A Novel Data-Adaptive Regression Framework Based on Multivariate Adaptive Regression Splines for Electrocardiographic Imaging

Conclusion: MARS-based method successfully discovers the inverse mapping functions between the BSPs and EGMs yielding accurate reconstructions, and quantifies the contribution of each BSP lead. Significance: MARS-based method is adaptive, requires fewer parameter adjustments than NN-based methods, and is robust to errors. Thus, it can be a feasible data-driven approach for accurately solving inverse imaging problems.
