spiral classifier java code

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

    java program to print a given matrix in spiral form

    Print the given matrix in spiral form in Java. Let’s look at the following example: Matrix M = 1 → 2 → 3. ↓ 4 → 5 6 ↑ ↓ 7 ← 8 ← 9. Spiral Order of this matrix M is 1 2 3 6 9 8 7 4 5 that is shown using arrows. In the above matrix number of rows are 3 so m=3, similarly n=3 as the number of columns is 3

    Mar 20, 2021 · A Polyspiral is a spiral made of multiple line segments, whereby each segment is larger (or smaller) than the previous one by a given amount. Each segment also changes direction at a given angle. Task. Animate a series of polyspirals, by drawing a complete spiral then incrementing the angle, and (after clearing the background) drawing the next, and so on
