Researchers have developed a new framework for interpretable machine learning by extending the Mixture of Experts (MoE) model. This novel approach allows for heterogeneous experts, incorporating decision trees, linear support vector machines, and quadratic discriminant analysis, alongside a probabilistic gating mechanism. The framework ensures coherent inference by calibrating non-probabilistic experts to produce class probabilities, enabling estimation within the Expectation-Maximization framework. Experiments show this method achieves competitive predictive performance while offering interpretable expert assignments and adaptive inductive bias selection. AI
