A machine learning tournament was conducted to test twenty-one algorithms on a complex regression task involving a highly non-linear function defined by an image. The competition included standard algorithms like linear regression, k-NN, Random Forest, and gradient boosting methods (XGBoost, LightGBM, CatBoost), alongside neural networks. A novel deep architecture called the Polyharmonic Cascade, derived from random function theory, was introduced as an underdog contender. AI
