    General Spiral Equations: The central angle of a spiral (∆s) is a function of the average degree of curvature of the spiral. In other words, ∆s of a spiral is one half of the central angle (∆C) for a circular curve of the same length and degree of curvature. These measurements are dependent on the spiral length (LS) and central angle (∆S).

  • Spiral Classifier for Mineral Processing

    Mar 19, 2018· Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough which 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.

  • Building a 2 Layer Network to Classify a Spiral Dataset

    Sep 29, 2017· It is evident that no linear classifier will be able to do a good job classifying spiral data where the boundary between two classes is a curve. A simple two layer network with RELU activation on the hidden layer automatically learns the decision boundaries and achieves a 99% classification accuracy on such a data set.

    Generating Some DataTraining A Softmax Linear ClassifierTraining A Neural NetworkSummaryLets generate a classification dataset that is not easily linearly separable. Our favorite example is the spiral dataset, which can be generated as follows: Normally we would want to preprocess the dataset so that each feature has zero mean and unit standard deviation, but in this case the features are already in a nice range from -1 to 1, so we skip this step.
