WebJun 5, 2012 · Two-Nest-Spirals problem is a well-known classification benchmark problem. It contains two nested spirals, ‘o’ and ‘+’, as shown in figure. The task is to separate the two nested spirals. Suppose that we have 152 associations formed by assigning the 76 points … WebNeural Network for Solving the Two-Spiral Problem. This is a simple implementation of a 2-M-1 neural network trained using different optimization algorithms in order to solve the two-spiral problem. The two-spiral problem is a particularly difficult problem that requires separating two logistic spirals from one another [1] [2].
