Separators, Classifiers, and Screeners Information
Rake, spiral, and bowl classifiers use mechanical action to dewater, deslime or separate coarse bulk materials from finer materials or liquids. Drag classifiers consist of a chain-link conveyor or endless belt that is dragged through a solid-liquid mixture. Rake classifiers lift solid-liquid mixtures up onto a plate with a screen or rake.

Spiral Classifier for Mineral Processing
The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) inclined to the horizontal. The trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end. The spiral conveyor moves the solids which settle to the bottom upward toward ...

Scalable learning with polynomial kernel approximation
This is used to train linear classifiers that approximate the accuracy of kernelized ones. We use the Covtype dataset [2], trying to reproduce the experiments on the original paper of Tensor Sketch [1], i.e. the algorithm implemented by PolynomialCountSketch. First, we compute the accuracy of a linear classifier on the original features.

The Complete Guide to Classification in Python
This article serves as a reference for both simple and complex classification problems. By "simple", we designate a binary classification problem where a clear linear boundary exists between both classes. More complex classification problems may involve more than two classes, or the boundary is non-linear. For such problems, techniques …

Support Vector Machines explained with Python examples
SVMs share the characteristics of the margin classifiers that came before it. What is unique about them is how they can define both linear and non-linear decision boundaries. To support non-linear decision boundaries, SMVs use functions to transform the original feature space into a new space can represent those non-linear relationships.

How to classify data which is spiral in shape?
In the post we use tree, boosting and K nearest neighbor on spiral data. KNN is most intuitive one, it make the classification according to a given point's neighbors. So, spiral data would not "break the neighbor rule" For tree and boosting model, you can understand it as a "really complicated model that can achieve complied decisions".

With respect to the answer suggesting the usage of SVMs: Using SVMs is a sub-optimal solution to verifying linear separability for two reasons: SVMs are soft-margin classifiers. That means a linear kernel SVM might settle for a separating plane which is not separating perfectly even though it might be actually possible.
