Beyond Accuracy and Complexity: The Effective Information Criterion for Structurally Stable Symbolic Regression
Zihan Yu, Guanren Wang, Jingtao Ding +2
Symbolic regression (SR) traditionally balances accuracy and complexity, implicitly assuming that simpler formulas are structurally more rational. We argue that this assumption is…

Linear Convergence in Hilbert's Projective Metric for Computing Augustin Information and a Rényi Information Measure
Chung-En Tsai, Guan-Ren Wang, Hao-Chung Cheng +1
Consider the problems of computing the Augustin information and a Rényi information measure of statistical independence, previously explored by Lapidoth and Pfister (IEEE Informati…

Computing Augustin Information via Hybrid Geodesically Convex Optimization
Guan-Ren Wang, Chung-En Tsai, Hao-Chung Cheng +1
We propose a Riemannian gradient descent with the Poincaré metric to compute the order- Augustin information, a widely used quantity for characterizing exponential error behavio…
