Spiral classification#

Classic two-dimensional nonlinear classification benchmark. Data points are sampled along two (or more) spiral functions and the neural network must learn to classify points by their spiral. Random effects are simulated by dividing the data into clusters and random varying the spiral radius in each cluster.

See synthetic_dataset/spiral_classification.ipynb for a comparison of conventional and mixed effects models. Spiral generation parameters can be varied to control the degree of random effects and, optionally, confounding effects.
