differences in water or air to separate coarse and fine particles.
This means that the hydrocyclone is also a classifier if the range of size of particles present in the feed stream is such that large will pass to the outer vortex and small will be entrained in the inner vortex (see Classifiers ). The mineral processing industry uses hydrocyclones in this way.
