An Efficient and Accurate Random Forest Node-Splitting Algorithm Based on Dynamic Bayesian Methods
Our deep-dive into this research reveals that BayesSplit introduces a novel node-splitting algorithm that extends MABSplit to improve the computational efficiency and predictive accuracy of Random Forests. BayesSplit treats the probability of impurity reduction as a Beta posterior distribution, iteratively refined based on batched observations. It uses posterior confidence intervals to adaptively select splits most likely to maximize impurity reduction. Key contributions include a Bayesian-based impurity estimation framework and two Bayesian optimization strategies: Dynamic Posterior Parameter Refinement and Posterior-Derived Confidence Bounding. The algorithm shows significant reductions in training time and improved generalization, particularly in resource-constrained environments.

BayesSplit: A Bayesian Node-Splitting Algorithm
The core of BayesSplit lies in its novel Bayesian-based impurity estimation framework, which treats impurity reduction as a Bernoulli event with Beta-conjugate priors. This approach allows for iterative refinement of beliefs about split effectiveness, naturally accommodating prior knowledge and new data for robust decision-making.
