Beyond Additive Decompositions: Interpretability Through Separability
Researchers have introduced Tensor Separation Learning (TSL), a novel regression model designed to improve interpretability in machine learning. Unlike existing methods that rely on additive representations, TSL uses a sum of rank-1 products of univariate functions to avoid information loss from strong interactions. The model's separability ensures that visualizations are faithful to the fitted components, and it has demonstrated competitive performance against black-box models on regression benchmarks. AI
